Key takeaways
- Darwin Airline was a historic Swiss regional airline from Lugano: founded in 2003, scheduled service from July 2004, bankruptcy in December 2017.
- Codes: IATA F7 (taken over from Baboo in 2011), ICAO DWT, callsign “DARWIN”.
- The Saab 2000 as the backbone: the fast 50-seater defined the airline from start to finish, supplemented from 2014 by four ATR 72-500s.
- Etihad Regional: after Etihad Airways came in, Darwin flew under the Gulf airline’s brand from January 2014 – with a large network that shrank again as early as 2015.
- Three names, one airline: Darwin, Etihad Regional and Adria Airways Switzerland – for spotters the registration counts, not the titles.

How to recognize the airline
Is that really Darwin Airline?
- Swiss registration with HB- – at Darwin almost always on a turboprop
- Type mix of the Saab 2000 (slim fuselage, engines with six-blade propellers set far forward on the wing) and the ATR 72-500 (high-wing)
- From January 2014 “Etihad Regional” titles in the style of the Etihad family, with the addition “operated by Darwin Airline”
- From late summer 2017 the Adria Airways Switzerland brand look – in the last months mainly on the Saab 2000s
- Flight number with F7, DWT and “DARWIN” on the tracker and on the radio
- Home in Ticino: photos from Lugano-Agno with a mountain backdrop are the typical Darwin shots
Darwin Airline is one of those airlines that many spotters have photographed without realizing it. Sometimes “Darwin” was on the fuselage, sometimes “Etihad Regional”, at the very end “Adria Airways Switzerland” – behind it was always the same small company from Ticino. This page sorts out the history of the Lugano airline, explains its fleet of Saab 2000s and ATR 72-500s and shows you how to attribute old photos cleanly.

Darwin Airline at a glance
Darwin Airline was a Swiss regional airline based near Lugano. It was founded on August 12, 2003 – at a time when Ticino was at risk of losing its air links: Swiss had dropped Lugano from its own network. Darwin stepped into the gap. The airline started its first scheduled flight on July 28, 2004 from Lugano to Geneva, shortly after the Federal Office of Civil Aviation (BAZL) had granted the operating license.
Several founders stood behind the airline, including pilots, and in the cockpit as well as the cabin there were initially many people from the former Crossair. That fits: the Basel regional airline had shaped Lugano for many years and was launch customer for exactly the aircraft type with which Darwin began operations – the Saab 2000.
Darwin always remained a small airline. Around 300 employees and a fleet in the low double digits were the maximum. What makes the story exciting is the many changes: takeover of Baboo, Etihad coming in, a restart as Adria Airways Switzerland – and in the end bankruptcy in December 2017.
Codes and callsigns
- IATA code F7: appeared in the flight number. What distinguishes the two code systems is explained in the article on IATA and ICAO codes. Darwin took it over in March 2011 along with the business of the Geneva regional airline Baboo. Before that, Darwin flew with a different IATA code of its own.
- ICAO code DWT: appeared in the air traffic control flight plan and therefore on the flight trackers.
- Callsign DARWIN: this is how the crews called in on the radio – also in the time as Etihad Regional.
Important for your archive: the brand changed, the codes did not. An Etihad Regional flight was still “DARWIN” on the radio and DWT in the flight plan. If you evaluate old tracker data or radio recordings, you therefore find the airline under the same code across all brand phases. How to research an aircraft’s past flights is shown in the guide on an aircraft’s flight history.
F7 is not always F7
Before 2011 the IATA code F7 belonged to the Geneva-based Baboo. Photos or timetables with F7 from the years up to 2010 therefore concern Baboo, not Darwin. Pay attention to the date when sorting.
History: from Lugano to bankruptcy
2003 to 2010: Ticino restart with the Saab 2000
Darwin began with a clear task: to connect Lugano with the big Swiss airports and abroad again. The first route was Lugano–Geneva, and further destinations were added step by step. The home base was on the grounds of Lugano Airport in Agno; in 2009 Darwin also took over the maintenance department at the airport.
The aircraft flown was the Saab 2000. The 50-seat turboprop was well suited to the short runway and the demanding approach in the Ticino valley and fast enough to also fly longer routes in Europe economically. Only 63 examples were built by manufacturer Saab, a large share of them going to Crossair.
2011: Baboo, a new code and the Dash 8 Q400
At the end of 2010 the Geneva regional airline Baboo was in trouble. In November 2010 Darwin announced that it would take over routes and parts of the business; the takeover was completed in March 2011. That made Geneva the second base, and Darwin flew from then on under the IATA code F7.
With Baboo, two Dash 8 Q400s with 74 seats each also joined the fleet. They remained a short chapter: for Darwin’s network the larger turboprops had too much capacity and were sold again.
2013 to 2017: Etihad Regional
The big upheaval came at the end of 2013. In November Etihad Airways announced that it would take around one third of the shares (33.3 percent); the BAZL, however, did not approve the stake until April 2015. The Gulf airline was then taking stakes in several European airlines – including Air Berlin, Alitalia and Air Serbia, and outside Europe for example Air Seychelles. Darwin was to serve as a feeder for Etihad flights from Europe. You can read more about the Gulf carriers’ model in the article on Emirates, Qatar Airways and Etihad.
From January 2014 Darwin appeared as Etihad Regional. The first aircraft in the new design flew on January 17, 2014. In addition came four ATR 72-500s, which Darwin leased from Nordic Aviation Capital. Through codeshares, Etihad Regional was supposed to feed its partner’s long-haul routes to Abu Dhabi – but the necessary approvals took a long time to arrive.
The network grew fast – and shrank just as fast. At times the airline served routes from Leipzig/Halle and Dresden, plus connections to France, Austria and Italy. In Italy Darwin lost several domestic routes to Rome in 2014, for example from Ancona and Trapani, because an exemption from the cabotage rules for Swiss airlines was not extended; Aosta–Rome never even got started. The Lugano–Zurich route, which Darwin flew for Swiss, ended in October 2014. On February 18, 2015, Darwin then discontinued around two thirds of its routes without prior notice; by March 2015 all connections in Germany and the Leipzig/Halle base were gone as well.

Flying for others: wet lease as a second pillar
After withdrawing from the large network, Darwin focused more on operating flights on behalf of other airlines – classic wet lease. From 2015 the four ATR 72-500s flew domestic routes for Alitalia, and some Saab 2000s were flying for Air Berlin from April 2015 – that contract ended in spring 2016. Darwin also flew for Bern-based SkyWork Airlines at times; SkyWork ended the cooperation at the end of 2015.
For spotters, precisely this phase makes attribution tricky: an aircraft in Etihad Regional livery could fly under an Alitalia or Air Berlin flight number. The registration is what matters then, not the flight number.
2017: Adria Airways Switzerland and the end
In July 2017 Etihad and the other shareholders sold their shares to the Luxembourg holding company 4K Invest, which also owned the Slovenian Adria Airways. Darwin remained a company of its own, but from late summer 2017 appeared as Adria Airways Switzerland. The Etihad brand disappeared.
It did not last long. The Air Berlin contract had already expired in 2016, and in 2017 Alitalia, the most important remaining wet-lease partner, also went insolvent. At the end of November 2017 Darwin announced that it would close the Lugano base and applied for creditor protection. On November 28, 2017, the BAZL revoked the operating license for scheduled flights, and on December 12, 2017 the company was declared insolvent and dissolved. The leased ATR 72-500s were due to leave the fleet in early 2018 anyway. You can find more on such collapses in the overview of major airline failures in Europe.
| Year | Event | Spotter relevance |
|---|---|---|
| 2003 | Founded in Lugano | – |
| 2004 | First scheduled flight Lugano–Geneva | Saab 2000 in the Darwin design |
| 2011 | Takeover of Baboo, code F7 | Geneva as second base, briefly Dash 8 Q400 |
| 2014 | Etihad Regional brand | New design, ATR 72-500s join |
| 2015 | Sharp network cuts, wet lease for Alitalia and Air Berlin | Foreign flight numbers on Darwin aircraft |
| 2017 | Adria Airways Switzerland, license revoked, bankruptcy | Last design, end of flight operations |
The fleet
For long stretches Darwin was a pure Saab 2000 airline. Only with Etihad did a second type join permanently.
| Type | Period | Seats | Role | Spotter tip |
|---|---|---|---|---|
| Saab 2000 | 2004–2017, finally 6 | 50 | Backbone of the fleet | Long, slim fuselage, low wing, six-blade propellers |
| ATR 72-500 | from 2014, 4 leased | 68 | Expansion from Geneva, later flights for Alitalia | High wing, leased from Nordic Aviation Capital |
| Dash 8 Q400 | from 2011, 2 | 74 | Legacy of Baboo | In service only briefly, sold again |
The Saab 2000 is the type that defines Darwin. With its engines set far forward on the wing and its long fuselage, it looks larger and more stretched than the smaller Saab 340. It was one of the fastest turboprops of its time – which is why Crossair called it the “Concordino”. Because only a few examples were built, every sighting today is something special.
The ATR 72-500 from the manufacturer ATR, by contrast, is a mass-market type: high-wing, landing gear in fairings on the fuselage, easily recognized by the high wing above the cabin. For Darwin it was the step toward more capacity on the new Etihad Regional routes.
How to recognize the Saab 2000
- Low wing – the wing sits under the fuselage
- Six-blade propellers, engines far ahead of the wing leading edge
- Long, slim fuselage with many windows
- Horizontal stabilizer low at the fuselage end, not on top of the vertical stabilizer
How to recognize the ATR 72-500
- High wing – the wing sits on top of the fuselage
- Main landing gear in fairings on the side of the fuselage
- Horizontal stabilizer high on the vertical stabilizer (T-tail)
- Six-blade propellers, engines under the wing
If you are generally unsure about turboprops, the comparison in Telling the ATR 42/72 and Dash 8 apart helps.
How to recognize Darwin aircraft
At Darwin the date of the photo decides which design you are looking for. Three phases can be distinguished:
2004 to 2013: Darwin Airline
Saab 2000 in the Darwin look of its own, home Lugano and from 2011 also Geneva. From 2011 briefly also Dash 8 Q400s from the Baboo legacy.
2014 to mid-2017: Etihad Regional
“Etihad Regional” titles in the style of the Etihad family, with the addition “operated by Darwin Airline”. Saab 2000 and ATR 72-500.
From late summer 2017: Adria Airways Switzerland
Last brand look, in service for only a few months – mainly on the Saab 2000s.
Always the same: registration and code
Swiss HB registrations, ICAO code DWT. That lets you assign every phase to the same airline.
The registrations begin, as on all Swiss aircraft, with HB-. How the Swiss registration is structured and which blocks exist is explained in the article on Swiss HB registrations. Because Darwin aircraft changed their brand several times, it is also worth looking at hybrid and mixed liveries and at the topic of livery changes and rebranding: especially in transition periods, aircraft flew with a half-new, half-old look.
Watch out for mix-ups
An aircraft with “Etihad” titles at a Swiss regional airport is not an offshoot of the Gulf airline with a license of its own. Etihad Regional was a brand; Darwin Airline did the flying. So record DWT as the operator, not ETD.
Where you saw Darwin – and where today
The classic Darwin places were Lugano and Geneva. Lugano, with its short airfield between the mountains, was home, and Geneva from 2011 the second base and in the Etihad era the center of the network. If you photographed in Geneva, you will often find the Saab 2000 and ATR in old pictures from the observation deck at Geneva Airport; tips for the place today are in the Geneva plane spotting guide. For Leipzig/Halle, where Darwin had a base from 2013 to 2015, the Leipzig/Halle spotting guide helps.
Zurich was added – for example on the route to Lugano, which Darwin flew for Swiss until October 2014 – and in the Etihad phase airports in Germany, Austria, France and Italy. In Zurich, the Butzenbüel was already a good choice for turboprops back then; more in the Zurich plane spotting guide.
Today you no longer see Darwin in scheduled service. For your logbook the airline is an archive topic. The chance lies in old photos: if you were out in Lugano, Geneva or Zurich between 2004 and 2017, you may well have several Darwin phases in the can.
Probably Darwin if …
- a Saab 2000 with an HB registration can be seen in Lugano or Geneva between 2004 and 2017
- “Etihad Regional” is on a turboprop
- the tracker or radio shows DWT or “DARWIN”
Look more closely if …
- a Saab 2000 dates from before 2004 – then it was more likely Crossair or Swiss
- the flight number belongs to Alitalia, Air Berlin or SkyWork
Definitely not Darwin if …
- F7 appears on a flight before 2011 – that was Baboo
- the photo was taken in scheduled service after December 2017
Darwin in the context of Swiss regional aviation
Darwin belongs to a line of Swiss regional airlines that came and went. Model and predecessor in Ticino was Crossair, which was absorbed into Swiss in 2002. In parallel to Darwin, SkyWork Airlines flew in Bern and also gave up in 2018. From this generation it is mainly Helvetic Airways that has survived, today flying heavily for Swiss. If you want to understand the big airlines, it is best to also read the page on Swissair and the overview of regional airlines in Europe.
The Etihad episode also shows how closely small airlines can be tied to large investors: when Etihad wound down its European equity network and partners such as Air Berlin and Alitalia failed, Darwin lost its foundation.
Common mix-ups
- Taking Etihad Regional for an Etihad subsidiary with its own license – the operator was always Darwin Airline SA with the ICAO code DWT.
- Assigning F7 before 2011 to Darwin – the code belonged to Baboo until then.
- Attributing every Saab 2000 in Lugano to Darwin – before 2004 Crossair flew there, and afterward Swiss, with the same type.
- Confusing the Saab 2000 and ATR 72 – low wing versus high wing, the wing feature is unambiguous.
- Equating the flight number with the operator – in the wet-lease phase, Darwin aircraft flew under Alitalia or Air Berlin numbers.
- Taking Adria Airways Switzerland for Adria Airways – the Swiss company remained legally Darwin.

Conclusion
Darwin Airline was small but eventful: founded to connect Ticino, grown through Baboo, inflated as Etihad Regional and in the end a victim of its partners’ crises. For spotters it remains remembered above all as a Saab 2000 airline – and as a lesson that titles change, but registrations and the ICAO code stay.
In short
Darwin Airline (IATA F7, ICAO DWT) was a historic regional airline from Lugano (2003–2017) with the Saab 2000 and ATR 72-500. Whether Darwin, Etihad Regional or Adria Airways Switzerland – it was always the same company.
Summary
- Darwin came into being in 2003 in Ticino after Swiss dropped Lugano from its network, and from 2004 flew the Saab 2000 between Lugano and Geneva.
- With the takeover of the Geneva-based Baboo, new routes, the IATA code F7 and, briefly, two Dash 8 Q400s were added in 2011.
- Etihad Airways came in at the end of 2013; as Etihad Regional, Darwin expanded the network sharply, but had to scale it back step by step from 2014.
- After the sale to the owners of Adria Airways, the airline flew briefly as Adria Airways Switzerland, lost its license in November 2017 and went bankrupt in December 2017.
Frequently asked questions
What IATA and ICAO code did Darwin Airline have?
Darwin Airline most recently flew with the IATA code F7 and the ICAO code DWT, and the radio callsign was “DARWIN”. Darwin took over the IATA code F7 in March 2011 along with the business of the Geneva regional airline Baboo; before that the airline used a different code.
What is the difference between Darwin Airline and Etihad Regional?
It was the same company. From January 2014, Etihad Regional was the brand name under which Darwin Airline SA sold its flights and painted its aircraft. In the legal sense the airline remained Darwin – which is why “operated by Darwin Airline” also appeared in the branding, and the codes F7 and DWT stayed the same.
What aircraft did Darwin Airline fly?
The backbone was the Saab 2000, a fast 50-seat turboprop. From 2014 four leased ATR 72-500s with 68 seats were added. With the takeover of Baboo, two Dash 8 Q400s also briefly flew at Darwin and were given back because their capacity was too large. At the end the fleet consisted of six Saab 2000s and four ATR 72-500s.
How large was Etihad’s stake in Darwin?
Etihad Airways announced in November 2013 that it would take around one third of the shares (33.3 percent); BAZL approval did not follow until April 2015. Darwin thus became part of the Gulf airline’s equity strategy, which also included Alitalia, Air Berlin, Air Serbia and Air Seychelles. In July 2017 Etihad sold the shares to the holding company that also owned Adria Airways.
Why did Darwin Airline go bankrupt?
The large Etihad Regional network performed poorly and was cut back several times from 2014. The wet-lease contract for Air Berlin ended as early as spring 2016, and in 2017 Alitalia, the most important remaining customer, itself went insolvent. At the end of November 2017 Darwin applied for creditor protection, the BAZL revoked the operating license on November 28, 2017, and bankruptcy followed on December 12, 2017.
What was Adria Airways Switzerland?
That is what Darwin Airline was called in its last months. In July 2017 the Luxembourg holding company 4K Invest, owner of the Slovenian Adria Airways, bought the shares. Darwin remained a company of its own, but from late summer 2017 appeared as Adria Airways Switzerland. Adria Airways itself went bankrupt in 2019.
Can I still see Darwin Airline aircraft today?
Not in scheduled service – the airline has not existed since the end of 2017. Individual former Darwin aircraft may have turned up later with other operators. If you want to trace a registration from your archive, the aircraft’s flight history will help you.

Aircraft types in the fleet
Saab 2000
Low-set wings, six-blade propellers and a fuselage that looks unusually long for a turboprop: the Saab 2000 was Sweden’s fast regional airliner. Here is how to recognize it and find the last survivors.
Aircraft typeATR 72-500
Six propeller blades, high wing, T-tail – and almost impossible to tell from the -600 on the outside: the ATR 72-500 is the most-built ATR 72 before the current generation. Here is how to tell it apart cleanly.
Aircraft typeDe Havilland Canada Dash 8-400 (Q400)
High wing, T-tail, six-blade propellers and landing gear that folds rearward into the engine nacelles: the Dash 8-400 is the fastest and largest regional turboprop in scheduled service. Here is how to identify it with confidence.
Aircraft typeSaab 340
Low wing, two four-blade propellers, an ordinary tail and a short, rounded fuselage: the Saab 340 is the Swedish classic among regional turboprops. Here is how to recognize it and where it still flies today.

Spotting locations where this airline can be seen regularly – with vantage points, light times and coordinates.
Observation terrace at Geneva Airport
On the fourth floor of Terminal 1 you look over the apron onto Switzerland’s longest runway and the Jura range behind it. The Terrasse Panorama costs nothing, you get in without security screening – and thanks to business aviation, an easyJet base and long-haul guests it is rarely boring. The only catch: it is open only from mid-March to the end of October.
Spotting hillButzenbüel and the spotter hill at Zurich Airport
The classic spotter hill at the Heligrill on the west side of Zurich Airport has been gone since September 2023, and the Butzenbüel is a park hill behind The Circle – not a spotter point. Here you learn what is going on with both places and where you can legally spot today in the west and around the fence.
