How to recognize the airline
Is that really Air One?
- Classic look similar to the old Lufthansa: white fuselage, gray underside, blue tail
- Stylized heron on the tail – “airone” is Italian for heron
- “Air One” titles on the fuselage, on the low-cost brand from 2010 with the addition “Smart Carrier”
- Until around 2008 almost always a Boeing 737, afterward mostly an Airbus A320
- Mostly Italian registrations with I-, a few leased aircraft with a foreign prefix
- Flight number with AP, in the air traffic control flight plan ADH or “HERON”
If you stood at the fence in Rome or Milan in the 1990s and 2000s, you knew the sight: a Boeing 737 with a blue tail that at first glance looked like Lufthansa – and then had “Air One” on the fuselage after all. Air One was the private challenger to Alitalia, founded by a construction entrepreneur from Abruzzo, closely entangled with Lufthansa and, in the end, of all things part of the airline it had flown against for years. This page shows you how Air One came about, which aircraft it flew, how to recognize it in old photos and how the story ended in 2014.

Air One at a glance
Air One was an Italian airline that existed from 1983 to 2014 – first under the name Aliadriatica, from 1995 as Air One. Its rise is closely tied to one name: Carlo Toto, an entrepreneur from Abruzzo, took over the small company in 1988 and within a good ten years turned it into Italy’s second-largest airline. In 2007 Air One carried, depending on the source and the way of counting, between a good five and about seven million passengers.
The focus was on domestic traffic, above all on the trunk route between Rome Fiumicino and Milan Linate. There Air One went head to head with the then state airline Alitalia. It found a partner in the north: from 2000 Air One worked closely with Lufthansa, and the look of the fleet was no accident reminiscent of the crane airline.
The end came in two steps. In 2009 Air One was absorbed into the newly restarted Alitalia. From 2010 the name lived on as the low-cost brand “Smart Carrier,” until Alitalia, in the course of its partnership with Etihad, dissolved this offshoot as well. The last flight operations ended on October 30, 2014.
The history in stages
The beginnings were modest. In 1983 seven shareholders founded Aliadriatica in Pescara. In its first years it flew no scheduled service but aerial work and air taxi missions. In 1988 Carlo Toto took over, whose family had grown big in construction with Toto Costruzioni Generali.
1983
Aliadriatica is founded in Pescara, initially with aerial work and air taxi.
1988–1991
Carlo Toto takes over the company. Besides business aircraft, two Jetstream 31 turboprops join the fleet.
1994/1995
Jet operations begin with the first Boeing 737-200. From April 27, 1995, Aliadriatica flies daily from Milan Linate to Brindisi, Reggio Calabria and Lamezia Terme.
November 1995
Renamed Air One and launch of the Rome–Milan route in direct competition with Alitalia.
2000
Partnership with Lufthansa, almost all flights run as codeshares.
2006–2008
Large Airbus order, launch of the regional subsidiary Air One CityLiner with CRJ900s, long-haul to the USA with A330-200s.
2009
On January 13, Air One becomes part of the newly restarted Alitalia.
2010–2014
Air One flies as the low-cost brand “Smart Carrier” until operations end on October 30, 2014.
It is remarkable how cautiously the entry into scheduled service went. The first routes from Linate complemented the Alitalia network rather than attacking it. Only with the new name in November 1995 did Air One go onto the route where the most money was made in Italy: Rome–Milan. At the end of 1999 the airline flew about 350 times a week to seven domestic destinations, with eleven Boeing 737s and about 700 employees.
Codes and callsign
- IATA code AP: appeared in the flight number, on tickets and departure boards.
- ICAO code ADH: used by air traffic control in the flight plan – a leftover from the Aliadriatica era.
- Callsign HERON: this is how the crews identified themselves on the radio.
The callsign is a small play on words. The name is pronounced “Air One” in English, but written as one word it gives “Airone” – the Italian word for heron. And the heron is called “heron” in English. The bird therefore also adorned the tail.
Codeshare in your logbook
From 2000 many Air One flights also carried a Lufthansa flight number. What matters for your logbook is the operating airline – that is, Air One with ADH. How such flight numbers come about is explained in the article Codeshare flights explained.
The fleet: from the Jetstream to the A330
Air One was for long stretches a Boeing 737 airline. The backbone was the 737-300 and 737-400, mostly leased. In early 2006 there were about 30 Boeing 737s in the fleet. Then came the switch to Airbus: in January 2006 Air One ordered 30 A320s with options on 60 more aircraft, and in May 2007 the order was increased to a total of 90 A320s.
| Type | Period at Air One | Spotter note |
|---|---|---|
| BAe Jetstream 31 | 1991–1993 | Two turboprops from the Aliadriatica era |
| Boeing 737-200 | from 1994, until 2008 | First jet, slim first-generation engines |
| Boeing 737-300 | 1995–2010 | Classic generation, in scheduled service from 1995 |
| Boeing 737-400 | 1997–2010 | Largest group in the fleet, 27 examples in total |
| Boeing 737-800 | 2002–2004 | Only a short episode with six aircraft |
| McDonnell Douglas MD-83 | 2006–2008 | One of a kind, leased from Spanair |
| Avro RJ70 | 2006–2009 | Two leased four-engine jets from Sweden |
| Airbus A320 | from 2006 | Replaced the 737, later the only type of the Smart Carrier |
| Airbus A330-200 | 2008–2009 | Two aircraft for the USA flights |
The information follows the fleet history in common reference works; individual numbers and exact years can differ slightly depending on the source. There were also other types leased briefly, such as a DC-9, a Fokker 50, a Saab 2000 and an ATR 42-300. The manufacturer of the most important types was Boeing.
If you are sorting old 737 photos of Air One, the guide Telling the Boeing 737 Original, Classic, NG and MAX apart helps. Between the 737-300 and 737-400, the fuselage length decides above all: the -400 is visibly stretched and has two overwing exits instead of one.
Air One CityLiner and the regional jets
In June 2006 Air One spun off its regional routes into a subsidiary of its own: Air One CityLiner. It flew new Bombardier CRJ900s. The subsidiary existed until 2009 and was then also absorbed into the Alitalia group. For your logbook the same applies as with many regional subsidiaries: visually it was Air One, but CityLiner operated the flights.
A short excursion into long-haul
In 2008 Air One ventured across the Atlantic. From June 14, 2008, Air One flew an Airbus A330-200 from Milan Malpensa to Boston, and from June 21 also to Chicago O’Hare. The two aircraft had 239 seats, 38 of them in business class. Partners on the US side were US Airways for Boston and United Airlines for Chicago.
In June 2008 Air One also ordered twelve A330s and twelve Airbus A350-900s. This order passed to Alitalia after the merger – Air One itself never operated an A350.

Lufthansa ties and Star Alliance
From 2000 Air One was firmly bound to Lufthansa. Almost all flights ran as codeshares, and Air One was also a partner in the Miles & More frequent flyer program. Lufthansa thus gained feeders in the Italian domestic network, and Air One gained access to a large European network – a constellation that fit well with the competition at the time between Lufthansa and the SkyTeam member Alitalia.
By mid-2006 Air One had codeshares with several members of Star Alliance, including Lufthansa, SAS, US Airways, TAP Air Portugal and Air Canada. In June 2006 management announced it was preparing to join the alliance – with Lufthansa’s support, at first possibly as a regional member.
Joining never happened. With its absorption into Alitalia, Air One practically switched to the SkyTeam camp. The partnerships dissolved in 2009: cooperation with Miles & More ended on March 28, 2009, and with the programs of United and Air Canada at the end of June 2009. How the three big alliances are built is explained in the article Star Alliance, oneworld and SkyTeam.
Irony of history
With ITA Airways, Alitalia’s successor now belongs to Star Alliance, and the Lufthansa Group holds a stake in it. What Air One was aiming for in the mid-2000s, Italian aviation has thus achieved after all, by a detour.
How to recognize Air One
The basic look was plain and striking at the same time: white fuselage, gray underside and a blue tail. Even in the Aliadriatica era the scheme recalled the classic Lufthansa livery, although Lufthansa held no stake in the airline then. From a distance Air One aircraft were therefore often mistaken for Lufthansa.
The detail made the difference: instead of the crane, Air One carried a stylized heron on the tail, plus the “Air One” titles on the fuselage. On the low-cost brand from 2010, the A320s kept flying in the Air One look, supplemented by the addition “Smart Carrier.”
Does your old photo really show Air One?
- Blue tail with a heron instead of a crane
- “Air One” titles on the fuselage
- Boeing 737 (until about 2010) or Airbus A320
- Italian registration with I- or a recognizably leased aircraft
- Shot from the time before November 2014
- Location such as Rome Fiumicino, Milan Linate, Malpensa, Pisa, Venice or Catania
After 2009 there were transition phases: former Air One aircraft flew for Alitalia, in part still with remnants of the old livery. The article on hybrid and mixed liveries helps place such mixed forms.
Alitalia’s competitor
Air One grew mainly at the expense of the state airline. In 2006 it put its share of the Italian domestic market, depending on the source, at about a quarter to just under a third, and Carlo Toto liked to stress that his airline had never received state money – unlike the partly state-owned Alitalia.
In 2007 Toto went a step further. When the Italian state wanted to sell Alitalia, Air One submitted an offer through the holding company AP Holding, backed by a banking group around Intesa Sanpaolo. In competition was Air France-KLM, which the government preferred. In early 2008 Air One even fought the exclusive negotiations with the French in court. The talks with Air France-KLM failed, however, in spring 2008.
What made Air One strong
- Lean, private structure without state legacy burdens
- Strong position on Rome–Milan
- Lufthansa as a partner with a large network
- Modern fleet after the Airbus order
What was missing in the end
- Capital for growth and long-haul
- A strong network beyond Italy
- Protection from low-cost airlines and high-speed trains
- Financial reserves to hold out alone against a newly reconstituted Alitalia
Merger with Alitalia and Smart Carrier
In August 2008 the solution that Italy ultimately chose became known: an investor consortium, Compagnia Aerea Italiana (CAI), took over the viable parts of Alitalia and merged them with Air One. Air One contributed almost its entire fleet. On January 13, 2009, the new Alitalia started, and Air One was officially part of it. Over the course of the year booking systems and processes were harmonized – the two airlines practically became one.
The name did not disappear anyway. On March 28, 2010, Alitalia launched Air One “Smart Carrier,” a low-cost brand with five A320s of 180 seats each from Milan Malpensa. At launch it served nine domestic and five international destinations. After that the network grew through new bases:
March 2010
Launch in Milan Malpensa with five A320s.
July 2011
New base in Pisa.
2013/2014
Malpensa closes in October 2013, in March 2014 Palermo is added.
In February 2013 the fleet consisted of nine A320s. On August 26, 2014, Alitalia announced the end – the restructuring with Etihad as majority shareholder no longer provided for a low-cost brand of its own. Catania, Palermo and Venice closed on September 30, 2014, and the remaining routes ended on October 30, 2014. Some of the connections and the aircraft went to Alitalia. In December 2014 the air operator certificate was revoked. The article Big airline collapses in Europe places this in the series of Italian airline failures and mergers.
Spotting today: only with backstory
You no longer see an aircraft in Air One scheduled service. What remains are archive photos and former Air One aircraft at other operators. Photograph them like any other aircraft only from publicly accessible areas.
Air One in everyday spotting today
For your logbook, Air One is a classic archive topic. If you photographed at Italian airports between 1995 and 2014, you have a good chance of an Air One 737 or an A320 on your memory card. With type, registration, place and date, these become clean entries.
The detective work is exciting. Many A320s from the Air One order kept flying with Alitalia after 2014, some later with ITA Airways. According to a report from early 2023, the last still recognizable ex-Air One example got the blue ITA colors at that time. How to trace an aircraft’s history through registration and serial number is explained in the guide How old is this aircraft?. And if you are in Rome today, you will find good vantage points in the guide Plane spotting in Rome Fiumicino.
Good chances of Air One traces if …
- you are going through your photo archive from before November 2014
- you are specifically looking for registrations of former Air One A320s
Check carefully if …
- a photo dates from 2009 to 2010 – the aircraft may already have flown for Alitalia then
- you only see a blue tail – that can also be Lufthansa
No chance of Air One if …
- you search the tracker today for ADH or “HERON” – the airline has not flown since October 2014
Italy’s private airlines compared
Air One was not the only private airline that shaped Italy at that time. Meridiana from Sardinia, Volare Airlines and Wind Jet from Sicily also tried their luck alongside Alitalia – none of them flies today. Meridiana became Air Italy in 2018, which gave up in 2020. Leisure airlines like Blue Panorama, by contrast, relied mainly on charter and vacation traffic. Air One differed from the others above all in its size and the Lufthansa partnership.
Common mix-ups
- Mistaking Air One for Lufthansa – white fuselage and blue tail looked similar, but Air One carried the heron instead of the crane.
- Logging Air One as a Star Alliance member – joining was announced but never completed.
- Equating Air One with Alitalia – until 2008 Air One was independent, only from 2009 part of Alitalia.
- Logging CityLiner CRJs as Air One – the regional jets were flown by the subsidiary Air One CityLiner.
- Taking the Smart Carrier A320s for an independent airline – from 2010 Air One was an Alitalia subsidiary.
- Assuming long-haul from Rome – the USA flights with the A330 started in 2008 from Milan Malpensa.

Conclusion
Air One was the most successful private challenger Alitalia ever had: from an air taxi operation in Pescara to the number two in the country, with Boeing 737s, later A320s and even a brief detour to the USA. Its closeness to Lufthansa and the planned Star Alliance membership made it the counterpart of the SkyTeam airline Alitalia – until the merger in 2009 brought the two together. For spotters, what remains is an airline that is easily mistaken for Lufthansa and therefore needs a close look.
In brief
Air One (IATA AP, ICAO ADH, callsign “HERON”) flew from 1995 until October 30, 2014 and was Italy’s largest private airline. The heron on the blue tail separates it from Lufthansa, the date from its later role as an Alitalia subsidiary.
Summary
- Air One grew out of Aliadriatica, a small aerial work and air taxi operation from Pescara that the construction entrepreneur Carlo Toto took over in 1988.
- With a fleet of Boeing 737s, Air One became Alitalia’s most important private competitor on domestic routes and worked closely with Lufthansa.
- From 2006 to 2008 came Airbus A320s, Bombardier CRJ900s of the subsidiary Air One CityLiner and two A330-200s for flights from Milan Malpensa to the USA.
- After Alitalia’s restart in 2009, Air One was absorbed into it; as “Smart Carrier” the brand flew A320s until October 2014 from bases like Pisa, Venice and Catania.
Frequently asked questions
What were Air One’s IATA and ICAO codes?
Air One flew with the IATA code AP in the flight number and the ICAO code ADH. On the radio the crews used the callsign “HERON” – a nod to the name, because “airone” means heron in Italian.
Who was behind Air One?
From 1988 the airline belonged to the entrepreneur Carlo Toto, whose family is mainly active in construction. The predecessor Aliadriatica had been founded in 1983 by seven shareholders in Pescara. Toto expanded it into a scheduled airline and led it as president.
Was Air One a member of Star Alliance?
No. From 2000 Air One worked closely with Lufthansa, almost all flights ran as codeshares, and there were partnerships with other Star Alliance airlines. In 2006 Air One announced it was preparing to join the alliance. Because of the merger with Alitalia, which belonged to SkyTeam, it never happened.
Why did Air One fly so many Boeing 737s?
In the 1990s the 737 was readily available on the leasing market and suited domestic routes like Rome–Milan. Air One flew the 737-200, 737-300, 737-400 and briefly the 737-800 in succession. In 2006 the switch to the Airbus A320 began, which replaced the 737 by 2010.
Is Air One the same as Alitalia?
No, not originally. Until 2008 Air One was an independent competitor. Only at Alitalia’s restart on January 13, 2009 did the new Alitalia – Compagnia Aerea Italiana also take over Air One. From 2010 Air One was then an Alitalia subsidiary with its own low-cost brand.
What was Air One “Smart Carrier”?
Under this name Alitalia launched a low-cost brand on March 28, 2010, initially with five Airbus A320s of 180 seats each from Milan Malpensa. Bases in Pisa, Venice, Catania and Palermo were added later. In October 2014 this flight operation ended as well.
Did Air One also fly long-haul?
Yes, briefly. In June 2008 Air One started flights from Milan Malpensa to Boston and Chicago with two Airbus A330-200s. Because of the merger with Alitalia it remained a short episode; an order for A330s and A350s also passed to Alitalia.
Are former Air One aircraft still flying?
Some A320s from the Air One era kept flying after 2014 with Alitalia and later with ITA Airways. According to a 2023 report, the last recognizable example was repainted in ITA colors at that time. You can trace an aircraft’s history through its registration.

Aircraft types in the fleet
Boeing 737-300
Fat engines with flat bottoms, a stretched fuselage and a new cockpit: with the 737-300, Boeing got the 737 ready for a second career in the mid-1980s. Here you learn where it came from, who flew it in Germany and where you can still find it today.
Aircraft typeBoeing 737-400
Three meters longer than the -300, two overwing exits and a tail skid under the rear fuselage: the 737-400 was Boeing’s answer to packed leisure flights. Here you read how it came about, who flew it in Europe and where you find it today as a freighter.
Aircraft typeBoeing 737-200
Slim cigar-shaped engines under the wing, a deflector behind the nose wheel and air nozzles ahead of the inlets: the 737-200 is the jet that lands on gravel. Here you will learn how the -200 and the -200 Advanced came about, how to recognize them and where they still fly today.
Aircraft typeAirbus A320 (ceo)
The jet with which Airbus turned the short-haul market upside down: the first-generation A320 has been in service since 1988 and is still seen at almost every airport. Here is how to recognize it and its variants.
Aircraft typeAirbus A330-200
Shorter than the A330-300, with a strikingly tall vertical stabilizer and long range: the A330-200 is a long-haul classic that is slowly disappearing from Europe’s fleets. Here is how to spot it with confidence.
Aircraft typeBombardier CRJ900
Slim fuselage, engines at the rear, T-tail on top: for years the CRJ900 was the workhorse of Lufthansa’s feeder traffic. Since CityLine’s demise it has become rare in Germany – here’s how to reliably spot it anyway.
Aircraft typeAvro RJ70
The Avro RJ70 is the modernized version of the BAe 146-100 – same short fuselage, new engines, digital cockpit. With only twelve built, it is the rarest production member of the whole Jumbolino family.
