How to recognize the airline
Is that really easyJet Switzerland?
- Orange tail and “easyJet” titles – looks just like the British parent
- Swiss registration starting with HB- instead of G- (easyJet UK) or OE- (easyJet Europe)
- On trackers the flight shows up as EZS, and on the radio it is “TOPSWISS”
- Almost always an Airbus A320 – with or without sharklets – or an A320neo
- Most common in Geneva and at EuroAirport Basel-Mulhouse, where the aircraft are based
- Some A320neos wear a special livery, such as one with “NEO” lettering or a Basel-Mulhouse design
An orange A320 taxis to the runway in Geneva – to most people that is just easyJet. For you as a spotter, a second look is worth it: behind the familiar livery there is often not the British parent but easyJet Switzerland, an independent Swiss airline with its own codes, its own callsign and Swiss registrations. This page shows you how to identify it reliably, where to see it best and why it exists at all.

easyJet Switzerland at a glance
easyJet Switzerland SA is a Swiss low-cost airline headquartered in Meyrin, right at Geneva Airport. It belongs to the group of British easyJet and operates as its franchise partner. It has no brand identity of its own: flights are sold through easyJet, the aircraft wear the familiar orange livery, and in the terminal the display simply says “easyJet.”
Its roots reach back further than the name. In 1988, the charter airline TEA Switzerland was founded in Switzerland, initially also operating as TEA Basel and flying from 1989. In the late 1990s easyJet took a stake, shortly afterward the company was renamed easyJet Switzerland and gradually integrated into the low-cost network. The company headquarters moved to Geneva.
Today easyJet Switzerland is the airline you see most often at Geneva and Basel-Mulhouse airports. Unlike SWISS, it has no hub for connecting passengers and does not belong to any alliance – it links western Switzerland and the Basel region with destinations all over Europe and around the Mediterranean.
Why there is a Swiss easyJet
The answer is a matter of traffic rights. Switzerland is not a member of the European Union. A British or Austrian airline is not automatically allowed to fly every destination from Swiss airports – especially on routes to countries outside the EU, you need an airline with a Swiss license. That is exactly why the group keeps its own company with a Swiss air operator certificate in easyJet Switzerland.
The rest of the group works in a very similar way: after Brexit, easyJet founded easyJet Europe in Austria so that the airline can keep flying freely within the EU. For you this means that behind the easyJet brand there are now three companies with three home countries – and three different registration prefixes.
| Company | Headquarters | IATA | ICAO | Callsign | Registration |
|---|---|---|---|---|---|
| easyJet UK | United Kingdom | U2 | EZY | EASY | G- |
| easyJet Europe | Austria | EC (sold as U2) | EJU | ALPINE | OE- |
| easyJet Switzerland | Switzerland | DS | EZS | TOPSWISS | HB- |
How country codes on the fuselage are built is explained in the article on country codes on aircraft. And why flight number and callsign are not the same thing, you can read in Callsign and flight number – the difference.
Reading trackers correctly
Flight trackers mostly show the ICAO code. If EZS shows up for an orange A320, the Swiss company is flying – even when you see it in London or Barcelona. More in the guide to flight tracking for spotters.
Codes and callsign
- IATA code DS: the IATA identifier of the Swiss company. In sales and on the booking page, however, it usually appears simply as easyJet.
- ICAO code EZS: appears in the flight plan filed with air traffic control and therefore on trackers. It is the most reliable hint to the Swiss company.
- Callsign TOPSWISS: this is how the crew checks in on the radio. If you follow radio traffic at your spot, you will immediately hear the difference from “EASY” (easyJet UK). What the law says about that is explained in the article Listening to airband radio – the legal situation.
The three identifiers do not obviously fit together – DS has nothing to do with “easy” or with Switzerland. That is normal: IATA and ICAO codes are pure assignments and often reflect an airline’s history. You get an overview of the system in the article IATA and ICAO codes explained.
The fleet: A320 and A320neo
easyJet Switzerland flies only aircraft of the Airbus A320 family. According to publicly available fleet lists (as of 2026), there are around 30 aircraft, split between the bases in Geneva and Basel-Mulhouse.
| Type | Status | Seats | Spotter note |
|---|---|---|---|
| Airbus A320 (A320ceo) | Majority of the fleet | 186 | Backbone of the fleet; some with sharklets, some with the small wingtip fences |
| Airbus A320neo | Growing share since 2021 | 186 | Much larger engines, always with sharklets |
| Airbus A319 | Retired since 2023 | – | Only in old logbooks with HB- registrations |
| Boeing 737-300 | Historic | – | Legacy of the TEA era, long since replaced |
The first-generation Airbus A320 is the workhorse. Interesting for you: not all Swiss A320ceos look alike. Some carry the upswept sharklets at the wingtips, others still have the small, triangular wingtip fences. That lets you collect two variants of the same type.
The Airbus A320neo has been joining since 2021. The group as a whole is switching its fleet to the neo generation, and in Switzerland too its share is growing step by step. The A319, on the other hand, has disappeared from the Swiss fleet. Elsewhere in the group, the larger A321neo also flies – at Swiss airports you are most likely to meet it on flights by easyJet UK or easyJet Europe.
Still missing the A320neo with an HB- registration?
Put it on your wish list in Planetrack and set up sighting alerts for registrations, types or special liveries – so you find out when they approach or land near you. Planetrack is launching soon – join the waitlist.
A320ceo or A320neo? How to tell them apart
At easyJet Switzerland, both generations wear the same livery and have the same seat count. The differences are in the details.
What points to the A320neo
- Very large, round engines that reach almost to the ground
- Always sharklets at the wingtips
- Listed as A20N on trackers
- Some aircraft with large “NEO” lettering on the fuselage
What points to the A320ceo
- Slimmer engines with more ground clearance
- Either sharklets or small wingtip fences
- Listed as A320 on trackers
- The majority of the Swiss fleet
Important: sharklets alone are not a reliable neo feature, because many A320ceos were also delivered with them. Rely on the engines – they are easy to recognize on approach and from a greater distance as well. You will find more tips on identifying types in the article Identifying aircraft types for beginners.
How to recognize easyJet Switzerland
The livery is identical to that of the rest of the group: white fuselage, orange “easyJet” titles and an orange tail. If you only photograph the tail, you therefore cannot tell the Swiss company from the British or Austrian one. Three things are decisive:
Check the livery
Orange tail and orange lettering – that tells you it is an easyJet.
Read the registration
HB- stands for Switzerland, G- for the United Kingdom, OE- for Austria. The prefix decides.
Cross-check the tracker
EZS confirms the Swiss company, EZY the British one, EJU easyJet Europe.
Log it cleanly
Record company, registration and type separately. That keeps the sighting unambiguous even years later.
A few Swiss A320neos stand out from the rest. Since late 2021, some aircraft have worn a variant with large “NEO” lettering, and since December 2024 an A320neo has been flying with a design dedicated to EuroAirport Basel-Mulhouse. Such deviations are the most sought-after designs in the fleet – how to hunt for them is covered in the article Finding special liveries.
Watch out for mix-ups
Many easyJet flights to Geneva and Basel are not operated by the Swiss company but by easyJet UK or easyJet Europe. A photo without a legible registration will hardly help you sort things out later. So always take a shot in which the registration is visible. How registrations are built is explained in the article Understanding aircraft registrations.
Spotting easyJet Switzerland
Geneva
Geneva Airport is the main base and the place where you are guaranteed to see easyJet Switzerland. The group’s orange jets shape a large part of the traffic here, and in the morning the aircraft parked overnight depart in quick succession. Geneva has only one major runway, and the runway direction in use depends mainly on the wind. An official view of the apron is offered by the observation deck at Geneva Airport. Check the current opening hours before you visit.
Basel-Mulhouse
EuroAirport Basel-Mulhouse-Freiburg is the second base. It lies on French soil but is operated jointly by France and Switzerland and has a Swiss and a French sector. It is easy to reach for spotters from southern Germany, and easyJet is the dominant airline here. One highlight is the A320neo with the Basel-Mulhouse design, which naturally shows up especially often here.
Zurich and Germany
easyJet Switzerland is not based in Zurich. easyJet does fly to Zurich Airport, but the orange aircraft there do not necessarily belong to the Swiss company. From Observation Deck B or from the Butzenbüel, it is therefore worth checking the registration. In Germany you mostly come across Swiss easyJets on routes from Geneva and Basel, for example to Berlin or Hamburg. The schedule changes regularly, though.
Good chances of easyJet Switzerland if …
- you are spotting in Geneva or at EuroAirport Basel-Mulhouse
- you are there early in the morning, when the based aircraft depart
- flights with the EZS identifier show up on the tracker
Check beforehand if …
- you are spotting in Zurich or at a German airport
- you are planning based on older spotter reports
Probably not a Swiss easyJet day if …
- your airport has no connection to Geneva or Basel
For good photos, the light matters as much as the schedule. How to plan the sun position at your spot is shown in the guide Planning the sun position at your photo spot. If you want to estimate the runway direction in advance, Understanding the runway direction in use at an airport will help.
Safety and rules
Only take photos from publicly accessible areas. Fences, barriers and security areas are off limits, and drones have no business near airports. What the law says is explained in the article Is plane spotting allowed?.
easyJet Switzerland and the other Swiss airlines
In Swiss aviation, every airline has its own role. SWISS is the network carrier with a hub in Zurich and belongs to the Lufthansa Group. Edelweiss flies leisure destinations, Helvetic Airways flies Embraer jets, often on behalf of SWISS, and Chair Airlines operates in the vacation and charter business. easyJet Switzerland is the low-cost carrier among them – and the only one whose aircraft you recognize by their orange color.
The big competitors in the European low-cost market are Ryanair and Wizz Air. Comparing types helps with quick pre-sorting: Ryanair flies almost only Boeing 737s, while easyJet and Wizz Air rely on Airbus.
Common mix-ups
- Taking every orange A320 for easyJet Switzerland – easyJet UK and easyJet Europe wear the same livery. The registration decides.
- Taking DS for a Swiss country code – DS is purely an airline identifier; the Swiss registration prefix is HB-.
- Taking sharklets as a reliable neo feature – many Swiss A320ceos have sharklets too. The engines are the more reliable feature.
- Automatically logging easyJet in Zurich as the Swiss company – easyJet Switzerland is not based there.
- Taking EuroAirport for a purely Swiss airport – it is located in France and operated binationally.
- Equating the flight number with the operating company – the ICAO code on the tracker shows who is really flying.
Keep an eye on easyJet Switzerland
Follow individual HB- registrations or the neo special liveries, get notified on approach or landing, and post your sighting with type, registration, airline and spot. Planetrack is launching soon – join the waitlist and get early access.
Conclusion
easyJet Switzerland is an airline that hides behind a well-known brand. If you only look at the color, you see “easyJet.” If you look at the registration, you find an independent Swiss company with roots going back to 1988, bases in Geneva and Basel and a fleet in transition from the A320ceo to the A320neo. With the HB- prefix, EZS on the tracker and “TOPSWISS” on the radio, you can assign every sighting with confidence.
In short
easyJet Switzerland (IATA DS, ICAO EZS) is the Swiss low-cost company in the easyJet group with bases in Geneva and Basel-Mulhouse. The livery is the same as the parent’s – the HB- registration gives away the Swiss origin.
Summary
- easyJet Switzerland looks like any other easyJet – you can only tell it apart by the registration, ICAO code and callsign.
- An HB- on the fuselage of an orange A320 gives away the Swiss company, and on the tracker EZS confirms it.
- Geneva and Basel-Mulhouse are where you will see the most of it. There, easyJet Switzerland is one of the most important airlines of all.
- The fleet is gradually being switched to the A320neo – A320ceos with HB- registrations are therefore collectibles on borrowed time.
Frequently asked questions
What are easyJet Switzerland’s IATA and ICAO codes?
The IATA code is DS and the ICAO code is EZS. On the radio, the crew uses the callsign “TOPSWISS.” British easyJet, by contrast, uses U2, EZY and “EASY,” and easyJet Europe uses the ICAO code EJU.
Is easyJet Switzerland a separate airline?
Yes. easyJet Switzerland SA is an independent Swiss airline with its own air operator certificate and headquarters in Meyrin near Geneva. It operates as a franchise partner under the easyJet brand and is closely tied to the group. You can only book its flights through easyJet.
Why is there a Swiss easyJet?
Because of traffic rights. Switzerland is not a member of the EU. For easyJet to serve destinations from Switzerland that require a Swiss airline, the group needs a company with a Swiss license. easyJet Switzerland fills that role.
Which aircraft does easyJet Switzerland fly?
Only aircraft of the Airbus A320 family. According to publicly available fleet lists, there are around 30 aircraft, mostly first-generation A320s (A320ceo) with 186 seats and a smaller, growing number of A320neos. The A319s used earlier have not been part of the Swiss fleet since 2023. It is best to check the current status before your trip.
Where are easyJet Switzerland’s bases?
In Geneva (GVA) and at EuroAirport Basel-Mulhouse-Freiburg (BSL). The company headquarters is in Geneva as well. easyJet does fly to Zurich, but there is no Swiss base there.
How can I tell whether an easyJet comes from Switzerland?
By the registration: Swiss aircraft carry HB-, British ones G- and Austrian ones OE-. On the tracker, the ICAO code helps: EZS stands for Switzerland, EZY for the UK, EJU for easyJet Europe. The livery is the same on all of them.
Is easyJet Switzerland part of an alliance?
No. Like the entire easyJet group, the Swiss company is not in Star Alliance, oneworld or SkyTeam. It focuses on direct flights without a partner network.

Where to get easyJet Switzerland in front of your lens
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.
Observation deckObservation Deck B at Zurich Airport
On the roof of Dock B you stand in the middle of the action at Switzerland’s largest airport: SWISS long-haul, taxiing traffic right below you and heavy takeoffs on the longest runway. Probably Switzerland’s best-known legal spotting place – with security screening, admission and clear rules.
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.
