Key takeaways
- FlyArystan is the low-cost subsidiary of Air Astana and is considered Kazakhstan’s first budget airline.
- Codes: IATA FS, ICAO AYN – since January 2025 the airline flies under its own code instead of Air Astana’s.
- The fleet is a pure A320 family: first-generation A320s with 180 seats and A320neos with 188 seats.
- The name comes from the lion: “Arystan” is the Kazakh word for lion, and the lion’s head adorns the tail.
- FlyArystan does not fly to central Europe: you can spot it mainly in Kazakhstan and at destinations in Central Asia, the Caucasus, Turkey, China and the Gulf.

How to recognize the airline
Is that really FlyArystan?
- White tail with a large, red-drawn lion’s head
- A red area that rises from the belly toward the rear up to the tail, plus red engine nacelles with the web address
- “FlyArystan” titles: “Fly” in dark blue, “Arystan” in red
- Always an Airbus A320 or A320neo – the airline flies no other types
- Often Irish registrations with EI-, frequently in the series EI-KB…
- Small Kazakh flag at the front of the fuselage near the cockpit
If you stand at a Kazakh airport, you see two color worlds: Air Astana’s elegant design and, next to it, a red lion on a white tail. That lion belongs to FlyArystan, the group’s low-cost subsidiary. For spotters from central Europe it is a real travel catch, because it does not fly to Germany. Here you learn where the airline comes from, what is in its fleet and how to identify its aircraft reliably.

FlyArystan at a glance
FlyArystan is Kazakhstan’s first low-cost airline and belongs entirely to Air Astana. The idea was developed within the group in 2018, and in early November 2018 the shareholders of the time gave the green light. The aim was an affordable offering for the domestic market and neighboring regions.
Ticket sales began in late March 2019, and the first flight took off in Almaty on May 1, 2019. At the start just two Airbus A320s with 180 seats each were ready, serving mainly domestic routes from Almaty, such as to Astana, Karaganda, Shymkent or Pavlodar. The first international destinations were added the same year.
Since then FlyArystan has grown strongly. In 2023, according to reference works, the airline carried around 3.6 million passengers, roughly five times the 2019 figure. Air Astana and FlyArystan together reached around 9.7 million passengers in 2025. For its service the budget subsidiary has repeatedly been named best low-cost airline in Central Asia and the CIS at the Skytrax World Airline Awards.
From brand name to its own airline
In the early years FlyArystan was above all a brand. Flights ran under Air Astana’s air operator’s certificate (AOC) and under its code KC. Only step by step did it become an independent airline:
- October 2023: FlyArystan is registered as a separate company.
- April 2024: The Kazakh aviation authority grants the airline its own AOC. In fall 2024 its own IATA code FS is announced.
- January 1, 2025: All flights run under the code FS instead of KC, and ticket numbers have started with 164 instead of 465 ever since.
For spotters this change matters when you sort older photos and logbook entries. Flights before 2025 often still appear in schedules and on trackers with the Air Astana identifier. Since 2025 you recognize FlyArystan directly by FS in the flight number and AYN on the tracker.
In parallel the parent group also went public: Air Astana was listed in February 2024 in London, on the Astana International Exchange and on the Kazakh stock exchange. FlyArystan remained part of the group. How such two-brand models of network airline and budget subsidiary work is explained in the article on airline multi-brand strategies.
Reading the tracker correctly
Flight trackers usually show the ICAO code. If AYN appears for a red-and-white A320, FlyArystan is flying; KZR, by contrast, stands for Air Astana. How to make sensible use of ADS-B data at the spot is shown in the guide to flight tracking for spotters.
The fleet: a pure A320 family
People often speak of an A320neo fleet, but that is only half true: FlyArystan flies two generations of the A320 side by side. According to the fleet status as of summer 2026, it looks like this:
| Type | Count | Seats | Origin | Spotter note |
|---|---|---|---|---|
| Airbus A320 (first generation) | 15 | 180 | partly taken over from Air Astana | Smaller engines, wingtip fences or sharklets depending on the aircraft |
| Airbus A320neo | 13 | 188 | younger generation of the fleet | Large engines, always sharklets |
| Airbus A320neo | 1 on order | 188 | – | Further growth within the family |
All aircraft are single-class with economy seating – typical for a budget airline that wants to fit as many seats as possible into the cabin. A letter of intent for 30 Boeing 737 MAX 8s signed in 2019 was never converted into a firm order. For you that means: there is no Boeing in FlyArystan colors.
The Airbus A320 is the backbone from the start-up phase. With the Airbus A320neo came eight additional seats and newer engines. Both types come from Airbus. One peculiarity you often do not see in photos: the aircraft carry names of stars and constellations, such as Leo, Orion, Sirius, Polaris, Vega or Rigel. Passengers were able to take part in choosing the names. You find more on such christening names in the article on aircraft names at airlines.

A320 or A320neo? How to tell them apart
Because both generations wear the same livery, a look at the technology decides. The most important features compared:
Points to the A320neo
- Clearly larger, almost round engine nacelles that sit farther forward of the wing
- Tall sharklets at the wingtips
- Listed as A20N on trackers
- Mostly the younger aircraft in the fleet
Points to the A320 (ceo)
- Slimmer, smaller engine nacelles
- Small wingtip fences – or sharklets on younger examples
- Listed as A320 on trackers
- Partly aircraft that previously flew for Air Astana
Important: sharklets alone are not a reliable neo feature, because later first-generation A320s were also built with them. The most reliable clue is the diameter of the engines. How to tell the variants apart step by step is explained in the guides A320neo or ceo? and Winglets, sharklets and more.
How to recognize FlyArystan
The livery is one of the most striking in Central Asia. The fuselage is predominantly white. From the underside a red area runs toward the rear and rises up to the base of the tail, while the tail end below stays white. The tail itself is white and carries a large, stylized lion’s head in red.
The lion is no coincidence: “Arystan” means lion in Kazakh. The “FlyArystan” titles run large across the front fuselage, with “Fly” set in dark blue and “Arystan” in red. The engine nacelles are red and carry the airline’s web address. Near the cockpit you find a small Kazakh flag.
By comparison Air Astana looks much more restrained and relies on an entirely different color world. If you see both airlines on the same apron, you will hardly mix them up – FlyArystan’s red belly can be recognized from a great distance.
Careful with the registration
Many FlyArystan aircraft are registered in Ireland. Documented in photos are, for example, A320s such as EI-KBA, EI-KBD or EI-KBN and A320neos such as EI-KBP or EI-KBR. An EI- on the tail therefore does not mean “Irish airline” here. Why leased aircraft often use foreign registers is explained in the article on aircraft leasing.
Check the tail
Red lion’s head on white – that settles the airline.
Determine the generation
Engine size and wingtips reveal whether it is an A320 or A320neo.
Read the registration
Mostly EI-KB… – only the registration makes the sighting unambiguous.
Cross-check the tracker
The ICAO code AYN confirms that FlyArystan itself is flying.
How registrations are structured and what the prefixes reveal is shown in the basic article Understanding aircraft registrations. If you want to collect individual aircraft deliberately, the guide Tracking an aircraft by registration helps.
Network and bases
FlyArystan is headquartered in Almaty, which is also where the most important base is. A second focus is the capital Astana. In addition, the airline stations aircraft at further airports in the country; depending on source and time, Aktau, Atyrau, Shymkent or Karaganda are named. With budget airlines such stationings change quickly.
In May 2026 the network comprised 24 destinations according to reference works, 14 of them domestic and 10 international. Domestically FlyArystan connects the big cities with regional centers such as Kyzylorda or Turkestan – in a country of this size the aircraft often replaces long train or car journeys. Internationally, most recent destinations included:
- Central Asia: Uzbekistan (such as Tashkent and Samarkand) and Kyrgyzstan (such as Bishkek)
- Caucasus: Georgia, Armenia and Azerbaijan
- China: several cities in the west and interior of the country
- Turkey and the Gulf: including Istanbul and Dubai
Always check the current schedule for which routes are running right now. The business model behind it – uniform fleet, dense seating, short turnaround times – is described in the article How low-cost carriers work.
Spotting FlyArystan
Because the airline does not fly to central Europe, you need a trip for FlyArystan. Almaty is the most productive: this is where the airline has its largest presence, and you see it alongside Air Astana and many visitors from Central Asia, China and Turkey. Astana is worthwhile too, mainly for domestic flights.
Outside Kazakhstan you can catch the red lions at destination airports. In Istanbul or Dubai, though, FlyArystan is just one guest among hundreds – there you need luck or a look at the schedule. You find similar low-cost concepts with an Airbus fleet at Wizz Air and Pegasus Airlines; in Dubai, flydubai with Boeing 737s is the local budget carrier. In Central Asia, Uzbekistan Airways is a frequent neighbor.
Good chances of FlyArystan if …
- you spot in Almaty or Astana
- you are there early in the morning when the based aircraft start their first rotations
- FS flights are in the current schedule at your destination airport
Check beforehand if …
- you are waiting for a single flight at a big hub outside Kazakhstan
- you plan from older travel reports – routes and bases change
Not a FlyArystan day if …
- you are at an airport in Germany, Austria or Switzerland
Photographing abroad
Rules on photographing at airports differ from country to country. Find out before your trip, stay in publicly accessible areas and do not photograph security installations. An overview of the situation in Germany is given in the article Is plane spotting allowed?.
Common mix-ups
- Taking FlyArystan for Air Astana – both belong to the same group but have completely different liveries and their own codes.
- Assigning older flights incorrectly – until the end of 2024 FlyArystan flew under Air Astana’s code KC.
- Reading EI- registrations as an Irish airline – the aircraft are registered in Ireland, but the airline is based in Almaty.
- Logging every A320 with sharklets as a neo – younger first-generation A320s have sharklets too; the engines decide.
- Looking for a Boeing – the 2019 737 MAX letter of intent was never carried out.
- Taking “Arystan” for a place name – the name means lion.

Conclusion
In a few years FlyArystan has gone from a brand with two aircraft to an independent airline with almost 30 aircraft. For spotters it is rewarding and demanding at the same time: the red lion makes the airline unmistakable, but the real work begins with telling the A320 and A320neo apart and reading the Irish registrations. If you travel to Almaty or Astana, you cannot miss it.
In short
FlyArystan (IATA FS, ICAO AYN) is Air Astana’s Kazakh low-cost subsidiary with a pure fleet of A320s and A320neos. You recognize the red lion’s head on the tail instantly; only a look at the engines reveals the generation.
Summary
- You recognize FlyArystan immediately by the red lion’s head on the white tail and the red arc running from the belly to the tail.
- The fleet consists only of A320s and A320neos – the real spotter challenge is telling the two generations apart by the engines and wingtips.
- Many aircraft carry Irish EI- registrations even though the airline is from Kazakhstan; that is common for leased aircraft in the region.
- For spotters from Germany, FlyArystan is a classic travel target: you see the most traffic in Almaty and Astana.
Frequently asked questions
What are FlyArystan’s IATA and ICAO codes?
FlyArystan uses the IATA code FS and the ICAO code AYN. At first the airline flew under Air Astana’s operating certificate and, until the end of 2024, under its code KC. After receiving its own air operator’s certificate in 2024, it got its own code, under which FlyArystan has flown since January 1, 2025.
Does FlyArystan belong to Air Astana?
Yes. FlyArystan was founded at the end of 2018 as a low-cost brand within Air Astana and is a 100% subsidiary. It has been registered as a separate company since 2023 and has had its own operating certificate since 2024. Together with Air Astana it forms the Air Astana Group.
Which aircraft does FlyArystan fly?
Airbus A320s only. In summer 2026 the fleet comprised 28 aircraft: 15 first-generation A320s with 180 seats, some of them taken over from Air Astana, and 13 A320neos with 188 seats. A further A320neo was on the order list. All aircraft are single-class with economy seating.
What does the name Arystan mean?
“Arystan” is the Kazakh word for lion. That is why the tail shows a large red lion’s head. Fittingly, the aircraft carry names of stars and constellations, for example Leo, Orion, Sirius or Vega.
Does FlyArystan fly to Germany?
No. FlyArystan flies mainly within Kazakhstan and to neighboring regions, such as Uzbekistan, Kyrgyzstan, Georgia, Armenia, Azerbaijan, China, Turkey and the Gulf. In Germany, Austria and Switzerland you do not see the airline in regular scheduled service.
Where is the best place to spot FlyArystan?
Almaty has the most FlyArystan traffic, as the airline is headquartered and has its main base there. Many flights can also be seen in Astana, as well as at regional airports such as Aktau, Atyrau or Shymkent. Outside Kazakhstan the red lions show up at destinations such as Tashkent, Bishkek, Batumi, Yerevan, Istanbul or Dubai – depending on the current schedule.
Why do FlyArystan aircraft have Irish registrations?
Many aircraft in the fleet are registered in Ireland and carry registrations with EI-, for example from the series EI-KB…. This is not unusual for leased aircraft: another country’s register is chosen because it is practical for lessors and financing. So you cannot tell from the registration alone that a Kazakh airline is flying.
Is FlyArystan a member of an alliance?
No. Like most low-cost airlines, FlyArystan does not belong to an alliance. It is connected through a codeshare agreement with its group sister Air Astana.
