Turkish Airlines

Turkish Airlines is one of the airlines you see almost everywhere in Central Europe: Frankfurt, Munich, Düsseldorf, Vienna, Zurich – the red tail with the round logo is on the schedule at practically every major airport. It gets exciting at second glance: TK flies Airbus and Boeing, narrowbodies and widebodies, plus there is the low-cost subsidiary AJet and the freighters of Turkish Cargo. This page shows you how to keep it all cleanly apart.

Turkish Airlines at a glance

Turkish Airlines is Turkey’s network airline and one of the oldest airlines in Europe. It was founded on May 20, 1933, as the state-owned Devlet Hava Yolları – then a department of the Ministry of Defense with just five aircraft. In 1956 it received its current legal form as Türk Hava Yolları, or THY for short. That is also where the ICAO code comes from, which still appears on every tracker today.

Its history reads like a tour through aircraft type history: in 1967 a McDonnell Douglas DC-9 brought the first jet, in the 1980s the Airbus A310 followed, and from 1994 there were nonstop flights to New York. Today part of the shares is traded on the Istanbul stock exchange; the largest single shareholder is the Turkish sovereign wealth fund, with just under half of the shares.

Since April 1, 2008, Turkish Airlines has been a member of Star Alliance – the same alliance as Lufthansa, SWISS and Austrian Airlines. The business model is classic: passengers from all over Europe, Africa, Asia and the Americas change planes in Istanbul. In December 2024 the airline received a Guinness World Record for the most countries served – 131 at the time.

Codes and callsign

• IATA code TK: appears in the flight number, on the departure board and on the ticket.
• ICAO code THY: appears in the air traffic control flight plan and on ADS-B trackers.
• Callsign TURKISH: this is how the crew identifies itself on the radio.

That the IATA and ICAO codes look so different is no coincidence: TK is a pure airline identifier, while THY is the abbreviation of the Turkish name. If you want to know why flight number and callsign are not the same thing, the article Callsign vs. flight number helps; the basics of the codes are explained in IATA and ICAO codes.

Hub Istanbul

The heart of the network is Istanbul Airport (IST) in the north of the city. The move there is one of the most spectacular logistics operations in recent aviation history: on April 6, 2019, the entire scheduled traffic switched within a single day from the old Atatürk Airport to the new site; hundreds of trucks carried the equipment over in an operation of a good 40 hours. The airport code IST moved along with it; the old airport lost it. Turkish Cargo followed with its complete cargo operations in early 2022.

The airline’s headquarters, incidentally, is still on the grounds of the old Atatürk Airport in Yeşilköy. The low-cost subsidiary AJet, by contrast, concentrates on Istanbul’s second airport, Sabiha Gökçen on the Asian side, as well as Ankara and Antalya.

For you as a spotter in Central Europe, the hub model means: departures to Istanbul are often timed so that passengers can connect there well. Many routes are served several times a day, and the rotation is usually a round trip from Istanbul. An aircraft that lands in Frankfurt in the morning is on its way back again after a short ground time.

The fleet: Airbus and Boeing mixed

Unlike many network airlines, Turkish Airlines consistently relies on two manufacturers. Both Airbus and Boeing supply narrowbodies and widebodies. According to fleet overviews from mid-2026, the passenger fleet excluding AJet comprises around 370 aircraft, and just under 390 with the freighters; the exact numbers shift with every delivery and return.

Type	Use	Spotter note
Airbus A319, A320	Short and medium haul	Smaller group, rather rare on routes to Germany
Airbus A321	Short and medium haul	For a long time the standard in Europe
Airbus A321neo	Short and medium haul	Growing strongly, large engines as a giveaway
Boeing 737-800, 737-900ER	Short and medium haul	The 900ER is the long classic with additional emergency exits
Boeing 737 MAX 8, MAX 9	Short and medium haul	Serrated nacelle trailing edges, split winglets
Airbus A330-200, A330-300	Medium and long haul	Turkish is one of the largest operators of the first-generation A330
Airbus A350-900	Long haul	Characteristic “raccoon mask” around the cockpit windows
Boeing 787-9	Long haul	Curved wings without classic winglets
Boeing 777-300ER	Long haul	The flagship: six-wheel landing gear, huge GE90 engines

Turkish Airlines is also big on the outlook. In 2023 the airline ordered around 220 Airbus aircraft, including A321neos, A350-900s, A350-1000s and A350F freighters. In September 2025 a firm order at Boeing for 787-9s and 787-10s followed; in addition the airline announced a large order for 737 MAXs. The A350-1000 is intended for particularly long routes. It will take a while, though, before these types in TK red turn up regularly in Europe – deliveries stretch over years.

Narrowbody or widebody? How to classify TK

On most routes to Germany, Austria and Switzerland, Turkish Airlines flies narrowbody aircraft. The interesting question is: Airbus or Boeing? At TK, an A321neo can arrive on the same route one day and a 737 MAX the next.

If you are unsure, the article Telling Airbus and Boeing apart helps. In Central Europe you see widebodies at Turkish Airlines mostly on high-demand routes or at peak times; the tracker usually tells you which type is on a particular flight hours in advance.

How to recognize Turkish Airlines

The livery is simple and works from a long distance precisely because of that: a white fuselage, dark blue “TURKISH AIRLINES” titles and a red tail with the round company logo. The logo shows a stylized wild goose – the motif comes from a design competition in 1959 and was later simplified. On the rear fuselage there is also a subtle gray ornamental element inspired by a tulip.

Special liveries are especially sought after. Turkish Airlines is heavily involved in sports sponsorship and has in the past painted aircraft with soccer and basketball motifs, among others. Such aircraft don’t appear on a fixed schedule – how to find them anyway is covered in the guide to special liveries.

Three brands, one group: TK, AJet and Turkish Cargo

Several brands fly under the umbrella of Turkish Airlines. For passengers this blurs; for spotters a clean separation is worthwhile.

Brand	IATA	ICAO	Callsign	Focus
Turkish Airlines	TK	THY	TURKISH	Network via Istanbul (IST)
AJet	VF	TKJ	ANATOLIA	Low-cost from Sabiha Gökçen, Ankara and Antalya
Turkish Cargo	(under TK)	(under THY)	TURKISH	Cargo with A330-200F and 777F

AJet grew out of the AnadoluJet brand, which Turkish Airlines had founded in 2008 for domestic and regional traffic. The company was established as a separate entity in July 2023, Turkish Airlines presented the new design at the end of 2023, the company’s own air operator certificate came in early 2024, and since April 1, 2024, the subsidiary has flown under the name AJet. The fleet consists of Airbus A320/A321s of both generations and Boeing 737-800s as well as 737 MAX 8s. AJet remains a wholly owned subsidiary.

Turkish Cargo operates its own freighters: the A330-200F, of which Turkish, according to fleet overviews, is one of the largest operators worldwide, and the Boeing 777F. Add to that cargo in the belly of the passenger aircraft. How to recognize freighters at the spot is explained in Identifying cargo aircraft.

SunExpress plays a special role: the leisure airline based in Antalya was founded in 1989 as a joint venture and is owned half each by Turkish Airlines and Lufthansa. More on the page for SunExpress. Competition on Turkey routes comes from Pegasus Airlines and Corendon Airlines.

Spotting Turkish Airlines in Germany, Austria and Switzerland

Hardly any foreign airline is as broadly represented in the German-speaking region. Turkish Airlines flies to Frankfurt, Munich, Düsseldorf, Berlin, Hamburg, Stuttgart, Cologne/Bonn, Hanover, Nuremberg and Bremen, among others. Add to that Vienna, Salzburg, Zurich and Geneva. One reason for the dense presence is the close ties between Turkey and people with Turkish roots in Central Europe; another is the many connecting passengers who fly on via Istanbul to Asia, Africa or the Middle East.

Good spots for TK are the big sites: in Frankfurt the Zeppelinheim viewing platform, in Munich the visitors’ hill, in Düsseldorf the observation deck, in Berlin the observation deck at BER, in Vienna the spotter hill and in Zurich observation deck B.

As always, the runway direction in use matters. If the wind is wrong, aircraft land at the other end of the airport and your spot ends up in backlight. How to estimate the direction in advance is shown in the guide to the runway direction in use at the airport; you can plan the right sun position with the article Sun position at your photo spot.

Turkish compared with other hub airlines

At the spot you often meet Turkish Airlines next to the big Gulf airlines. The difference lies in the network and the fleet: Emirates flies only widebodies, mainly the A380 and 777, while Qatar Airways mixes narrowbodies and widebodies. Turkish Airlines, by contrast, sends mostly narrowbodies to Central Europe – but on a great many routes. Anyone connecting via Istanbul therefore often starts on an A321neo or 737 MAX and only continues from the hub on a widebody.

Within Star Alliance, TK is the partner for connections toward the east and south. How the three big alliances work is explained in Star Alliance, oneworld, SkyTeam.

Common mix-ups

• Taking THY for a typo – THY is the correct ICAO code and stands for Türk Hava Yolları.
• Taking every red tail for Turkish – SWISS and Austrian also fly with red on the tail. Logo and registration decide.
• Logging AJet as Turkish Airlines – AJet is a separate airline with VF/TKJ and its own livery.
• Equating A321 and A321neo – the neo has much larger engines. More on that under Identifying aircraft types.
• Taking SunExpress for a pure Turkish subsidiary – SunExpress is owned half each by Turkish Airlines and Lufthansa.
• Naming the old Atatürk Airport as the hub – since April 2019, Istanbul (IST) in the north of the city has been the hub.

Conclusion

For spotters in the German-speaking region, Turkish Airlines is a regular with depth. Behind the red tail are a mixed Airbus-Boeing fleet, a hub with connections to more than 130 countries and, with AJet and Turkish Cargo, two brands of its own. If you log registration, type and ICAO code, you turn the next TK landing into a clean entry in your logbook.
