Smartwings

When a Boeing 737 with an OK- registration shows up at the airport, chances are high that Smartwings is behind it. The Czech airline is no everyday guest in Germany, and that is exactly what makes it interesting: it often comes as a charter, as a stand-in for other airlines or even dressed in the livery of an entirely different brand. On this page you will learn how to identify Smartwings reliably – from the ICAO code to the subsidiaries to the Airbuses in Czech Airlines colors.

Smartwings at a glance

Smartwings is the Czech Republic’s largest airline and is based right at Prague Airport. It started in 1997 under the name Travel Service – as a charter airline that flew vacationers to the Mediterranean on behalf of Czech tour operators. The first aircraft was a Tupolev Tu-154M, Boeing 737s joined from 2000, and the 737 has been the defining type of the fleet ever since.

In 2004, Travel Service founded Smart Wings as a brand of its own for low-fare scheduled flights. For years, both names ran in parallel: Travel Service for charter, Smart Wings for scheduled service. In 2018, the airline cleaned house: the Travel Service livery gradually gave way to the Smartwings paint scheme, and in December 2018 the company name changed too. Since then, there has been only Smartwings.

Today, Smartwings combines both: package-holiday charters, its own scheduled routes from Prague and the leasing of aircraft with crew to other airlines. For summer 2026, the trade portal planes.cz reported around 80 direct destinations from Prague. There are also departures from other Czech airports, such as Brno, Ostrava or Pardubice.

Codes and callsign

• IATA code QS: appears in the flight number on departure boards and tickets.
• ICAO code TVS: appears in the air traffic control flight plan and on most flight trackers.
• Callsign SKYTRAVEL: how the crew identifies itself on the radio.

The ICAO code TVS and the callsign are leftovers from the Travel Service days – the name changed, the identifiers did not. If you haven’t quite sorted out the difference between flight number and callsign yet, you’ll find it explained in the article Callsign and flight number; the logic behind the codes is in IATA and ICAO codes explained.

Smartwings and Czech Airlines

For spotters, the connection to Czech Airlines (ČSA) is the most confusing part of the story. Travel Service bought into the venerable state airline in 2015 and became its majority owner in 2017. At the end of October 2024, Czech Airlines then ceased its own flight operations – after more than 100 years. Smartwings took over the flights, and Czech Airlines remained as a holding company.

The brand has not disappeared, though. The group’s Airbus A220-300s and at least one A320 continue to fly in Czech Airlines livery. The operator, however, is Smartwings. For your logbook, that means: livery “Czech Airlines”, operator “Smartwings” – log the two separately, or your statistics won’t add up later.

Since October 2026: part of the Pegasus group

In 2025, there was a veritable bidding race for Smartwings. At times, LOT Polish Airlines was considered the favorite, but in the end the Turkish low-cost carrier Pegasus Airlines prevailed. In December 2025, Pegasus agreed to buy Czech Airlines and the Smartwings group; the acquisition was completed as of October 1, 2026. Since then, two managers from Pegasus headquarters have run Smartwings as CEO and CFO.

According to reports on the acquisition, Smartwings remains an independent brand – in the Czech market and in the charter business. What this means for the fleet and livery in the long run is open. For spotters, it is therefore worth documenting the Smartwings fleet as it is now.

The fleet: Boeing 737s plus a few Airbuses

Fleet numbers fluctuate more at Smartwings than at many other airlines because aircraft are repeatedly leased out to partners. The following overview is based on the fleet figures from planes.cz for the summer 2026 schedule; the sister company’s business jets are not counted.

Type	Number	Livery	Spotter tip
Boeing 737-800	23	Smartwings	Backbone of the fleet, registrations often OK-TV… or OK-TS…
Boeing 737 MAX 8	13	Smartwings	Registrations mostly OK-SW…, often out on wet lease
Boeing 737-900ER	2	Smartwings	Longest 737 in the fleet, rare
Airbus A220-300	4	Czech Airlines	Smallest type in the fleet, 149 seats
Airbus A320	2	Czech Airlines (at least one)	First-generation A320

The Boeing 737-800 is the workhorse. Joining it is the Boeing 737 MAX 8: in early 2018, Smartwings was among the first operators worldwide. After the worldwide grounding, it put its MAX back into service in 2021 as the first European airline. The two 737-900ERs are much longer than the 737-800 – a nice catch if you manage to get them.

On the Airbus side, there is the A220-300, built by Airbus, plus the classic Airbus A320. The A220 and at least one A320 wear Czech Airlines colors. How to tell the two manufacturers apart even from a distance is shown in the guide Telling Airbus and Boeing apart.

737-800 or 737 MAX 8? How to tell them apart

At Smartwings, both generations wear the same livery. A few details still reveal which one you are looking at.

The engines are the most reliable clue: you can see the serrated trailing edges of the MAX engines well even on approach if you shoot from the side with a telephoto lens. The registration series are a good hint but no guarantee – aircraft sometimes change registration when they are moved between companies of the group.

One brand, several airlines: the subsidiaries

As with many European leisure airlines, Smartwings has offshoots in neighboring countries. They originated as Travel Service Hungary, Slovakia and Polska and today carry the Smartwings name.

Airline	Headquarters / bases	IATA	ICAO	Callsign	Registration
Smartwings	Prague	QS	TVS	SKYTRAVEL	OK-
Smartwings Poland	Katowice, Warsaw	3Z	TVP	JETTRAVEL	SP-
Smartwings Slovakia	Bratislava, Košice	6D	TVQ	SLOVAKTRAVEL	OM-
Smartwings Hungary	Budapest, Debrecen	7O	TVL	TRAVEL SERVICE	HA-

The subsidiaries have only a few aircraft of their own and bring in 737s from Prague when needed. A Smartwings Hungary flight can therefore well be operated by an OK-registered aircraft. In Budapest, you can watch them, for example, from the Aeropark at Budapest Airport, in Warsaw at Chopin Airport. Which country code belongs to which state is listed in the overview of country codes on aircraft.

Wet lease: Smartwings on assignment for others

A large part of the business consists of leasing aircraft with crew to other airlines. According to planes.cz, several Smartwings 737s were deployed with airlines in Saudi Arabia, Cameroon and India in 2026, a 737 MAX 8 flew for Air Seychelles in February, and a MAX briefly helped out at Cabo Verde Airlines. Smartwings also stepped in in Europe: in 2024, Boeing 737-800s flew for Eurowings in a mixed livery of both brands.

For spotters, such assignments are a treat. A Czech registration under another airline’s flight number fits no pattern – and that is exactly why a second look is worthwhile. How the model works is explained in the article Wet lease explained.

A charter announced for March and April 2026 was also out of the ordinary: a trip around the world from Prague on a 737 MAX 8 with a converted cabin. Such one-off flights hardly ever appear in the regular flight schedule – trackers and the spotter community help here.

Spotting Smartwings in Germany

In the scheduled timetable of German airports, Smartwings plays only a minor role. The airline comes more often as a charter: in March 2025, for example, several Smartwings 737s stood in Düsseldorf at the same time because a car manufacturer had chartered flights. Then there are codeshares with Eurowings. You can therefore spot Smartwings more spontaneously than on a plan – at Düsseldorf Airport as well as at vacation airports.

If you want to see Smartwings specifically, Prague is the safe address. There, the airline is the biggest user, and besides the 737s you also see the A220 in Czech Airlines colors. Compare the Smartwings fleet there with other leisure and low-cost carriers in the region such as Enter Air or Wizz Air: Enter Air also flies 737s, Wizz Air flies Airbus.

Before you set off, take a look at the wind and runway direction in use – the guide to the runway direction in use at airports helps with that. If you are new to this, Plane spotting for beginners gives you a good start.

Common mix-ups

• Taking a ČSA Airbus for a Czech Airlines operation – since the end of 2024, Smartwings flies these aircraft.
• Taking TVS for a foreign code – it is simply Smartwings, a leftover from the old name Travel Service.
• Assuming every OK- 737 is Smartwings – usually true, but on wet lease it flies under another airline’s flight number.
• Overlooking the subsidiaries – SP-, OM- or HA- registrations and the codes TVP, TVQ and TVL also belong to the group.
• Equating Smartwings with Pegasus – Pegasus has been the owner since October 2026, but Smartwings continues to fly under its own brand.
• Logging the A320 as an A320neo – the group flies the first-generation A320 with smaller engines.

Conclusion

Smartwings is more than a Czech leisure airline. Behind the name are the old Travel Service, the flight operations of Czech Airlines, three subsidiaries in neighboring countries and a fleet that regularly flies for other airlines. Since October 2026, the whole thing belongs to Pegasus. Anyone who logs registration, ICAO code and livery separately keeps track – and instantly recognizes the rare Smartwings visitors in Germany.
