MIAT code added to Budapest-Istanbul flight: reaching Mongolia may be easier

From the beginning of June, MIAT Mongolian Airlines will appear in a codeshare agreement on Turkish Airlines' Istanbul-Budapest flights, which for Hungarian travelers may mean not a new direct flight, but more convenient booking and transfer options toward Mongolia, Ulaanbaatar, and the region. The change may be particularly interesting for those who would not only travel from Budapest to Istanbul, but would continue their journey toward the interior of Asia on a single ticket with more transparent airline cooperation.

According to recent schedule data from AeroRoutes, MIAT Mongolian Airlines expanded its partnership with Turkish Airlines in June 2026, and the codeshare now extends to the Turkish Airlines flight between Istanbul and Budapest. According to the post, code OM1033 is linked to the TK1037 Istanbul-Budapest flight, and code OM1034 is linked to the TK1038 Budapest-Istanbul flight. The flight continues to be operated by Turkish Airlines, meaning the passenger does not need to look for a separate MIAT aircraft in Budapest: the point is that the Mongolian airline can now sell or display this route segment with its own flight number.

At first glance, this may seem like technical news, but in travel planning, codesharing often makes a very practical difference. Such an agreement can help the Budapest-Istanbul-Ulaanbaatar route appear in a single booking process, the transfer fit better into airline systems, and baggage handling rules become more transparent. According to Turkish Airlines' own information, for codeshare flights, the operating airline is indicated during booking, on the ticket, in the confirmation, and at check-in, so it is worth checking the details separately before every trip.

What exactly changed?

The essence of the recent change is not that a new aircraft would depart from Budapest to Mongolia. There is still no scheduled direct flight between the Hungarian capital and Ulaanbaatar. The current development is that the MIAT code has appeared on the Turkish Airlines evening flight pair between Budapest and Istanbul. According to the published schedule information, flight TK1037 departing from Istanbul at 18:35 and arriving in Budapest at 19:35 also appears with MIAT code OM1033, while flight TK1038 departing from Budapest at 20:30 and arriving in Istanbul at 23:40 has also received code OM1034.

According to the official Budapest-Istanbul route information from Turkish Airlines, the company offers several direct flights daily between Istanbul and Budapest, and the flight time is approximately two hours. This provides a stable basis for transfer routes, as Istanbul is not only a gateway for visiting the Turkish city but also one of the most important Eurasian aviation hubs. Schedule and booking interfaces available on the MIAT side also show that Istanbul serves as a prominent connection point in the company's international network.

The codeshare is therefore primarily for those heading from Budapest to Ulaanbaatar or toward Mongolia, and who previously had to coordinate the Budapest-Istanbul and Istanbul-Ulaanbaatar segments separately. The new structure does not guarantee cheaper tickets, shorter wait times, or automatic baggage transfer in every case, but it increases the chance that the route can be better managed within a single airline partnership.

Why is this interesting for Hungarian travelers?

Mongolia is not a mass holiday destination in the Hungarian market, yet more and more travelers seek it who plan a unique nature-oriented experience, a tour, nomadic culture, desert landscapes, or a longer Asian circuit. Ulaanbaatar, the Gobi Desert, the Mongolian steppe, and the national parks are not typical weekend destinations, so a reliable schedule, realistic transfer times, and precise knowledge of baggage rules are particularly important when organizing the journey there.

From Hungary's perspective, Istanbul can be a natural transfer point toward Mongolia. There is a strong schedule connection between Budapest Ferenc Liszt International Airport and Istanbul Airport, and several eastward routes are available from Istanbul. If the onward journey appears on a single ticket or within a single airline partnership, it can reduce the risk arising from separate bookings: for example, that a passenger misses the next segment at their own expense due to a delay.

The change is also noteworthy from the perspective of inbound tourism. The codeshare may not only help Hungarian passengers toward Mongolia but also make it easier for Mongolian or Asian travelers to integrate Budapest into a European itinerary. Budapest has visibly strengthened in long-haul and transfer traffic in recent years, and any cooperation that presents the Hungarian capital in more distant markets can improve the country's tourism visibility.

What does codesharing mean at the passenger level?

The essence of codesharing is that one airline operates a flight, but other partner airlines can sell it with their own flight number. In practice, this means that passengers whose tickets show a Turkish Airlines flight number and those whose tickets show a MIAT flight number can sit on the same plane. The aircraft, the crew, the onboard services, and the operational decisions in this case are linked to the operating airline.

Therefore, passengers should check three things before booking. First: who actually operates the flight, as this determines check-in, some of the onboard services, and often the practical process of providing assistance. Second: whether the baggage goes through to the final destination or must be collected and checked in again in Istanbul. Third: what happens in case of delay or missed connection, especially if the passenger is traveling with several separate bookings rather than a single ticket.

According to the Turkish Airlines codeshare information, the operating airline must be indicated when purchasing the ticket and on travel documents. This is important because codesharing does not automatically unify every detail. Onboard services, loyalty program points, lounge use, special baggage, and modification rules may differ depending on which company issued the ticket and which operates the given segment.

How should the Budapest-Istanbul-Ulaanbaatar route be planned?

Those preparing for Mongolia should not only compare the price of the plane ticket. Much more important can be the length of the transfer time, the necessity of an overnight stay, the baggage rules, visa and entry requirements, as well as how much a potential delay disrupts the further program. Mongolia is a long-distance destination often involving off-road travel, where a lost day can easily affect the tour, the transfer organized with a driver, or domestic programs.

When departing from Budapest, it is worth comparing the schedule with BUD live airport flight information on the day of departure. If someone arrives at the airport from the countryside, a buffer time may be particularly important due to the late evening departure. Those going by car should account for parking in advance; those who do not want to depend on city transport can use the overview of Budapest airport transfer and taxi options. For early or late departures, hotels near Budapest airport can also be practical.

In Istanbul, one should not rely solely on the map during the transfer. IST airport is a massive hub where gate changes, security checks, the transit zone, and boarding time together can easily be longer than what we would expect at a smaller European airport. If the route includes an overnight or long wait, reviewing hotels around Istanbul airport or Istanbul airport transfers in advance can help in more comfortable planning.

Flexibility is particularly important toward Mongolia

Chinggis Khaan International Airport is the gateway to Ulaanbaatar, but Mongolian travel often does not end in the capital. Many visitors continue from here toward the Gobi Desert, Terelj National Park, Lake Khuvsgul, or rural yurt camps. For these programs, it is worth accounting for buffer days anyway due to the weather, the condition of the road network, and the great distances. On an international transfer route, this is even more important.

The best strategy for Hungarian travelers is not to look for the theoretically shortest transfer, but the most realistic route. If the ticket is within a single booking, it generally creates a more favorable situation in case of delay, but the airline conditions must still be read. If the journey consists of separate tickets, a buffer time of at least several hours is recommended in Istanbul, and it is worth considering travel insurance that covers costs arising from delays, missed connections, or baggage problems.

Another advantage of the codeshare may be that the MIAT name and flight number may appear in searches where the user specifically looks for routes departing from or heading toward Mongolia or Ulaanbaatar. This can increase Budapest's visibility for passengers arriving from the region. The effect is not measurable from one day to the next, but in tourism, many such small network developments together shape how easy it is to integrate a city into an international itinerary.

Not a breakthrough, but a useful network signal

The expansion of the MIAT and Turkish Airlines codeshare in Budapest is not news like the announcement of a new direct long-haul flight. It does not bring an immediate mass increase in traffic and does not fundamentally change the Hungarian aviation market. Yet it is an important signal: Budapest appears in more and more transfer routes connecting multiple airlines, which can improve the choice for more unique, distant destinations.

The most important message for passengers is simple: it is now worth re-examining the Budapest-Istanbul-Ulaanbaatar combinations toward Mongolia, but only with careful verification. Always check the operating airline behind the flight number, the final baggage destination, the transfer time, and the modification rules. If these are in order, the new MIAT code can provide a more convenient and transparent route for those planning a unique journey from Budapest toward Mongolia.
