Passengers traveling on the Ashgabat–Istanbul route can take advantage of a special Business Class upgrade offer throughout July. From 3 to 31 July 2026, all passengers on this route are eligible for a 30% discount on upgrades from Economy Class to Business Class.

Business Class upgrades can be purchased within 0–72 hours before departure through the airline's official website or mobile app, at the Turkish Airlines sales office (cash payments accepted), or at the airport check-in counter when paying by credit card. The offer is subject to Business Class seat availability during the final 72 hours before departure.

As part of the promotion, the one-way upgrade price has been reduced from USD 449 to USD 314.30.

Passengers should note that after upgrading to Business Class, the conditions of their original Economy Class ticket remain unchanged. This means that the baggage allowance and fare rules of the original ticket continue to apply, despite the enhanced onboard Business Class service.
