For a dispute with an airline over a ticket, should I go to the commercial court or to the consumer arbitration committee / consumer court?

There used to be uncertainty on this in the Turkish legal community — notably, a 2019 regional appeal court decision held that under the Montreal Convention such cases belonged in the commercial courts. However, a 2022 Court of Cassation ruling (reversal in the interest of the law) established that for tickets bought for non-commercial, non-professional purposes, the consumer arbitration committee has jurisdiction, following the procedure set out in Law No. 6502 on Consumer Protection.
