If your flight is delayed, it is important to obtain a certificate from the airport confirming the delay or cancellation of the flight and stating the reason for the delay or cancellation. In addition, please provide us with copies of your flight tickets (used, unused and new), proof of expenses and confirmation from the airline of the refund or non-refund. Your claim can be registered easily in the e-office of BTA, where you can upload the necessary documents. If you do not have the opportunity to register a claim with BTA e-office, send a completed application and the abovementioned documents to kahjud@bta.ee. If you register a claim in the e-office, filling out an application is not necessary.
