Standing at a gate for hours, or watching the baggage belt empty out, the first question is always the same: do I actually have a right here? You do. Denied boarding, cancellation and delay are governed by Turkey's SHY-Yolcu regulation, while lost or damaged baggage falls under the Montreal Convention.
These rights do not apply themselves, though. You have to ask for them, collect the right paperwork at the right moment, and respect strict deadlines. With baggage in particular, a few days' delay in filing can cost you the claim entirely.
This guide walks through the whole path in order: from the moment things go wrong at the airport, to a written claim with the airline, and then on to the aviation authority and the consumer arbitration board.
