- complain to national authorities
If you don't receive a reply from the airline within 2 months or if you are not satisfied with the reply, you can lodge a complaint with the relevant national authority
in the country where the incident took place, within a reasonable timeframe. The national authority should provide you with a non-binding legal opinion on how to proceed with your claim.
