For example, if you want to submit a norwegian delayed flight claim, you should take into account the departure zone, the destination zone and the very company that provides services during your flight. If the conditions correspond the rules stated in the EC 261 regulation, norwegian delayed refund can be yours.
Sometimes even the EU airlines can refuse to give you the compensation. But it is not the reason to stop trying. Addressing the airlines with your claim is only the first step. And what about the next ones? There are two ways to go: you can try to address the airlines regarding your claim once again on your own or you can hire competent experts of the companies that deal with passengers’ claims. So, if the airline you’ve travelled with and want to get a refund from is the EU one, do not hesitate to submit your claim once again!
