I read this article on the front page reporting that only 4 in 10 people claim the airline compensation from long flight delays that they are entitled to. In my own experience, it can be fairly painful to get anything: Delta denied any compensation for an overnight delay due to engine failure because the people in charge of hotel vouchers had already left... I remember asking a friend to send a stern letter to their legal department in the following weeks that got me a voucher for a few hundred bucks (probably still not sufficient for what ended up as a 24hr delay on the heels of a weather related 24hr delay).

But aside from that, I suspect many people also don't know when they are entitled to compensation. This may be especially confusing because credit cards offer different protection as well.

Is there a nice summary of coverages and compensations available for common problems and delays?

For example: My first leg of a connecting ticket (US-EU) is delayed by a half hour, and Norwegian told me they will rebook me to a later flight (4.5hr longer layover). If I wanted to risk the original connection, they said they would not honor the remainder of the ticket as I'm now aware already that I'd have less than a 1hr layover. Plus, no meal voucher (or anything else).

The above article prompted me to wonder whether there should be compensation for it. But I couldn't find anything, and I'm probably looking up the wrong terms, too. I'm glad I get to fly out on the same day at least...
