Compensation for flight delay rules are different for international flights vs domestic, and even for flights originating in different countries. If your flight falls under EU rules you generally are entitled to more than you'd get elsewhere.

I was recently involved in a cancellation of a flight from Mexico to the US. We were delayed almost 24 hours and received no vouchers and no miles, but did get put up in a great hotel with fine dining and even a glass of wine at dinner.

I'd say that your poor treatment was worth more than what you received, assuming that your delay was MX rather than WX related (since the weather was apparently OK at HND, I assume it was a MX issue).

I don't even know the current DL compensation rules for MX delays on domestic flights, but just a couple of years ago a similar delay on a domestic flight would have gotten you $400 in vouchers, plus hotel and meals.


BTW: Prepare yourself--eventually someone will say "They got you home, didn't they? That's compensation enough!"
