Not even. If air crew is unavailable because a previous flight ran long due to headwinds and they are out of allowable flying hours for the day, week, or month? That's "weather-related" and you get nothing.
I agree, I could have been clearer by repeating the exclusion for weather delays on one or more line items. I'm sure there are even borderline cases where a denial by the airline might be questionable and your only course of action would be to repeatedly and/or strongly state your case, escalate the matter up the chain-of-command, call/file your case with the government (e.g., DOT ACPD), file a request for arbitration (i.e., if your ticket requires), file a small claims suit, etc.
Yes, exactly.
"Airline-caused" means things like:
- flight crew delays/unavailable
- mechanical issues
- overbooking
