Actually I would think regular FT'ers would know not to ask for compensation for a 90 minute delay; 1-2 hour delays (though not much more than that) are part of flying, regardless who is at fault. But, INfrequent travelers may see a 90 minute delay as absurd and complain to anyone who will listen. OP has <20 posts and joined this year; doesn't mean he/she isn't a frequent traveler, but that was the first thing I thought of when I read the complaint.
