Bull$#1t!!, the airline does not have to pay in this case! it is weather!
American Paxs, complaining ALL the time, bla bla bla bla... i want money...
The airline is trying to do all the best to take you to the destination despite the bad weather. The airline could have cancelled the flight (it would have been cheaper and easier) but they opted to give a try so this paxs can get to their destination. Bad luck, bad weather... not bad intention...
When the topic is weather, there is no reason to blame the airline..
