Personally, in a situation like this, I feel the people shouldn't be the ones suing; rather, it should be the government. The FAA has already fined SWA, but a judgement "for the people" could be used to make sure this doesn't happen again ... at SWA or anywheres else.
These people don't deserve any money. Since they weren't damaged, the worst I could see is that they get a free ticket since the first one was considered breached.
What scares me is, a jury is going to hammer SWA if this actually gets to court. And it will set a precident (spelling?) for future cases against all airlines.
