Please, enlighten us, where will you spend your money next time? Did everyone make it to PIT safely? If so, then three hours on the 'tarmac' shouldn't be that bad. You are in a pilot's forum, so I won't go through the time or effort of explaining the reasons why they may sit for three hours, you should be able to figure it out. The reality is it could happen to any airline at any major hub. You're not going to find sympathy from many people hear.
