I have not flown since 9-11, but could write a book about bad time at the airport. Only loosing 4 or 5 hrs on a flight is no big deal. I`ve done that acouple of times in 1 week. Several time I`ve lost a day. Sleeping in airports because you tried untill the last flight out to get out and haveing the first flight out the next morn leaving in 6 hrs. don`t give you much time to go to a motel so I would usually just sleep in the aitport. I have several 100,000 frequent flier mile I`ll never use.
