Last March our flight out of West Palm Beach did not leave until 4pm. Instead of going to the beach, etc. we just decided to go to the airport early. By arriving early we were first on the list to give up our seats (due to over booking.) As luck would have it they asked us to give up our seats for $300.00 vouchers. They booked us on the next flight and we arrived at our final destination only 45 minutes later than our original flight. And we used the $600.00 in vouchers for our next cruise. So sometimes it pays to get to the airport earlier.
