Third year running we have been to Orlando and flown into Sanford Airport. Booked with Travel City Direct and flew on Air Atlanta 747. This must be the oldest aircraft I have ever flown on, every screw on every panel had been redrilled to hold the panels in place. I never checked, but I'm sure the plane was that old it even had a rear gunner!We were sat next to the centre toilets, which both filled up to overflowing on both the flights out and back. The outbound flight was delayed by 2 hours, the return flight by 2 hours plus we had to make an unscheduled stop in Bangor to refuel, which entailed another two hour wait on the runway. Onboard staff were not interested and once the meals had been served they disappeared completely.
