I had been travelling back and forth to Atlanta all 4 weeks in June and had delays or cancellations for each leg of the flight.

The worst was June17:I arrived in PHL on a Sunday morning for an 11:00 am US Air flight. Ten minutes before departure, all passengers on this flight were told that it was cancelled and that there were NO flights to Atlanta until Tuesday night. Many people were trying to get to Atlanta for a Pharma conference. I had never seen anything like that before. ( I managed to find a flight from Wilmington, DE to Atlanta on a Delta flight that day, on my own)

Each of my flights leaving Atlanta in June was cancelled or delayed by as much as 6 hours. The Deltat attendants were very apologetic and offered free drinks and snacks. It's not their fault

All of my co-workers on this project experienced the same thing , on all airlines: Continental, Delta, US Air, Northwest.

Not fun travelling this summer at all
