My dad was on a flight to St. Louis today (Tue Sept 18th 11am). He got to the airport 2 hours before the flight time as suggested, and said the airport was empty, like a ghost town.
You'll have to call the airline to make sure your flight is still scheduled.
Traffic controllers and airlines we're complaining that the skys we're too crowded. Well, now their wish came true, noone is flying.
What irks me is that I heard a report about some news reporters that went on a flight 2 days after the tradegy, and the pilots had the cockpit door open. Man, close the cockpit door, lock it, and don't come out.
