082808delta.jpgPassengers who boarded a Delta flight to Las Vegas at JFK airport at 10:30 a.m. yesterday had plenty of time to catch up on their Sudoku, because they ended up being stuck on the plane for over 7 hours. The flight never left JFK due to scattered thunderstorms on Sunday. Passengers were placated with water and “warm Sprite,” according to one account, and were finally permitted off the plane sometime after 5:30 p.m. A Delta spokesman could not explain why passengers were not allowed to return to the gate, and promised to refund their money. Which is a nice gesture, since airline passengers still have no rights.
