Had a 9am flight with Dragon air to Fuzhou. We board the plane on time, sit down and then the captain comes on to tell us China air traffic control have suspended flights ( I'm told due to military exercises along the east coast) so the flight is delayed until 12:30pm. Question to Dragon Air - why the *&^# have us sitting on the tarmac for 3 1/2 hours when we could have stayed in the lounge !!! Aaaargggghhh !!!
