When I travel to Boston I get the following data from our travel office on an e-mail: AA79 21st August Dep: 13:45 Arr: 15:30. Fine. But in order to get there I could use a bit more information. The plane leaves from Terminal 4 at Heathrow and there is a business-class lounge which I can use. By talking with some colleagues who travel to Boston regularly I know that it is possible to request an upgrade to first class, that I can use a last track through customs and that the plane generally arrives ahead of schedule.
