My experience is usually amazing but I made great mistake of booking Terminal 5 lounge as I booked with British Airways. American Airlines was operating my flight so obviously it was from Terminal 3 . When I arrived at the Terminal I explained to the staff at assistance what I had done . I was taken to a waiting area and asked about the Aspire lounge and was told there wasn't one !!!!!!!!! As I was collected to go to the departure area what did I pass but an Aspire lounge. To say I wasn't very happy is an understatement as I'd had to buy food and a drink !!!!!!!!!
