BD unlike BA has 2 cabin planes throughout UK, although the seating is still 6 across (but more legroom). Its NOT worth an upgrade or higher fare, unless part of a complete int'l C or F fare. On their flights you often get a meal in Y, if you are a RCC member you can use their lounge, and their flights are rarely more than an hour. One note, however, they can be VERY RESTRICTIVE on carry on size.
