Whenever I have flon BA I have found the temperatures to be extremely cold. The cold air blowing around my feet was most uncomfortable. I do find problems like this are more prevalent with airlines such as Thomas Cook.
I would like to ay Easyjet domestically have been the nicest ride for me. A good temperature in the cabin and a more than abiding crew when asking them to adjust temps.One or two on the flight however did mention they worked for BA in a previous life when they enquired if I was going further afield than just STD.
