Glasgow hasn't been confirmed as going yet. It already operates with only 4 a day on airbus (rest are embraer)
hopefully with new flights like Basel and Tripoli Glasgow will build back up with connecting passengers. Swiss passengers from Scotland will now have to go through LHR on bmi rather than LCY.
If they could just re-align economy domestic services with BA and offer passengers the same in economy and keep the enhanced flexible economy service they could get a lot of business back from BA.
