Hotel Mode you say ...."Would have thought the thread made it obvious, but yes they fly 737's from Gatwick, Newcastle and Dublin as per cityflyer in previous years. And Manchester on the RJ100, which incidently has GPS based EGPWS so doesnt suffer from this unfortunate problem!"
So NOT a BA aircraft or trained crew then....!
These days just because an aircraft has BA colours it does not mean it is a BA aircraft. In 5 years it will, when the new scope agreement comes in.
