I DO know the LTN-GIB flights are not W patterns as I fly quite regularly on the service. What I was trying to explain is that there is a Manchester service which needs an A320 which does not fit in with either a Birmingham or a Luton schedule!
They are W patterns, but only on Mondays, Wednesdays and Fridays in the summer season. This winter there are A320's based at MAN so there is no W pattern. I am a regular traveler on the MAN-GIB service.
