Future not all FRs
A smaller Baby may mange quite will under new owners in long run. BHX will not wish Ryanair to be so big that they can get blackmailed. I am sure that a good rate could be agreed to keep baby viable. Its new owners also have quite a few planes that could get passed down to the new bady in the family.
Ryanair is likley to be paying less per pax at BHX and is killing the profits of other airlines at the airport. They may part company again.
