Must say am gonna miss seeing the GB/BA A320's down at Gib. In general they have been most reliable and while on board has certainly been curtailed over the years I suspect the 737'400's will not be so reliable?
That said - life goes on and EasyJet have posted some wonderful fares from the rock back to Blighty and return....and as long as BA keep the service great - for onward connections.
