BAR training is up to standard. Exactly the same as BA standard in fact. The difference is that BA Connect crews were never in BAR, BAR was subsumed into BACX then BA Connect. People seem to think that because they fly around in a plane with BA colours on it then they are BA. Well, like the advert says, it doesn't work like that. You could work in a Macdonalds, wear the uniform, flip the same burgers, but it doesn't mean you work for Macdonalds, you work for whichever franchise happens to be running that particular branch. Its the same with BACon staff. They don't work for BA, they work for BACon, and when they leave BACon to go to BA they join a new company at the bottom of the seniority list.
PS BACon staff shouldn't be flying 767s out of LHR and it would be an understatement to say BASSA are fairly livid about it!
PPS BA make everybody return their uniform when they leave any BA-uniformed employment thats why you hand the uniform back when you leave BACon. The priority is to make sure uniforms remain acounted for, not to save a pittance on issuing new uniforms.
