Bear in mind that Brymon, Manx etc. were only bought to get the EGLL slots. The routine was:
- Buy the carrier
- Move the routes to EGKK
- Back fill the slots at EGLL with long haul
- Run down the carrier and dispose of it
This has largely come about because of the way in which slots at UK airports could not be bought 'over the counter', so the trashing of the regional carriers was the only alternative.
