Those are 100% wishlists. If BA put A320s in their own livery out of MAN the aviation universe would be "surprised". As a proof of concept, doing so at LGW has been painful as their cunning plan to pay low wages coupled with no nighstops
hasn't done anything for staff loyalty and retention. They exist at LGW partially to
ensure the London market can redeem avios, not even close
to that rationale at MAN.
It's a classic negotiating tactic in the industry to say "think again about xyz here in home base" or we shall move all growth elsewhere. See also Iberia Express. Aer Lingus need to focus on making sure DUB is a growing hub, and removing feed from LGW isn't helping THAT.
