There's certainly scope, and BIA management a) are not happy about it, and b) cannot prevent another GHA coming in ( more than 2m pax p.a.), but no-one else can come in without having a contract from an airline. EZY signed for 2 years with Servisair last October, the next biggest is whatever Flybe operate from BRS, and Flybe have a global contract with Servisair. No-one is going to come in for 4 a day from Eastern.
So it's Servisair
