I've no idea if LBA are giving Thomas Cook free landing & parking fees like they did with Monarch for first year of operation. Its a good incentive to do deals like that if it brings in money for the airport. LBA are not alone as other airports are known to do it.
Saw the new CEO David Laws appear on BBC Local News the other day saying they will be further announcements over next few weeks from Ryanair, Jet2 and TUi, regards replacing capacity lost after Monarch's sad collapse.
