True, but we can't rely on that database: BIO still doesn't show BA access, but it is now allowed, and there's no entry for FLR when there is access there. Moreover Air Berlin does have an access agreement with Sala Bellini in Catania, and I've taken advantage of that.

However I think your earlier comments are correct. It's not really a new route, but very few of the low intensity leisure destinations have lounge arrangements, even when there are lounges in place, and there are a few airports now where AB have better lounge access than BA (ACE and KRK as well as CTA - and more alarmingly CUN!).
