They’re not abandoning GLA, who said that? They’re closing the crew base and operating inbound sectors on DUB-GLA. STN-GLA is dropped again but they use this to pile pressure and punish airports who don’t give them the terms they want. They will no doubt operate a few inbound flights for next summer and I suspect LDY will return.
If they were actually giving up on GLA, DUB-PIK would be back and GLA dropped. This is a ploy, and fair play, is business.
Growth will slow, of course it will, it’s a mature market now and the volume of untapped new opportunities is a lot smaller.
