Very amused by the BBCs latest air travel chaos piece this morning as they transferred to the jet2 check in area at EMA. The check in hall was deserted at 0815, as all 6 jet2 aircraft had departed on time by 0800 (as had all 6 FR). All the correspondent said was I promise you it was busy. Great advert for travelling with jet2 from EMA!
It's just the nature of these regional airports, similar aircraft utilisation on similar sector lengths, but it does feel Jet2 especially seem to do this bunching of flights on purpose. In NCL the other day all 8 Jet2 aircraft were scheduled out within one hour during the afternoon. Considering they have their own check-in and ground handling resource, you'd feel it would make better use of those to spread the schedule a bit.
I get the logic at the destination end, so multiple flights can use the same resort transfers, but not so much in the UK. Guessing Jet2 have crunched the data and do what works for them, but it seems an inefficiency to me.
