We're flying with Jet2 from LBA (Leeds Bradford) in a few days. Our 'manage booking' says we can check-in online but from past experiences, we have seen no difference between 'that' and not checking in online.
Our seats are already chosen, we have to queue anyways to check in our hold luggage and from what I can remember from last year, jet2 do not have a designated desk for dropping off hold luggage (hold luggage need individual tags on anyways!)
So is online check-in worth it when you have 3 hold pieces of hold luggage and a buggy to check-in?
