We were the same. Left over 1 hour late (on Norwegian Air) then a massive queue at Edin. passport control then another 30 min wait for the baggage. For an 11:55am flight we didn't get home until 4.30pm.
Air travel is just so rubbish these days. In retrospect I wish we'd gone for an afternoon flight, as well - end-of-day EasyJet flights are always mega-late these days, it seems, and we are all totally fried today. Zzzzz
