Taking my 3 DS on a long overdue trip to Scotland to see family. Flying Gatwick to Glasgow which I've done many times before. I know passport isn't strictly necessary but when I've flown alone this is what I've always taken as seems easier. None of the kids ages 6,4 and 2 have passports. 6 year old has an expired baby one. They all have the same surname as me. Should I take their birth certificates?? Do I need anything?? Just wondering how it works?? Anyone done this before? I'm not actually taking them out of UK so does it matter?? I've looked on easyJet website and FAQ and can't find anything! Thanks!
