Was forced to check my bag, didn’t want to but really upset when got on the plane and nearly all the overheads were empty. And then even more upset when they lost my bag! So far it’s been 5 hours and they have no clue where my bag went. Don’t force me to check a normal carry on when there’s more than enough room!
