We are flying home at the weekend, and I have priority + 2 bags, so I have the 10kg small case allowed in the overhead locker, and a small underseat bag.
But I've been shopping (did not think this through!). I want to add a 10kg bag to check in.
When I go into the app it looks as though I can pay for that, but it looks like I then lose my on board 10kg bag.
Am I being thick?' If I pay to check in a 10kg bag can I also take my small case on board?
