On an LAX-LHR flight today then couple next two me had twin girls of 18months. At no point did the crew offer them seat belt extensions for them. I always see this on BA/VS. Is it not a legal requirement for everybody to be strapped in?

Worse still the parents let the kids wonder around when the seat belt lights where on and the most amazing thing I saw was that they let them walk about as soon as we touched down, as we where taxing fast.

Does anybody know if UA are supposed to provide belts?
