To be unsure about talking to dp

[MyNameIsPenny]

Dp and I are flying for our holiday in a weeks time. The last holiday we had was 3 years ago.
Dp is an overweight man and on our last flight he found the plane seat a real squeeze and had to very uncomfortably wear the seat belt which was extremely tight.
He has gained weight since then and I'm worried he won't be able to do the seat belt up this time and will have to ask for an extension. He will be very embarrassed by having to do this but I am almost certain he will have to.
Part of me thinks he must have thought about this and just doesn't want to think more about it until he has to. But the other part of me is worried he hasn't actually thought ahead and will be genuinely shocked at not being able to do up the belt.
Should I bring it up or leave it?
I know bringing it up now won't change anything or make the belt fit so is it worth talking about?

"i had to have one, when I was pregnant, that was embarrassing enough."
