Extension-Belt-Aeroplane,OMG

Are you sure you need one?

When I went from Vancouver to North Africa and back I was about 290 or so, and didn't need one on any of the flights (only 2 flights to get there, but 3 or 4 coming back, can't remember for sure). All of the seat belts fit me, even with a bit of room for adjustment.

Even when I was about 380 I flew from Vic to Winnipeg, the flight attendant was very rude and tried to shove an extension at me (not being discrete at all), but I just managed to get the thing done up without the extension (it was a tight fit, but it was buckled!).

I'd say go there with a positive mind and see how you do. If you sit down and it doesn't fit just tell the people you're traveling with "I'm just going to go ask the flight attendant a question" and ask them very discretely if they have an extension.

Don't assume you'll need an extension, it's going to depend on where you carry your weight and the airline/airplane itself.

If you're asking about how to ask? If you're certain it's going to be necessary you can ask an attendant as you pass them when you board the plane, they'll just need to know your seat. Or you can wait until you're in the seat, and then catch an attendent as they go by during boarding and pre-takeoff.

It's never been an issue for me, nor an embarrassment. Just a fact of life, though it is nice that I've now flown once not needing one, and a couple of times borderline.
