The Tumi 22021 fit the BA sizer. I tried it myself. I put it in wheels first and with a little work on the angle, it fit. It might be a little tight if stuffed, though there wasn't a lot of extra room in the bag. I only used the front pocket for toiletries.

It takes one suit, which it can do because of the extra width. I wore the jacket on the way over (and had it hung up in the closet) so that it would be unrumpled for for my 7:30 breakfast the next day. It looks to me like the shoulders/upper arms might need pressing (the whole suit might, and often does when flying with a normal suiter). But, the pants I took were fine.

I was flying from Terminal 3 and the BAA folks did not ask me if it would fit (they always did with my 22" TravelPro when I was flying BA, and it did not fit). So, a success.

mikel51, is the 14" limit for domestic airlines or foreign ones? I thought the domestic limit was just length + width + depth had to be less than or equal to 45". Are there other rules?
