Wow, did not know what I thought was a simple question could spark such debate!
I actually fly *A more often than Delta, and will be travelling *A to Europe. I hadn't even considered the size being an issue when I ordered it. On the plus side, I am active duty military, so I'm entitled to 2 bags when I travel, so worst case scenario, I'll have to check it.
However, I am now rethinking whether I want the hassle of this bag or whether I just want to go with the non-widebody.
