This is my first post here, though I've been lurking for a few weeks. We are signed up for the June 7-13 Best of Paris tour and I'm already obsessing over the details, including luggage. I've been following the other discussion about the Rick Steves 20-inch carry-on bag, which I'm considering, and have a related question.
I get that 20-inch bags are recommended for flights within Europe, but what about flights to and from Europe on major carriers? For example, if we fly on British Airways or Lufthansa or another European carrier from the U.S. to London, will there be the same stricter carry-on rules, or would a slightly larger 21-inch spinner bag that's just fine on domestic flights be OK for the international flights, too?
I like the looks of the RS 20-inch bag and may well end up buying it in any case, but just wondered if the size is that critical on the flights we'll be taking. Thanks to all for any input.
