One person runs this site. Corrections are the most useful thing you can send.
Please say so. Every airline figure here links to the carrier page it came from, so if a limit has changed, sending the link and what it now says is enough for us to fix it the same day. This is the kind of message we most want to receive — the whole point of the site is being right.
Send the manufacturer’s spec page. We need dimensions the maker publishes as the external size, including wheels and handles — a retail listing that quotes the packing case is what causes most of the wrong advice on the internet, and we would rather leave a bag out than list it with a number we cannot stand behind.

Same address. We are happy for the data to be cited — a link back is appreciated.

Manufacturers publish dimensions inconsistently, and a “20-inch” spinner is almost never 20 inches once you count the wheels. Where a brand states dimensions including wheels and handles, that’s the number we use. Where it only publishes the case, we say so on the card. Airlines measure the outside of your bag — wheels, handles, straps and all. Anything marked borderline is down to the gate agent, and remember that a soft bag squashes into a sizer while a hard shell won’t.
