No, it is too big on American Delsey Helium Aero Carry-On: 21 x 14 x 10 in with wheels (21 x 14 x 10 in) vs limit 22 x 14 x 9 in
Longest side (height)+1 in
Middle side (width)+0 in
Shortest side (depth)-1 in

How was this checked?

The bag's three sides come from its own listing, which states the size includes wheels and handles. Both sets of numbers are sorted largest first and compared side by side in inches, the unit American publishes. Exactly on the limit counts as a fit; a tenth over does not. The total size, including handles and wheels, must fit the sizer at the airport.

Price when checked: $149.99, listed weight 8.52 lb. This bag is expandable; the verdict is for the zipped, unexpanded size.
