Expansion warning: zipped open, this bag runs 12.5 in deep (27.8 x 17.8 x 12.5 in) and clears 0 of 19 airlines instead of 0. No airline verdict changes, but a packed-out bulge can still catch in the sizer.

American Tourister's official US product pages (shop.americantourister.com) publish two spec-table fields in inches: External Dimensions, which the page's own tooltip defines as the total case size including handles and wheels, and Internal Dimensions, defined as packing space without handles or wheels, always listed in Height x Length x Width order with Height as the largest number. Many current PDPs on the site name sizes only by category (Carry-On, Medium, Large, Underseater) rather than printing a nominal inch number. Some retailer listings for this brand separately publish Body Dimensions (shell only, matching the nominal inch name) alongside Overall Dimensions (with wheels), and the gap between the two can be several inches, for example a nominal 28 inch Wavebreaker body is 28.0 in tall but its overall exterior with wheels is 31.0 in tall.
