The verdict, explained

At 21.7x14.8x10", the Amazon Basics Expandable Hardside Carry-On exceeds TAP Air Portugal's 21.6x15.7x7.9" carry-on sizer — it is 0.1" too big on its longest side, 2.1" too big on its shortest side. Expect it to be turned away at the gate and gate-checked. On TAP Air Portugal: Discount fare excludes the cabin trolley. It is too large for TAP Air Portugal's under-seat personal-item space, so it has to go overhead or be checked.

Airlines measure at the widest external point — wheels, handles, and bulging pockets all count. Pull soft-bag compression straps fully tight before you size it.
