The verdict, explained

At 21.5x14x9", the TIYFIY Zipperless Hardshell Carry-On fits inside SWISS's 21.6x15.7x9.0" carry-on allowance, right at the limit. It should slide into the overhead bin without trouble at the gate sizer. On SWISS: Economy Light still includes a cabin bag (8kg). It is too large for SWISS'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.
