The verdict, explained

At 23.5x14.5x9", the Travelpro Platinum Elite 21" Expandable Carry-On Spinner exceeds Aer Lingus's 21.6x15.7x9.4" carry-on sizer — it is 1.9" too big on its longest side. Even with the straps pulled tight, the overage is too large to count on squeezing it in. Expect it to be turned away at the gate and gate-checked. On Aer Lingus: Short-haul Saver fare: small cabin bag only. It is too large for Aer Lingus's under-seat personal-item space, so it has to go overhead or be checked.

Manufacturer's note

Travelpro publishes two sizes for this bag: 23.5 x 14.5 x 9 in overall, counting the wheels and the top and side carry handles, and 21 x 14 x 9 in for the case itself. Our verdict uses the overall figure, which is over a 22 x 14 x 9 in sizer on paper. Travelpro says the bag is sizer-bin tested to fit the overhead bins of most major US airlines, because the soft carry handles fold flat; only the expanded bag may not meet airline limits. Keep it zipped unexpanded at the gate.
