The verdict, explained

At 21.7x14.8x10", the Amazon Basics 21-Inch Hardside Carry-On exceeds LOT Polish Airlines's 21.6x15.7x9.0" carry-on sizer — it is 0.1" too big on its longest side, 1.0" too big on its shortest side. Expect it to be turned away at the gate and gate-checked. On LOT Polish Airlines: Economy cabin bag weight limit is 8kg. It is too large for LOT Polish Airlines's under-seat personal-item space, so it has to go overhead or be checked.
