Bag 21×14×9" vs sizer 21.6×15.7×9.4"
Yes — it fits the bin.
The verdict, explained
At 21x14x9", the LIGHT FLIGHT Expandable Suitcase fits inside Aer Lingus's 21.6x15.7x9.4" carry-on allowance with about 0.4" to spare on its tightest side. It should slide into the overhead bin without trouble at the gate sizer. 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.
