Aer Lingus's 21.5 x 15.5 x 9.5 in works out to about 3166 cubic inches (51.9 litres) of cabin allowance, which ranks 7 of 22 among the airlines we have verified, about 7% more than the median carrier.
No other airline in our set publishes exactly 21.5 x 15.5 x 9.5 in, so a bag bought specifically for Aer Lingus is not automatically safe elsewhere — check before you fly a different carrier.
6 of the airlines we track allow a larger bag and 15 allow less, so a bag sized to Aer Lingus clears roughly 73% of the carriers here.
