Aer Lingus Cabin Bag Size 2026: Free on Every Fare

Aer Lingus is one of the few airlines flying from the UK where the overhead cabin bag is included on the cheapest fare rather than sold as an extra.

Aer Lingus' cabin bag allowance

• Cabin bag: 55 x 40 x 24 cm, up to 10kg, in the overhead locker.
• Personal item: 25 x 33 x 20 cm, under the seat in front.
• Included on every fare, Saver included. You get both bags without paying an upgrade.

What fits?

That 24 cm of depth is more generous than most. Ryanair, TUI and Vueling all stop at 20 cm, so a bag that is too fat for those will usually clear Aer Lingus comfortably.

Our Vacuum-Compression Pack is 49 x 32 x 15 cm as standard and 49 x 32 x 20 cm expanded, so it fits with room on every side even in suitcase mode.

Regional flights changed in March

Aer Lingus Regional used to cap cabin bags at 7kg, which caught out anyone connecting from a smaller airport with a bag packed for the mainline limit. From 3 March 2026 regional matches mainline: the same 10kg and the same 55 x 40 x 24 cm.

They do weigh it

Gate agents check both size and weight, and bags over either limit get tagged for the hold. The 10kg is the one to watch, because the generous dimensions make it easy to pack past it without noticing. Compression helps you use the space, but it does not make anything lighter.
