Smaller musical instruments can be taken on board as part of your free carry-on baggage allowance. They must be small enough to fit in the overhead locker, or under the seat in front of you.
They must also fit within the following dimensions:
Aer Lingus flights
55cm H (21.5") x 40cm W (15.5") x 24cm L (9.5")
Aer Lingus Regional flights
48cm H (18.5") x 33cm W (13") x 20cm L (8")
Musical instruments that are larger than the permitted carry-on baggage size, e.g. a guitar, and if you wish to carry the item in the cabin, you can purchase an additional (window) seat for the instrument online and normal charges and taxes will apply.
However please be aware that there is no baggage allowance associated with the additional seat purchased for the instrument.
The instrument should be booked in the family name of the passenger and the first or given name being 'ONE' and that of the instrument e.g. 'SMITH/ONE CELLO MS' or 'SMITH/ONE SAXOPHONE MR'.
The weight of the instrument, including its carry case, must not exceed 75kg/165lbs
It must also fit within the following dimensions:
94cm H (37") x 58cm W (23") x 41cm L (16")
Instruments that do not fit within these dimensions or weight limit must be checked in as baggage.
If you're travelling with Aer Lingus Regional: please check in at the airport of departure instead of checking in online. This is so the check in agent can determine the exact weight of the instrument, including its carry case, and to ensure that the seat next to you is blocked and reserved only for the instrument.
Larger musical equipment (including but not limited to instruments such as double bass, harps and drums) is unsuitable for carriage in the cabin and must be checked in.
For flights operating to/from North America, musical equipment is carried as part of the standard baggage allowance. For all other flights a fee applies. This fee will be charged at the same rate as sports equipment. Normal excess baggage rates will also apply if applicable.
