Small instruments (within 55 x 40 x 24 cm or 48 x 33 x 20 cm for regional flights) count as carry-on. Medium-sized instruments (e.g., guitars) require an extra window seat purchase. Large instruments (e.g., cellos) must be checked, with fees similar to sports equipment.

Pets:

Short-haul flights: €40; long-haul flights: €160. Service dogs travel free in the cabin, subject to conditions.

Urns with ashes can be carried in the cabin if in a cushioned, leakproof, non-metal container.
Medical devices (e.g., CPAP, nebulizers) are allowed in the cabin if they meet FAA requirements. Defibrillators cannot be used onboard.

AerClub/Status Benefits: Silver, Platinum, and Concierge AerClub members get a 10 kg carry-on allowance included.
Strict Enforcement: Aer Lingus is known to be strict, especially at Dublin Airport. Self-service kiosks and staff may check weights, with fees for non-compliance. Some leniency (e.g., 11 kg) has been reported, but it’s not guaranteed.
Codeshare Flights: If booked through partners (e.g., British Airways), the operating carrier’s policy applies, but BA bookings often include a 23 kg checked bag.
