Let's talk about flying your dog with Aer Lingus, because one detail trips people up fast: the cabin is off the table. Dogs travel by cargo only, and that changes your entire prep timeline. The science here is simpler than it sounds once you know the rules upfront. Too many owners discover this at the airport counter instead of at home. Read the checklist below carefully before you book anything at all.

Aer Lingus's pet policy splits into cabin and cargo. This page summarizes the weight limits, fees, brachycephalic-breed restrictions, and carrier specifications for both modes — sourced from the airline's official pet pages.

Cargo bookings for a dog must be made at least 48 hours before departure. Reserve the pet slot before finalizing any flight. Confirm the 48-hour reservation directly with the carrier, not through a third-party site. A dog without a confirmed cargo booking made inside that window will not fly. Lock the reservation early to hold the space.
The one-way cargo fee for a dog is 1000 EUR. Budget 1000 EUR per direction, and double it for a round trip carried both ways. Confirm the exact 1000 EUR charge at booking, since it applies per one-way segment. Set this figure aside before comparing ticket prices. Treat the cargo fee as separate from the passenger fare.
So here's the short version: cargo-only for dogs, a 48-hour booking window, and real fees to budget for. None of it is hard once it's mapped out. Pixel taught me that early prep beats airport panic every time.
