Aer Lingus Car Seats Policy

Aer Lingus accepts car seats with a 5-point harness bearing an FAA or CE sticker, but only in forward-facing position. Rear-facing is prohibited. There is a 43 cm seat width limit, and car seats are only allowed on mainline flights, not regional services. If your route involves a regional connection, plan to gate-check instead.
