Aer Lingus offers online check-in to streamline airport procedures. Online check-in typically opens 24 hours before departure and closes 1 hour before domestic flights and 2 hours before international flights.
Steps for online check-in:
- Visit www.aerlingus.com and navigate to the check-in section
- Enter your booking reference and surname
- Select your seat and confirm your baggage allowance
- Receive your boarding pass via email and save it to your device or print it
- Proceed to bag drop at the airport if you have checked baggage
Practical tip: Complete online check-in well in advance to avoid last-minute queues, especially during peak travel periods.
What if I miss the online check-in window?
You can check in at the airport desk, though this may result in longer queues. Airport check-in counters open 2–3 hours before international flights.
Can I check in at the airport if I only have a carry-on bag?
Yes. Passengers with only cabin baggage may proceed directly to the gate after presenting their boarding pass, though early arrival is still recommended.
