Travel Tips
Arrive early and adhere to minimum time requirements, especially at major airports and for long-haul flights. Missing check-in or boarding deadlines results in denied travel with no refund.
For early morning flights (departing 05:30–08:00 from Dublin or Cork), Aer Lingus offers evening-before check-in and bag drop from 16:00–19:45.
Use online check-in and mobile boarding passes where possible for faster processing. Mobile boarding passes are accepted at major airports, notably Dublin and London Heathrow.
