Heathrow Check-in/Bag drop
I'm flying out of Heathrow with Aer Lingus soon (LHR-DUB-ORD). Does anyone know:
- How early you can check in at the airport? I did previously hear of people who arrived too early being put in a 'holding area' although this might have been during the busy post pandemic time.
- Whether there is a separate bag drop line if you have already checked in and have a boarding pass?
