All Aer Lingus flights between Dublin and London Heathrow now depart from and arrive into Terminal 2.
Customers travelling from Dublin to London Heathrow are asked to present at Terminal 2.
Aer Lingus is currently operating a range of European services into and out of Terminal 2 over the next few weeks, as they progress the full transfer of operations into the new terminal.
During this period, Aer Lingus is asking all departing passengers for destinations other than London Heathrow to present at Terminal 1 as normal unless advised otherwise by the airline.
This programme of proving flights will enable the airline to ensure a smooth transition of its operations from Terminal 1 to Terminal 2.
