the oneworld page already seems to be updated to show access for BA passengers is to the Aer Lingus Lounge in T2, with this additional complication
- Access for customers travelling on British Airways and Iberia flights with scheduled departure time after 9:00am only. Customers departing on the following British Airways flights are invited to use the Dublin Airport Authority Lounge in Terminal 2: BA831, BA923, BA4461 and BA4463.
BA is no longer listed to use the lounge in T1 now.
