Aer Lingus
Aer Lingus will be announcing Dublin-Bournemouth soon as I have just checked the ACL initial coordination report where it says Bournemouth will be a new route!
Ryanair will also Increase Dublin service too!
Don't take what you see in the ACL reports as gospel, especially at this stage. There's an awful lot of provisional and tactical slot booking that goes on between airlines or across multiple airports.
