Aer Lingus has boosted its transatlantic network with the return of its service to San Francisco.
The carrier said the service will be more easily accessible because of connections from UK cities including Manchester, Edinburgh and London.
It also plans to add further UK connections from Bristol and Leeds to San Francisco via Dublin from 15 April.
Aer Lingus said it would operate a four times weekly service to the US West Coast city from this week rising to a daily service from 26 March.
Bill Byrne, executive vice president, US, for Aer Lingus, said: “With the convenience of US customs and immigration pre-clearance at Dublin, time spent connecting through Dublin provides customers with a speedier journey overall, as they arrive in the US as a domestic passenger.”
Aer Lingus is also resuming daily flights to Los Angeles from 12 May and flights to Seattle five times a week from 26 May.
