Aer Lingus is to fly direct from Dublin to Seattle from May 2018. The airline will fly to Seattle-Tacoma International Airport four times weekly on Monday, Wednesday, Friday and Sunday. The route launches on Friday 18 May 2018.

Flights will be operated using an Airbus A330 aircraft in a two class, economy and business, configuration.

This is the latest addition to a growing portfolio of transatlantic routes for Aer Lingus from Dublin. It has recently launched Miami and announced Philadelphia. It has also launched Los Angeles, Hartford, Newark and Washington Dulles in recent years.

The route will be codeshared with BA and it will be possible, via to book a one-stop flight from London to Seattle via Dublin with the benefit of US customs & immigration pre-clearance and a direct flight back from Seattle to London. BA flies to Seattle up to two times daily on most days of the week.

It’s also worth noting that BA does have a codeshare partnership with Alaska Airlines at Seattle to destinations such as Anchorage and Portland. Aer Lingus may well follow BA and add Alaska Airlines as a codeshare partner.

If you book via direct from Dublin it will also be possible to buy an “unbundled” saver fare which does not include a checked bag, seat selection nor blankets and headphomes.

Aer Lingus is due to join the transatlantic joint-business with American Airlines, BA, Finnair and Iberia which is pending regulatory approval. However, based on comments by its CEO this week, there are no immediate plans for Aer Lingus to join the Oneworld alliance.
