Flights to Seattle

Seattle is a fully urbanized city that is surrounded by mountains, parkland and forests. With lake and waterfronts, it is also home to sweeping vistas of the Puget Sound. Book your flight to Seattle with Aer Lingus today and discover the outstanding natural beauty of this Pacific Coast gem.

Seattle Sightseeing

Get your bearings by travelling to the top of the Space Needle or by taking a ride on the Seattle Great Wheel. Walk through nine acres of sculptures at Seattle Art Museum’s Olympic Sculpture Park or stroll along the Ballard Locks and admire their surrounding gardens. Finish off the day with a local craft beer at the iconic Pike Place Market.

Hiking in Seattle

Seattle’s mountains make the city an ideal location for hikers of all ages and ability. Discovery Park covers over 500 acres and offers picturesque views and relatively flat terrain. If you are an experienced hiker or climber, try Mount Rainier, Tiger Mountain or Mount Si for higher elevations and taller challenges.

Seattle Museums

Discover the Seattle Art Museum, Frye Art Museum or Henry Art Gallery, all of which contain exhibits from modern and historic artists. Attend a show at the Pacific Northwest Ballet or enjoy a performance of the Seattle Symphony. Don’t miss the Seattle Pinball Museum which features dozens of free-to-play machines.

Seattle Transportation

Seattle is a walkable city with an extensive network of bike lanes and paths. Public transportation options include the Link light rail and King County Metro Transit bus service.

Upgrade your transatlantic flight to Seattle to Business Class and experience leg extra room and comfort as you arrive rested and ready to explore.
