Flight deals from Newark to Seattle

This page starts in New Jersey, at Newark Liberty International (EWR), and finishes at Seattle-Tacoma International (SEA); JFK and LaGuardia (LGA) are other airports. Four airlines, American, United, Sun Country and Delta, turn up in EazAir's fare checks for the trip. At Newark, the airline list puts American and Delta in Terminal A and Sun Country in Terminal B, while United can use A, B or C, by flight. Sea-Tac's 2 Sep 2025 train guide gives Delta and United the S and A gates.

Rail riders face two sets of works. Until 13 Nov 2026, AirTrain at the Airport Train Station gives way to free shuttle buses between 5 a.m. and 3 p.m. on most weekdays, and the airport asks you to add 10 to 15 minutes. NJ Transit's Portal Cutover timetable also thins out weekday trains into Penn Station New York, and NJ Transit says its regular schedule resumes 15 Nov 2026, subject to safety testing. AirTrain skips Terminal A: from that station, a covered walkway takes 15 minutes and the shuttle ride 5 minutes.

For the Link light rail at Sea-Tac, SEA's directions take you from baggage claim up to the fourth floor and over the skybridge into the parking garage, with signs to SeaTac/Airport station. If you would rather not walk, a free Train-to-Plane shuttle covers that link from 5 a.m. to midnight. App rides split by type: Lyft and UberX on the 3rd floor of the garage, Uber Black and premium rides at a baggage claim door you choose.

Running from 16 Sep to 12 Oct 2026, EazAir's first 10 fare checks on EWR to SEA each sought the lowest one-way economy price for one adult travelling 30 days later. They came back with 5 different results, the highest under one and a half times the lowest, which arrived on 24 Sep. On Sun Country's base fare, a personal item is included but a carry-on is not. Search your own dates, and check the final price, bags and fare rules on the partner site before you pay.

Arriving at Seattle-Tacoma International (SEA)

Airline	SEA gates
Delta	S and A gates
United	S and A gates
Other airlines	Check your boarding pass or airline app.

From SEA's SEA Underground guide dated 2 Sep 2025, which says Delta, United and almost all international airlines use the S and A gates. Gates can change, so check your boarding pass.

SEA has one terminal with six concourses: A, B and S at the south end, and C, D and N at the north end.
The N and S concourses are not connected to the other gates, so you reach them on the SEA Underground train. SEA says a train arrives every three minutes.
The Blue Line links the S, B and A concourses, the Green Line links N, C and D, and the Yellow Line shuttles between the A and D stations only.
SEA says every security checkpoint gives access to all gates.

Travel tips

Arrive early for domestic flights

TSA generally recommends arriving at least 2 hours before a domestic departure, more at larger hub airports during peak travel periods.

Pack a mixed carry-on

Keep a change of clothes, chargers, and any essentials in your carry-on rather than only your checked bag, in case of a delay or a bag that doesn't arrive with you.

Ease jet lag on longer routes

On longer cross-country flights, adjusting your sleep schedule a day or two before departure and staying hydrated in flight can reduce jet lag on arrival.

Screenshot your confirmation

Save a screenshot or PDF of your booking confirmation and boarding pass before you travel, in case you lose signal or battery at the airport.

Check in online when it opens

Most airlines open online check-in 24 hours before departure. Checking in early can help with seat selection and, on some airlines, boarding group assignment.
