Flight deals from Las Vegas to Seattle

Flights on this page leave from Harry Reid International (LAS) in Las Vegas and land at Seattle-Tacoma International (SEA). Paine Field (PAE) in Everett is a different airport, so make sure your ticket shows SEA. Southwest, Delta, Frontier, United and American have appeared in EazAir's fare checks for this route. At LAS, American, Delta and Southwest use Terminal 1, while United and Frontier use Terminal 3, and SEA's train guide puts Delta and United at the S and A gates.

Getting to Harry Reid by bus means RTC Route 108 or the Red Line, and both stop only at Terminal 1, Level Zero. Anyone flying United or Frontier from Terminal 3 then rides the free shuttle between terminals, which LAS says takes about 10 minutes. LAS asks domestic passengers to arrive at least 2 hours before departure and to allow more time during major conventions. Repaving in the airport connector tunnels has cut lanes, and LAS expects the work to finish by the end of December 2026.

Sea-Tac is a single terminal split into six concourses, and the N and S concourses connect to the rest only by the SEA Underground train, which SEA says comes every three minutes. For Link light rail into downtown Seattle, go from baggage claim up to the fourth floor, cross the skybridge into the parking garage and follow the signs. SEA puts the downtown ride at 38 minutes. Lyft, UberX and taxis all collect passengers on the garage's 3rd floor.

Between 15 Sep and 8 Oct 2026, EazAir ran its first 8 fare checks for LAS to SEA, each asking for the lowest one-way economy fare for one adult departing 30 days later. The top result was at least double the bottom one, the 8 checks produced 7 different results, and the lowest came on 6 Oct. Neither United Basic Economy nor Frontier without a bundle includes a carry-on. Search your own dates, and check the final price, bags and fare rules on the partner site before you pay.

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.

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.
