Flight deals from Dallas to Seattle

Dallas Fort Worth International (DFW) is the departure airport for this search, and flights land at Seattle-Tacoma International (SEA), known as Sea-Tac. Love Field (DAL) is a separate Dallas airport, and Southwest is not on DFW's airline list. Delta, American and United have appeared in EazAir's fare checks for this route. DFW lists Delta and United at Terminal E, while American uses gates in all five terminals. SEA's train guide lists Delta and United at the S and A gates.

From downtown Dallas, the DART Orange Line runs to DFW Airport Terminal A Station near Gate A10, and TEXRail from downtown Fort Worth stops at Terminal B. Each terminal has its own checkpoint and TSA PreCheck, and DFW says Skylink, its free train inside security, is the shortest way between terminals. Delta and United travellers in Terminal E will find CLEAR at checkpoint E18. American flyers leaving from Terminal C should note that the C30 check-in area and checkpoint are closed for construction.

Sea-Tac has one terminal with six concourses. If your Delta or United flight parks at an S gate, the SEA Underground Blue Line links that concourse with the B and A concourses, since S is not connected to the other gates on foot. For Link light rail's 1 Line, go up from baggage claim to the fourth floor, cross the skybridge into the parking garage and follow signs to SeaTac/Airport station; SEA puts the downtown ride at 38 minutes. Lyft, UberX and taxis all pick up on the 3rd floor of the garage.

EazAir ran its first 6 fare checks for DFW to SEA from 13 Sep to 5 Oct 2026, each one asking for the lowest one-way economy fare for one adult, departing 30 days later. Those 6 checks returned 5 different results, the highest at least one and a half times the lowest, and the lowest result came on 26 Sep. Search your own dates, and check the final price, bags and fare rules on the partner site before you pay.

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.
