When flights on this route do arrive late, the average delay is 2 hours 27 minutes, so choosing a carrier with strong on-time performance can make a difference on tight schedules.

  • To get a discount on long-term parking at the SEA airport, you can book a parking spot in the SEA on-site garage online. Floor 4 of the parking garage has the shortest walk to the terminal, so its parking rates are slightly higher than the other floors.

  • The spa, Be Relax, in terminals B and D of the Dallas/Fort Worth International Airport (DFW) are great places to relax and get the kinks out before you leave the airport and head into The Big D.
