Frequently asked questions

Is it cheaper to buy a plane ticket from Sioux Gateway Airport (SUX) to Sea-Tac Airport last minute?
Booking your flight from Colonel Bud Day Field to Sea-Tac Airport at the last minute could save you dollars if you're lucky enough to find a good deal. However, fares typically don't come down in price as the date of departure nears. If you hold off, flights could also be booked out or the best seats taken (don't get stuck in the middle!). If you'd rather play it safe, book well ahead of your departure date. In fact, Expedia has some of the biggest deals up to a year in advance. If your preferred carrier hasn't released its airfares yet, check back regularly as deals are updated on Expedia constantly.
What airports do you fly into for Seattle from Sioux City?
With Seattle - Tacoma Intl. Airport (SEA), Renton Municipal Airport (RNT) and Boeing Field Airport (BFI) to choose from, flying from Sioux City to Seattle is no sweat. The city's main terminal, Seattle - Tacoma Intl. Airport (SEA), is about 19 kilometers south of the center. Besides ticket prices, consider things like the ease of getting from the airport and the distance to your hotel when deciding where to land. Get your Seattle adventure off on the right foot by checking out Space Needle and Pike Place Market.
Can I change the date of my flight from SUX to Sea-Tac Airport?
Plans don't always work out, so Expedia is here to help make amending your trip as easy as possible. First, find your SUX to SEA itinerary through the Expedia Trips portal and look up the fare rules and restrictions about change fees or other charges.
