Frequently asked questions

Is it cheaper to buy a plane ticket from STL to DUT last minute?
Booking your journey from Lambert-St. Louis Intl. Airport (STL) to Unalaska Airport (DUT) last minute could save you a nice sum if you're lucky enough to find a good deal. However, airfares generally don't get cheaper as the departure date nears. If you choose to wait, flights could also be booked out or the best seats taken (we hope you like the middle seat!). If you'd rather not hedge your bets, book well ahead of the date you want to leave. It's worth noting that some of the best deals can be found up to 12 months in advance. If your favorite airline hasn't released tickets yet, check back regularly as deals are updated on Expedia all the time.

You have two options when jetting from St. Louis to Unalaska — Unalaska Airport (DUT) and Akutan Airport (KQA). If you arrive at Unalaska Airport (DUT) you'll be about 3 kilometers northwest of central Unalaska. Check in to your hotel, then set out and experience the local sights! Dutch Harbor Naval Operating Base and Fort Mears and Sitka Spruce Park are two of this destination's favorite attractions.
Can I change the date of my flight from STL to Unalaska Airport (DUT)?
Easily make changes to your Lambert-St. Louis Intl. Airport (STL) to Unalaska Airport (DUT) ticket by logging in to the Expedia Trips portal. But before you make any adjustments, read through the rules in your itinerary to find out what you're allowed to do and if fees apply for changes.
