Frequently asked questions

Is it cheaper to buy a plane ticket from Sea-Tac Airport to UNI last minute?
Booking your flight from Sea-Tac Airport to UNI last minute could save you cash if you hit the jackpot and find a terrific deal. However, fares generally don't get cheaper as the date of departure nears. If you take a wait-and-see approach, flights could also be sold out or the best seats gone (because no one wants the middle seat). If you'd rather not hedge your bets, book well ahead of your departure date. Note that some of the biggest deals can be found up to a year in advance. If your preferred carrier hasn't released its fares yet, check back regularly as offers are updated on Expedia constantly.
What airports do you fly into for Union Island from Seattle?
Union Island (UNI), Argyle Intl. Airport (SVD) and Canouan Island (CIW) are your options when traveling from Seattle to Union Island. Roughly 2 kilometers east of downtown Union Island, Union Island (UNI) is the city's main entry point. Consider things like flight departure and arrival times and the distance to your hotel before settling on an airport. Chatham Bay Beach and Belmont Bay are a couple of great attractions to add to your must-see list when you reach your destination.
