Frequently asked questions

Is it cheaper to buy a plane ticket from MacArthur Airport to St. Marys Airport (KSM) last minute?
Booking your trip from MacArthur Airport to KSM at the last minute could save you cash if you strike it lucky and find a real bargain. However, airfares usually don't drop in price as the departure date nears. If you take a wait-and-see approach, flights could also be sold out or the best seats gone (that could mean the middle seat!). If you'd rather err on the side of caution, 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 favorite carrier hasn't released tickets yet, check back regularly as deals are constantly updated on Expedia.
What airports do you fly into for St. Mary's from Islip?
There are three airports you can fly into when going from Islip to St. Mary's: St. Marys Airport (KSM), Pilot Station Airport (PQS) and Mountain Village Airport (MOU). St. Marys Airport (KSM) is about 3 kilometers southwest of the middle of St. Mary's. Before selecting where you'll touch down, keep in mind flight times, the distance to your next stop and the convenience and cost of getting from the airport.
Can I change the date of my flight from MacArthur Airport to St. Marys Airport?
Easily make changes to your MacArthur Airport (ISP) to St. Marys Airport (KSM) trip via the Expedia Trips portal. Before you make any amendments, read the rules in your itinerary to find out what the carrier will allow you to do and whether fees apply. Some airlines have a change fee per person, on top of any difference in ticket prices. But if you booked in the last 24 hours, you may be able to cancel for free and arrange new flights.
