Frequently asked questions

Is it cheaper to buy a plane ticket from MacArthur Airport to Lambert-St. Louis Intl. Airport (STL) last minute?
Booking your trip from ISP to Lambert Field last minute could save you a pretty penny if you strike it lucky and find a terrific deal. However, fares don't typically get cheaper as the departure date nears. If you wait around, flights could also be sold out or the best seats gone (because no one wants the middle seat). If you'd rather not take any chances, book well ahead of your departure date. In fact, Expedia has some of the biggest deals up to 12 months in advance. If your preferred airline hasn't released tickets yet, check back regularly as deals are constantly updated on Expedia.

From Islip, you can travel to St. Louis via Lambert-St. Louis Intl. Airport (STL), Spirit of St. Louis Airport (SUS) and St. Louis Downtown Airport (CPS). It's wise to check which terminal is right for you before you make a decision. If you pick Lambert-St. Louis Intl. Airport (STL), it's about 19 kilometers northwest of the center of the city.
