Frequently asked questions

Is it cheaper to buy a plane ticket from Lambert Field to ISP last minute?

It's worth noting that some of the best deals can be found up to 12 months in advance. If your preferred airline hasn't released its fares yet, check back regularly as offers are updated on Expedia constantly.
