Frequently asked questions

Is it cheaper to buy a plane ticket from McCarran Intl. Airport (LAS) to ABE last minute?
Booking your flight from Harry Reid Airport (formerly McCarran Airport) to Lehigh Valley International Airport at the last minute could save you a pretty penny if you happen to find an epic deal.

If you’d rather play it safe, book well in advance of the date you want to leave. Note that some of the biggest deals can be found up to 12 months in advance. If your favorite carrier hasn’t released its fares yet, check back regularly as deals are updated on Expedia constantly.
