Frequently asked questions

Is it cheaper to buy a plane ticket from Indianapolis Airport to Lambert Field last minute?
Booking your flight from Indianapolis Airport to Lambert Field last minute could save you a tidy sum if you strike it lucky and find a real steal. However, fares usually don't come down in price as the departure date nears. If you wait, flights could also be booked out or the best seats gone (hello, middle seat!). If you don't want to risk it, 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 airline hasn't released its airfares yet, check back regularly as offers are constantly updated on Expedia.
