Frequently asked questions

Is it cheaper to buy a plane ticket from HLN to Lambert Field last minute?
Booking your flight from Helena Regional Airport (HLN) to STL last minute could save you a tidy sum if you're lucky to find an epic deal. However, fares typically don't come down in price as the departure date nears. If you procrastinate, flights could also be booked out or the best seats gone (because no one wants the middle seat). If you want to be on the safe side, book well in advance of the date you want to leave. Note that some of the biggest deals can be found up to a year in advance. If your favorite carrier hasn't released its airfares yet, check back regularly as offers are updated on Expedia constantly.

From Helena, you can journey to St. Louis via Lambert-St. Louis Intl. Airport (STL), Spirit of St. Louis Airport (SUS) and St. Louis Downtown Airport (CPS). Check which terminal is more convenient for you before making your decision. If you decide to land at Lambert-St. Louis Intl. Airport (STL), it's roughly 19 kilometers northwest of the city center.
