When searching for a good deal, it’s best to be prepared for potential fluctuations in price. We recommend booking at least 47 days in advance, which can save you up to 110% on flights from New Haven to St. Louis compared to booking the week you need them.

For sooner than that we have options available in the next 3 days from $542.
Due to multiple factors, expect to potentially pay more when booking in December. For low rates, September can be a great choice for travel to St. Louis. Flights to St. Louis from New Haven in September are about $334 on average during September, but can be found for as low as $119.

I was emailed and told that if I check my luggage early I get a 10 dollar discount, also on the website, if it's under 50 lbs. it would be $40.00 I was charged $65.00 on first flight and $60.00 on second flight (second flight I checked in early, did not receive the discount, both flights my luggage was under 40 lbs.). Avelo destroyed my luggage, wheels were tore off, and plastic was ripped off.
