Direct vs. Connecting Flights for HPN to STL in August

Connecting flights often mean longer total travel time but can save money and reduce the need to drive into heavier New York-area airports. Driving to LaGuardia (LGA) or Newark (EWR) for a nonstop flight may reduce travel time and risk of missed connections, but factor in traffic, parking costs, and convenience.

CTA: Compare airlines and filter by total travel time when searching HPN to STL flights for August to pick the best balance of price and convenience.
