How far is Boulder from Custer? Here's the quick answer if you have a private jet and you can fly in the fastest possible straight line.

This is a relatively short flight in a private plane, but you might be planning to book a commercial flight. In that case, your travel time would really need to include how many minutes to get to your local airport, wait for security, board and taxi on the runway, land at the other airport, and get to your destination.
