Airlines add and drop frequencies throughout the year. Our agents can check what is actually scheduled on your dates.

A one-stop trip would most naturally connect through a hub such as American Airlines via Charlotte (CLT), which adds about 80 miles (13% beyond the direct distance) or United Airlines via Washington, D.C. (IAD), which adds about 170 miles (26% beyond the direct distance). Choose the connection with the best weather odds for your travel month and leave a comfortable layover; our layover guide explains how much time is realistic.
