Flying from Charlotte Douglas International
Charlotte Douglas International is American Airlines' second-largest hub and one of the world's busiest connecting airports, about 7 miles west of uptown Charlotte. American operates the overwhelming majority of flights across the US, Caribbean and Latin America, with nonstop service to London, Frankfurt and Munich on American, British Airways and Lufthansa.
