American Airlines is, once again, expanding. With the addition of previously announced new routes, the carrier will launch 20 new seasonal routes for Summer 2020. Previously, the airline had announced 12 new routes for the summer travel season, and with additional 8 just revealed, flyers will have more choices than ever next summer when flying with American.

From Philadelphia, flyers will be able to hop on Saturday-only flights to visit Traverse City, Michigan; Nantucket and Martha's Vineyard in Massachusetts.

The airline also announced two new routes from Miami. The routes will be from Miami to Jackson, Mississippi and Des Moines, Iowa. American will offer two round-trip flights per weekend for these two routes.

Those looking to fly between Dallas/Fort Worth and Portland, Maine will be able to do so with American. This will be Saturday-only service.

American will also add a Saturday-only service linking Charlotte and Martha's Vineyard.

Finally, the airline will offer Saturday-only service from Ronald Reagan Washington National Airport to Traverse City, Michigan.

Martha's Vineyard is a popular summer beach destination. Traverse City is located on the shore of Lake Michigan and is a popular summer destination, too. While Miami is a destination in itself, those looking to fly to South Florida can also then easily make connections to plenty of destinations throughout Latin America and the Caribbean.

The new routes are part of the airline's broader summer expansion plans for next year. American will launch 20 new routes for next summer. A few months ago, American announced it would add new routes to Fairbanks, Kalispell and Bozeman.

Tickets for the new routes already went on sale Monday, November 25. The full schedule can be seen on American's website.
