From March 27 through April 30, food and drink service will be reduced based on flight length and destination. According to the carrier, “full service will resume once the COVID-19 situation has stabilized.”

For the time being, for flights shorter than 2,200 miles, alcohol will not be served in the main cabin, but available upon request in first class. Non-alcoholic beverages (water, canned drinks or juice) will be available on request, but no snacks or other food for purchase will be served. Meals will also not be offered in first class.

For flights over 2,200 miles, alcohol will only be served in the Main Cabin and Main Cabin Extra during long-haul, international flights. Alcohol will be available in first class. In the Main Cabin, other drinks will be served as usual, but no snacks or other food for purchase will be served. Meals will be served in the Main Cabin on long haul, international flights, while meals in first and business class will be served on one tray instead of the traditional “courses.”

Effective March 26, American will also temporarily close most of its Admirals Club lounges until further notice. Lounge services -- like food and drink options, restrooms and showers -- will also be suspended. The carrier will, however, keep operating front desk customer service at large air hubs in the U.S. as well as London's Heathrow Airport.

To further encourage safe social distancing during the outbreak in accordance with Centers for Disease Control and Prevention (CDC) guidelines, American will block out 50 percent of middle seats and all seats adjacent to flight attendant jump seats on every flight.

Starting March 24, gate agents are also allowed to reassign seats to establish more room between passengers during flights. After boarding, customers can also move to a new seat if they desire more space in their ticketed cabin as long as it does not disrupt aircraft weight or balance restrictions.
