American Airlines warns flights may be more crowded in July

American Airlines said on Friday that it will no longer restrict the number of seats sold on flights beginning July 1, in an effort to come back from the impact of the coronavirus.

The announcement before a meeting between the chief executives of major US airlines, including American, and senior US officials, including Vice President Mike Pence, at the White House to discuss several virus-related travel issues.

US airlines are bleeding cash as travel suffers in the pandemic and have warned that capping the seats they sell on each flight to allow for more space between passengers is not something they can do forever.

American was previously limiting its seating capacity at 85% on each flight, or roughly 50% of the main cabin middle seats.

The company said it will notify customers if their flight is going to be full and allow them to move to more open flights when available, mirroring a policy by United Airlines.

Delta Air Lines and Southwest Airlines have said they will continue limiting their seating capacity through September.

The Allied Pilots Association, which represents American Airlines' pilots, has called for the government to subsidize empty seats to help people feel more comfortable about flying and create a level playing field.

Among measures to reassure passengers, American said it had teamed up with Vanderbilt University Medical Center to look into health and cleaning matters.

Starting June 30, it will begin asking customers during the check-in process to certify that they have been free of COVID-19 symptoms for the past 14 days.

US airline passenger numbers have rebounded from lows reached in April, but there is growing concern about the impact on travel of a fresh spike in coronavirus cases in a number of US states, including Texas, where American is based.
