The chairman of the House Transportation and Infrastructure Committee on Thursday urged US airlines to maintain at least one seat between all passengers and cap seating at 67% of capacity on narrow-body airplanes to address the coronavirus pandemic. In a letter to a group representing major airlines including Delta Air Lines, American Airlines, Southwest Airlines and United Airlines, Representative Peter DeFazio said airlines should 'leave at least one seat-width of spacing between passengers and to dynamically adjust fares as needed to account for the effect on load factors.'
