The U.S. Department of Transportation has proposed minimum service requirements for airlines based on schedules before the coronavirus outbreak.

Airlines are supposed to refund flyers’ money if they cancel a flight. United has introduced more restrictive policies during the coronavirus crisis.

Airlines are extending fee waivers and some are offering passengers more flexibility to use travel credits as the coronavirus crisis drags on.

With the latest round of flight cuts, Southwest will have cut nearly 40 percent of its daily flights, including all international flights.

The coronavirus travel fallout is deepening so rapidly airlines are increasing their flight cuts and making plans to park planes.

Airline travel bookings have plunged rapidly, trip cancellations have surged and the drop-off is accelerating due to coronavirus concerns.

Southwest Airlines said it has had several days of more cancellations than bookings and that planes are flying half empty in recent days.

The airline’s CEO, Oscar Munoz, and president, Scott Kirby, said late Sunday that the airline carried 1 million fewer passengers in March versus a year ago.

White House officials have repeatedly said restrictions on travel within the United States are under consideration. When will they come?

A logjam awaited Americans following new European travel restrictions, which require returning citizens to be screened for coronavirus at 13 airports.
