Nearly all Tuesday morning flights from Will Rogers World Airport have been canceled in anticipation of an incoming snowstorm.
American, Continental, Delta and Southwest Airlines have canceled all departures through midmorning and tentatively scheduled first arrivals around 10:30 a.m.
Two flights on United Airlines, at 6 a.m. and 6:45 a.m., and a 7 a.m. departure on Frontier Airlines are still on the schedule but may be canceled, an airport spokeswoman said.
Airlines encourage customers to rebook their flight for later in the week or even next week to avoid the storm, which will impact much of the country as it moves east.
To change a ticket, call the airline. Airlines are waiving change fees. Don't go to the airport to change a ticket, she said.
