Travelers say the promise of refunds won’t do much if they’re missing out on important events.

This has affected almost every airline in some way. United, Delta and American Airlines have resumed some flights but say the disruptions could continue through the night. They have also issued travel waivers.

Airport officials are urging travelers not to come to the airport unless they know their flights are confirmed.
