Airlines had begun waiving fees for the latest tropical system that threatened to snarl flights on the U.S. mainland.
American, JetBlue, Southwest and United were among the big carriers to invoke flexible rebooking policies as of Friday morning for Tropical Storm Nate, which threatened to make landfall along the U.S. Gulf Coast this weekend as a possible hurricane.
The storm was centered in the western Caribbean early Friday. It was projected to move past Cancun and into the Gulf of Mexico on Saturday, according to the National Hurricane Center. By late Saturday or early Sunday, projections suggested Nate would come onshore somewhere between Louisiana and west Florida.
