While football fans couldn't have been luckier with the unseasonably tolerable weather during the Super Bowl, luck ran out by Monday morning as snow and ice returned to the Northeast, disrupting travel in the air and on the roads and rails.
"This morning is off to a rough start for the Northeast," FlightAware CEO Daniel Baker said in an email to CNBC. He said Philadelphia and Newark-Liberty were the hardest hit airports, as were the regional airlines that operate for United, US Airways and American.
By 10:30 a.m. EST, more than 1,300 flights were canceled and more than 3,200 delayed.
Those on the private jets were not spared the pain.
"If you left during or right after the game, things went smoothly," Jeff Trance, senior vice president of Air Partner, said in an email to CNBC. "The poor quality of the Super Bowl resulted in early departures, and relatively good weather helped alleviate big delays out of Teterboro (N.J.) after the game. However, those who scheduled a morning departure to avoid the post-game rush are ironically feeling the pain of departure delays and steep de-icing costs due to the snow."
The February mess comes on the heels of a very bad January, when weather disruptions cost passengers more than $2.5 billion and airlines between $75 million and $150 million, according to masFlight, a cloud-based data and software company specializing in airline operations.
