As of Sunday morning, 107 flights into and out of Logan had been canceled and more than 60 were delayed, according to the flight tracking service FlightAware. That marked a significant improvement over Saturday, when nearly 250 flights were canceled and more than 200 were delayed.

Massport, the state agency that operates Logan, expects operations to return to normal by Monday, spokesperson Jennifer Mehigan said Saturday. Federal Aviation Administration Administrator Bryan Bedford told reporters in Washington on Saturday that the U.S. air travel schedule should be back to normal by the end of Sunday.

The ground stop, the longest of its kind in the United States in 25 years, rippled across the global aviation system and left airlines working through backlogs of displaced passengers and aircraft. Travelers passing through Logan's terminals over the weekend faced crowded concourses and long lines as carriers rebooked passengers and repositioned planes.

For Boston-area residents, the disruption hit at the start of the busy holiday travel season, when flights are typically full and rebooking options are scarce. The recovery timeline offered by Massport and the FAA suggests the region's largest airport should be back to full operations in time for the coming week's travel.

Passengers with travel plans through Logan were advised to check with their airlines for the latest flight status before heading to the airport.
