Logan International Airport will not have a runway open until at least 11 p.m. on Saturday, airport officials said. Authorities pulled crews off the airfield for five hours overnight due to whiteout conditions, causing the snow to pile up. “It’s very tough going and there’s still challenging conditions,” said Matthew Brelis, a spokesman for the Massachusetts Port Authority, which runs Logan.

Earlier, Massport officials expected to be ready for air traffic by 4 p.m. With most planes unable to get into Boston tonight, Sunday outbound travel will be limited. Normally, between 30 and 40 aircraft are parked at the airport overnight in order to be in place for the next morning’s flights out of Logan, Brelis said.

FlightStats.com shows flights from London coming in shortly before 4 p.m., followed by a trickle of other flights through the evening, but those planes will not be able to arrive as scheduled.

Amtrak has canceled all trains between New York and Boston Saturday, as crews continue to clear snow and downed trees from the tracks and make repairs. Service between Springfield and New Haven is also shut down; Downeaster service between Brunswick, Maine, and Boston has not been determined. Decisions about Sunday service will be made later in the day.

Greyhound, Peter Pan, BoltBus, and Megabus have all canceled Saturday service in and out of Boston; changes to Sunday service have not been announced.
