Mass transportation to and from the Boston area was virtually shut down Friday as police conducted a massive manhunt for one of two suspects in Monday's Boston Marathon bombing. The exception was air travel, as planes took off and landed at Logan International Airport.
Authorities in Boston suspended all mass transit indefinitely, telling commuters via Twitter: "Go/stay home."
Amtrak stopped trains north and south of Boston. All major intercity bus lines suspended service to the area. Passengers were being allowed to get refunds or rebook for travel at a later date. And the airlines were allowing customers to change plans without paying a fee.
Amtrak service about an hour south of the city in Providence, R.I was suspended, as was part of its Downeaster service, which runs from Brunswick, Maine to Boston, according to spokesman Cliff Cole.
Authorities suspended service on commuter trains into Boston as well as the city's subway -- called the T -- and the city's buses. That includes the Silver and Blue lines between Logan and downtown.
All major highways remained open, according to the Massachusetts Department of Transportation. The exception was in Watertown, Mass., the center of the manhunt.
Megabus canceled at least 22 buses between Boston and New York, New Haven, Conn., Hartford, Conn., Burlington, Vt. and Philadelphia. More than 1,000 passengers were affected, according to spokesman Mike Alvich. They received emails offering a refund or the option to rebook for free.
Bolt Bus, Greyhound and Peter Pan Bus Lines also suspended service. Passengers booked on canceled Bolt trips received refunds to their credit cards, according to Timothy Stokes, spokesman for Greyhound and Bolt Bus.
Across much of the Boston area, streets that would normally be bustling were quiet.
In Somerville, a densely populated city of about 75,000, authorities requested that residents stay inside with doors locked and not go to work.
People largely heeded officials' pleas, said Bob Trane, an elected alderman in Somerville, which abuts Cambridge, about 5 miles northeast of Watertown.
"I'm just like everybody else in Greater Boston, just staying at home, glued to the television," Trane said. "There is nobody out in the streets, very few cars, very few people walking."
Logan airport remained open, although getting there was a challenge for many passengers. On a typical day, the airport has about 1,000 flights. Fewer than 10 flights had been canceled by 10 a.m., mostly because of weather delays in New York, according to flight tracking site FlightAware.
The airport has been operating at a heightened level of security since Monday's attack, according to Matthew Brelis, director of media relations for MassPort, the public agency that runs Logan.
The Massachusetts State Police set up a roadblock Friday morning and were searching some of the vehicles entering the airport.
While no mass transit was reaching Logan, private cars, taxis and the Logan Express -- a bus service to suburban park-and-ride facilities -- were still able to enter the airport.
The biggest hassle for travelers were taxi lines, which Brelis described as "exceedingly long" during the late morning. Officials were asking people to share cabs to nearby location. By noon the backlog had cleared.
JetBlue, the largest airline in Boston with about 120 daily flights, was allowing anybody scheduled to fly to or from Boston to change their ticket for free. Passengers could also opt to fly to Hartford, Providence or any of the New York area airports JetBlue serves.
Delta Air Lines -- which has about 70 daily Boston departures -- also hadn't canceled any flights. Spokesman Morgan Durrant said the airline expected on-time departures and was considering extending a travel waiver issued earlier in the week.
US Airways was running its 70 daily flights with minimal delays. The airline is letting passengers change tickets to any other flight through Monday.
American Airlines hadn't canceled any of its 31 daily flights in Boston. The airline was allowing passengers scheduled to fly today to rebook onto flights Saturday or Sunday without penalty, according to spokeswoman Andrea Huguely.
United Airlines has about 100 daily flights in Boston and allowed anybody flying Friday to rebook for anytime within a year of the day their ticket was purchased.
Southwest Airlines allowed passengers flying Friday to change their tickets to flights within the next two weeks. It's AirTran subsidiary is allowing changes to flights through Monday.
The Federal Aviation Administration imposed an air traffic restriction on the Boston area "to provide a safe environment for law enforcement activities." It barred flights below 3,000 feet in a radius of 3.5 miles around the manhunt area. The restrictions had minimal impact on commercial flights in the area.
