Boston — The Boston airport where hijackers boarded the two planes that destroyed the World Trade Center reopened Saturday under tighter security, including close inspections and SWAT officers on patrol.
About 200 passengers a fraction of the usual 70,000 a day waited for morning flights at Logan International Airport.
With the reopening, Reagan National Airport at Washington remained the only major U.S. airport still closed to travel. Federal authorities said its proximity to the Pentagon and other federal buildings created enough security concern to keep it closed for now.
At Logan, many travelers did not seem to mind the added restrictions, the long waits or the presence of U.S. marshals, the Border Patrol and officers in black SWAT uniforms. A sign told passengers that once past security checkpoints, they could be subject to random searches and ID checks.
"They need to do what they need to do to make it safe," said Joe Carnation, 64, of Santa Rosa, Calif.
On Tuesday, hijackers boarding flights in Boston, Newark, N.J., and Washington crashed two airliners into the World Trade Center, one into the Pentagon, and a fourth into the Pennsylvania countryside.
Investigators are trying to determine if the 10 terrorists armed with knives were able to board two flights at Logan because security practices were not followed or were too lax.
Limited air travel resumed across the country Thursday and slowly increased on Friday and Saturday. The government also reopened the skies to most private planes, though they remained banned from flying within about 30 miles of Washington and New York City.
"At a time like this, who could complain about having to wait in line?" said Christina Bond, a resident of Walnut Creek, Calif., who was at the airport in San Jose, Calif.
In large part because many Americans are too scared to fly, Continental, Northwest and American said they are cutting back their schedules by 20 percent. Continental, the nation's fifth-largest airline, also said it is furloughing 12,000 employees more than one-fifth of its work force.
In Phoenix, America West announced it will no longer serve meals to save time and money.
Some terminals at New York's Kennedy Airport which along with the metropolitan area's two major airports reopened Friday looked like ghost towns, with restaurants shut down and only an occasional taxi passing outside. Others were mobbed with travelers, some of whom had spent days sleeping on cots and eating out of vending machines.
