(CNN) -- Here are some of the latest travel-related developments stemming from Hurricane Irene:
Major airlines -- including US Airways, American, United, Continental, Delta, JetBlue, Southwest and AirTran -- dropped ticket-change fees for passengers scheduled to fly to or from many cities along the East Coast this weekend and early next week.
The Port Authority of New York and New Jersey announced Friday night that five airports it operates -- John F. Kennedy, LaGuardia, Newark Liberty, Teterboro and Stewart -- would be closed as of noon Saturday to all arriving international and domestic flights.
"The five airports will remain open for departing flights pending further updates," the agency said, adding that the decision to halt arrivals is being done "to avoid stranding passengers at its airports when the region's mass transit systems suspend service."
By Friday night, United and Continental airlines had canceled 2,300 flights for Saturday and Sunday, the carriers said in a joint statement.
The two airlines -- which merged last year -- will halt their operations Saturday at Newark Liberty, Kennedy and LaGuardia airports, and will likewise suspend regional service via United Express, Continental Express and Continental Connection to and from these locales.
United and Continental will suspend operations on Saturday at the Raleigh-Durham, North Carolina; Richmond, Virginia; and Norfolk, Virginia, airports. The airlines will take a similar step Sunday in Albany, New York; Boston; Hartford, Connecticut; Manchester, New Hampshire; Portland, Maine; Providence, Rhode Island; and White Plains, New York.
Delta Air Lines plans to cancel about 1,300 Delta and Delta Connection flights between Saturday and Monday, according to spokesman Anthony Black.
On its Twitter feed, Delta said that all flights to and from LaGuardia, John F. Kennedy, Newark and Philadelphia airports on Sunday have been canceled.
American Airlines canceled all Washington-area flights from noon Saturday through noon Sunday, according to spokesman Ed Martelle. The airline also canceled 32 Friday flights.
JetBlue has canceled almost 900 flights in the Northeast ahead of the storm. Most of those are Sunday and Monday flights out of the New York metro area and Boston, spokesman Mateo Lleras said.
Air Tran has canceled 265 flights from Saturday to Monday, according to spokeswoman Judy Graham-Weaver. That includes flights into and out of the following locales: Allentown/Bethlehem, Pennsylvania; Atlantic City, New Jersey; Baltimore-Washington International in Maryland; Boston; New York's LaGuardia airport; Newport News, Virginia; Philadelphia; Portland, Maine; Richmond, Virginia; Washington's Reagan airport; Washington Dulles airport in northern Virginia; and White Plains, New York.
Southwest announced on its website that it would not have flights to and from several airports on the East Coast. That includes no Southwest service Saturday and Sunday from Newark, LaGuardia, Long Island-Islip and Philadelphia airports. The airline won't fly to or from the Baltimore/Washington airport; Norfolk, Virginia; or Washington-Dulles in northern Virginia on Saturday. Similarly, there will be no Southwest flights Sunday to Boston; Hartford; Manchester, New Hampshire; and Providence, Rhode Island.
US Airways is planning significant cancellations in the Washington metro area starting at 6 p.m. Saturday, carrying into Sunday. Philadelphia, New York and New England routes will see significant schedule reductions Sunday, according to an airline spokesman.
Baltimore/Washington International is "monitoring terminal and airfield drainage, checking generators and securing any equipment that may become airborne as a result of high winds," said Paul J. Wiedefeld, the airport's executive director.
Albany International Airport in New York is safeguarding the terminal, airfield and aircraft. "Our goal is to ensure the safety of travelers, staff and equipment and be prepared to resume full operations by Monday morning," said John A. O'Donnell, CEO of the Albany County Airport Authority.

BUSES, TRAINS AND ROADS
Following up on widespread cancellations announced earlier, Amtrak said Friday evening that none of its trains would be operating Sunday and there would be even fewer routes in service Saturday because of the storm.
