Some tips to make an easier trip

From packing to getting through security checkpoints, here are tips for travelers who will face new restrictions and longer waits at airports:

PACKING: No liquids or gels of any kind are allowed in carry-on baggage until further notice. This includes all beverages, cologne, hair gel, suntan lotion, contact lens formula, toothpaste, shampoo, and all items of ``similar consistency." The only exceptions are baby formula and juice -- but just for those passengers traveling with children-- and medicines, which must have the traveler's name on the container.

Many airlines are now allowing passengers to check one or two more bags than usual without penalty. Pack light and put a card or slip of paper with your name and contact information inside bags.

For flights from the United Kingdom to the United States, no electronic devices, including cellphones and music players, can be carried onto the plane, but can be in checked luggage. US officials are not yet banning such devices.

GETTING TO THE AIRPORT: Plan to allow two hours or more to get through security lines. Logan is urging passengers departing on international flights to allow three hours.

WAITING IN LINE: Be alert for airport security personnel calling for passengers who are on flights approaching departure time to go to the front of the line.

STAY IN TOUCH: Use airline services that let you sign up to have text messages sent to your cellphone with updates on whether your flight has been delayed or canceled.

SWITCHING FLIGHTS: Several major US airlines are allowing passengers who have flights in the next several days to switch to later dates without penalty In many cases airlines are rebooking those passengers who missed a flight because of security delays for free.
