Armed National Guard troops have been deployed to most major airports, and travelers can expect longer lines as airport officials have stepped up security measures -- including more thorough screening of passengers and luggage.
Students planning to fly should be aware of the new rules when packing bags, planning the time of their arrival at the airport and going through security checkpoints, airport officials said.
New luggage restrictions allow for only one carry-on item and one "personal" bag, such as a purse or a briefcase, said Mirinda Kossoff, communications director at Raleigh-Durham International Airport.
Sharp instruments of any kind, including nail clippers, Swiss Army knives, ski poles and knitting needles are prohibited in carry-on baggage, Kossoff said.
Curbside check-in has been reinstated at RDU after being suspended for several weeks, but all checked luggage could be subject to random searches.
Kossoff said passengers' pockets and other belongings will be examined. "If you're carrying a laptop, you'll have to take the laptop out of its case, and it will go through separately," she said.
Kossoff stressed students should arrive about two hours before departure time for domestic flights and three hours for international flights -- especially during the early morning and the late afternoon. "If at all possible, try to fly during the middle of the day," she said. "(And) bring a book."
Kossoff said finding parking spots at RDU should not be a problem, but passengers should remember that curbside parking at the terminals is not allowed.
She said unattended cars parked curbside will be towed, and people sitting in cars at the curbside will be asked to move.
