Saturday brought one of the busiest travel days of the holiday season, as millions of people head home for Christmas or for other gatherings. An estimated 122.4 million people are expected to be on the roads, the highways, the railways and the runways. As of Saturday morning, flight operations w ere running smoothly for the most part at LaGuardia, Kennedy and Newark Airports, particularly after the Tri-State area dealt with rough weather earlier in the week. Travelers who spoke with NBC New York maintained good spirits, even as some dealt with delays. One young student told News 4 that he had been waiting for a flight that had been delayed twice since 10pm Friday night. Flyers at LaGuardia walked into long lines at places like Terminal B. Some had to wait up to 20 minutes to check in and drop their luggage. Travelers like Valerie Pinkney Williams told News 4’s Jessica Cunnington that being prepared for the wait was key. “God forbid the alarm doesn’t go off. God forbid someone is cranky, like all of us are early in the morning, without our coffee, without our cereal, whatever,” she said. “So as long as the clothes are laid out, everything is ready, packed, ready to go. We go, ‘bing, bam, boom.’ This line means nothing.” Some eight million people are expected to take domestic flights across the country, and many of them are doing so this weekend. As always, airlines encourge passengers to arrive early at the airport. For those traveling by car, AAA says 109 million Americans are expected on the roads. That’s a 2% increase over last year and would set a travel record. AAA says gas prices are lower than a year ago, with the national average hovering at about $3.00 a gallon. ...read more read less
