With the economy being what it is, travelers are choosing more affordable conveyances where they can. The waits are longer than usual for Amtrak.
"We have a lot of people riding Amtrak today. About 70 percent more than a normal Wednesday. So we're changing the boarding patterns a bit, queuing people up in the Great Hall and then bringing them down," said Marc Magliari, Amtrak spokesperson.
Conditions were similar at the downtown Chicago bus terminal.
"I didn't know so many people took buses... because planes are so expensive right now. But, no, I didn't anticipate that it would be so long of a wait," said Allison Clayton, bus traveler.
No matter the transportation mode, planning for delays is the name of the game. Especially during a period where, according to AAA, 38 million Americans will be on the move.
"Some go last weekend. Some travel earlier in the week, some travel today and tomorrow, but where it all focuses in is really is on Sunday when everybody comes back. That's really our emphasis day," said Don Dillman, vice president of United Airlines operations control center.
Whether it's Sunday or Monday, according to the Chicago Department of Aviation, travelers know the back half of their journey is likely to be tougher.
The Scott family members are meeting their grandparents in Mexico.
"They're flying to Peru, and then they came to Mexico, and they're going to meet us there," said young Andrew Scott.
"With all the different flights going out, there are certain times of the day when the checkpoints are at their busiest, so we always recommend people getting to the airport early," said Annie Greg, TSA.
Some families were proud of their airfare deals.
"We paid $400 for this flight, and it's near Thanksgiving and a direct flight, so I think I got a good deal," said John Rivers.
"His family is in Puerto Rico, so we're visiting the whole family for three days, then coming back for our family for Thanksgiving," said Ryann Rivers.
Others were still just happy to be able to afford a holiday tradition.
"Fortunately, we haven't been impacted by the downturn in the economy, so we're lucky," said Thomas McDonal.
As for road travel, AAA says 1.8 million people in Illinois will be hitting the roads. Road travel is up by 4 percent in Illinois, particularly because of the economy. People are opting to drive five or six hours in some cases instead of getting that one-hour flight.
Road travel is up 2 percent natinowide, with air travel down 6 percent.
Americans search for cheaper Thanksgiving trips
The Miles family is changing it up this year in the annual American race to make it to the table for Thanksgiving dinner. Instead of booking plane tickets, they opted to take the 1,100-mile trip by train.
Airline tickets seemed too pricey, so they paid $800 for the five of them to travel roundtrip by train from their Syracuse, N.Y., home to Omaha, Neb. to see family. Airfare would have totaled more than $2,500, the family said.
"Economic considerations topped the list for us," Maureen Miles, 44, a doctor's office receptionist, said while sitting with her husband and three kids at a crowded Union Station in Chicago before their train departed Tuesday afternoon.
"If the price was right, we would have considered flying," she said.
With economic pressures still hitting household budgets hard, many Americans are forgoing air travel for the Thanksgiving holiday and opting for cheaper alternatives. Others are staying home completely -- partly to avoid traffic and airport lines, partly to save a buck.
Thanksgiving travel plummeted a staggering 25 percent between 2007 and 2008, and many of those habits seem to be sticking this year. The number of people traveling is likely to stay about the same, inching up only by about 1.4 percent, according to an AAA prediction based on a survey of 1,300 households.
About 38 million domestic travelers are expected to go somewhere this holiday -- a far cry from the roughly 58 million who made holiday journeys in 2005 when the economy was better.
Traveling for Thanksgiving at any cost was too much for Julie Bennink, 26, who works in public relations in Chicago. Unexpected medical and other bills meant she couldn't afford paying what would have been at least $400 for a rental car and gas to drive the three hours to Grand Rapids, Mich., for Thanksgiving dinner with her family.
"My mom was not really thrilled with me when I told her," Bennink said.
Her plan B for Thanksgiving was to take a 15-minute city bus ride to a friend's house and bring a cornbread casserole.
Most people have calculated that travel by car often makes the most financial sense, said Alan Pisarski, a leading transportation analyst. About 33 million people are expected to travel by car this Thanksgiving, according to AAA.
That was how travelers who stopped at a service plaza along Interstate 75 in southwest Ohio saw it.
Because of the economy, John and Janet Lawson of Elizabethtown, Ky., opted to drive 350 miles to Dearborn Heights, Mich., to make dinner for one of her sisters rather than spend the holiday with her other siblings in Minnesota.
"It affected us as far as the distance we would travel," Janet Lawson said. "We didn't want to do any flying."
The Lawsons left home at 4 a.m. Wednesday, hoping to beat traffic. Their SUV was loaded with turkey, gravy, stuffing, cranberry sauce, sweet potatoes and pies.
"If we get stranded on the side of the road, we are not going to starve," John Lawson said.
In Tennessee, Pam Walker and her family of five arrived in Nashville early Wednesday after a more than seven-hour drive from Muskegon, Mich., to visit her son.
"It's cheaper and it's also a ride we're familiar with," said Walker, who was meeting her son at a restaurant for breakfast.
Carriers had been counting on holiday travelers more than usual because travel has been so weak the rest of the year, said Stifel Nicolaus analyst Hunter Keay. The AAA predicts there will be a 6.7 percent decrease in air travelers this holiday compared with last year.
That doesn't mean fewer sardine-packed planes. Carriers have cut the number of aircraft in service, ensuring full planes. And with extra fees to check baggage on most carriers, many travelers are likely to bring as much as they can on board. So add battles for overhead compartment space to the list of potential aggravations.
Some travelers were lured to fly at the last minute by airline bargains. Danny Cruz, 30, a bookstore employee from Atlanta, was facing a holiday apart from her mom who lives in Orlando because airfares were too high. But they took to the Internet and scored a last-minute deal -- from airlines scrambling to sell open seats.
"Suddenly one day it went from almost $400 to almost half the price," Cruz said.
So far, air travelers found quick lines and little aggravation. The world's busiest airport, Hartsfield Jackson Atlanta International Airport, is bracing for a rush of 1.7 million holiday travelers -- in line with the holiday period last year, general manager Ben DeCosta said.
Matthew Paulk, a student from New York City, said he braced for the worst before he arrived at the Atlanta airport.
"I expected it to be hectic -- people losing their bags, tripping, dropping stuff, arguments," he said. "But it was really good. It wasn't what I expected."
Maureen Miles said her family may not be among those switching back to planes once the economy starts improving -- and not only because travel by train is easier on their pocketbook. Her kids, she said, have enjoyed the chance to get a good look at America beyond New York at a train's pace.
"Money aside," she said, "traveling by train is an adventure."
