Flying frugally

Before the end of the year, take inventory of your frequent flier miles. Claim credit for any missing miles and decide if you can top off—with an extra flight, hotel stay or mile-generating purchase—accounts where you are close to getting elite status perks for the following year.

When shopping for new flight reservations, sign up for fare alerts, enlist helpers such as Kayak's price forecasting tool and remember the "24-hour reservation requirement" put into effect in January 2012 by the U.S. Department of Transportation. The rule requires carriers to hold a flight reservation for 24 hours without payment, or allow a reservation to be canceled within 24 hours without penalty if the reservation is made one week or more ahead of the flight's departure date.

"If you see an airfare you're comfortable with, book it," said Kayak spokeswoman Maria Katime. You can continue your research and, if you find something better, go back and cancel.

Reasonable rental cars

When it comes to cars, reserve once you know your dates and have done some shopping, but recheck prices closer to the time of travel. "Prices can drop last-minute, depending on the actual availability of cars versus what the companies anticipate," said travel expert Carol Pucci, who saved more than $100 with this method on the Big Island of Hawaii. "It was easy to do because I hadn't prepaid, which is hardly ever a good idea given the chances of prices falling," said Pucci.

To make sure a rental car company doesn't charge you for scrapes, scratches or dings already on the car you're issued, "take pictures of the car before you drive it away and when you return it," said Joe Brancatelli, publisher of the business travel website Joe Sent Me.

"Rental firms are getting extremely aggressive about these charges and since the cars in the fleet are older these days than they used to be, there's more of a chance you'll be given a car with a ding and/or scratches," he said.

Honing in on hotel deals

Sign up for the frequent stay program of any hotel you visit to take advantage of free perks that can include complimentary breakfast, free Wi-Fi and welcome amenities such as cheese plates and bottles of wine for even the first-time guest.

Research room rates and hotel property reviews online, but as a final step, call the hotel you've chosen. "Once I narrow down my hotel choice, I call the hotel to see if they have any better offers then what I see online," said Rob Connors, assistant vice president of marketing for National Car Rental. "Your membership in a club or association might get you an added discount, and many times hotels offer special rates for suppliers calling on nearby companies."

It's also a good idea to check city tourism sites for short-run, special promotions.

Some cities have destination marketing funds and packages designed to generate room sales during off-seasons. The inaugural Hotel Week LA runs from Nov. 29 to Dec. 14, and in 2015, more than 30 Manhattan properties are participating in the fourth New York Hotel Week from Jan. 3 to 18. The programs offer significant discounts rate for some of each city's top, usually very pricey, properties.

Vancouver's "Be Vancouver" promotion gives guests $125 American Express prepaid gift cards for bookings made by Nov. 16 for stays through Feb. 28, bringing rates in some upscale hotels down to less than $60.

"The offers coming from that program are the best we have on offer," said Jim Mockford, general manager of the Listel Hotel. "They're highly targeted in regards to time frame, so you have to be quick and flexible. So it's always a good idea to put your name on the mailing list of your favorite hotels. You'll hear about some great deals that you'll never see anywhere else."

Choosing travel gear

To get the best bang for your buck when shopping for travel gear "make a list of three to five 'musts' for your new bag and prioritize these as you do research," said Michele Marini Pittenger, president of the Travel Goods Association.

"The manufacturer's warranty policy can be an indicator of durability, but be sure to check the dimensions of new carry-on bags to avoid getting dinged by extra charges when flying," she said.

When to use a travel agent

Modern online booking tools and mobile apps make it easy to research and reserve much of your own travel. But the customer services of a travel advisor who can quickly reroute and rebook you when there's a travel snafu can come in handy.

"When it's a trip that mattersfamily vacations, celebration travel, a destination you want to experience rather than 'see'that's when you most need a travel advisor," said Matthew Upchurch, chairman and CEO of Virtuoso, a network of luxury travel agencies. "Not only will they save you precious time, they can save you money with negotiated hotel benefits and extensive firsthand knowledge to ensure that you get exactly what you expect from the trip."

Boarding the bus

"Bus travelers typically save 50 to 55 percent versus the train and 55 to 73 percent versus flying," said Joe Schwieterman, a professor at DePaul University in Chicago and author of the Traveler's Tradeoff study comparing intercity bus, plane and train fares across the United States.

"The 'sweet spot' for bus travel involves trips between 125 and 300 miles. Driving can be tedious, but air travel is often not cost effective," he said.

When to book the bus?

"As early as possible," said Megabus spokesman Mike Alvich. "Generally customers booking 30 to 45 days in advance will see the greatest savings, but even last-minute trip tickets are still very affordable in comparison to last-minute airline travel or even the cost of filling the gas tank of your personal vehicle."

Smarter destination choices

You may not have much choice where business trips take you, but you can save money on leisure trips and avoid crowds by heading for South Africa, Shanghai, Uruguay, Portugal or some of the other "best-value" destinations on Lonely Planet's Best Travel 2015 list.

Choosing "almost-as-good" alternatives to classic experiences in more expensive cities can also save cash.

"European cities are stuffed full of amazing historic buildings and churches that can be seen and explored for free without the crowds of big-name things," said Lonely Planet's editorial director, Tom Hall. "Gorilla trekking might be an unforgettable experience in East Africa, but looking out for chimpanzees and smaller primates can be much more fun and is certainly easier on the wallet."
