The holiday season isn’t about shopping and gifts. 【1】 However, holiday travel can be more expensive than gifts. Fortunately, the following tips will help keep your travel spending under control.

Plan ahead. The earlier you book your travel, from airfare to hotels, the easier it is to find good deals. 2 Your best prices on airfare come when you book three weeks before the plane leaves for domestic(国内的) flights. For international flights, consider booking 30 days in advance. Many experts point out that you should book travel between one month and three months out for high-traffic holidays.

Book your air travel on cheaper days. Traveling by air on Tuesdays and Wednesdays often costs less than on Fridays and Sundays. During the holidays, it’s not just about a specific day of the week. You also need to consider the days surrounding the holiday but days immediately before and after a holiday can be expensive. One of the best ways to save is to plan your air travel on the day of the holiday. 3

Consider traveling overnight. Red-eye flights and overnight flights often cost less than those at more convenient times. 4 Traveling overnight can help you avoid a night in the hotel, as well as save your money on travel to your destination.

5 You can’t bring liquids with you on the airline, but you can bring sandwiches and other snacks. When you’re on the road, you can buy food at local groceries to make your own meals, especially if you have access to(可使用) a microwave.
