Searching for airfares often seems like a game that passengers are bound to lose.

Prices change from day to day, even minute to minute. Looking through various websites for the best deal can be a big challenge. Even when you do book, there’s no guarantee that you are going to get the best price.

“You just don’t know when to pull the trigger. It’s not like buying anything else I can think of,” said George Hobica, founder of Airfarewatchdog. com.

Harriet Levy paid $ 179 for a recent round-trip flight on American Airlines between New York and Fort Lauderdale, Florida. Sitting just one row behind her, Shirley Harrison paid $ 215. A few rows back, Ellis and Dianne Traub paid $ 317 each. There were at least 12 fares on the flight, ranging from $ 169 to $ 360.

“There’s no reason for it,” Harrison said.

Fares can vary significantly in just a few hours. One Delta flight from New York to Los Angeles jumped from $ 755 to $ 1,143 from a Friday to Saturday in late April, and then fell to $ 718 on Sunday.

The flight was one of a dozen the Associated Press（美国联合通讯社）followed over three months for a vacation between July 16 and 22. The number one finding: avoid booking tickets on weekends. It’s the most expensive time to buy.

There’s no way to guarantee the best fare. But before booking, travelers should pay attention to this additional advice:

● Book on Tuesday, Wednesday and Thursday. That’s when airlines most often offer sales.

● Buy in advance, but not too early. The best time is four to six weeks before traveling. In general, prices for any given flight are the highest when tickets are booked eight to ten weeks and two to three weeks in advance.

● Make use of social media. Airlines are giving more benefits like exclusive（专有的）sales to travelers who interact（交流）with them on Twitter and Facebook. Those specials are often gone within hours.

● The so-called discount airlines — JetBlue, Air-Tran, Southwest and Frontier — adjust their fares less frequently than other airlines, so you can feel more confident that the price will stay the same. But their prices aren’t always the lowest. Researching multiple airlines’ fares is the only way to get a good deal.

Most of us look forward to the weekend as a time to relax.

But even though the Sunday scaries are common, 【小题1】. Here’s how experts say you can ease your end-of-weekend anxiety.

1. Structure your Sunday.

“Structure can be a best friend when feeling the Sunday scaries,” says Ficken. “Instead of sitting on the couch and watching the clock, go do something that you enjoy. “You might still get whiffs of that sense of dread, but that feeling is harder to hold on to when you’re engaged in something that makes you feel good, she says.

Anxiety is a normal human experience, and one of the main ways to manage it is to identify your personal triggers. “Try to pinpoint what’s really causing you to dread the week,” Goff says. “Is it a deadline, meeting or presentation?” Even if there’s not a single reason behind your Sunday anxiety, organizing the stress you expect from the week ahead into bite-sized chunks can help make it all more manageable. “【小题3】.” she recommends. “One list for tasks that need to be completed immediately, another for tasks that are less urgent, and a final list for tasks that you’d like to complete at some point.”

It’s a form of reframing your thoughts: Instead of focusing on the awful things you expect from the week, build excitement over a coffee or lunch date with a friend you’ve been meaning to catch up with. 【小题4】.

5. End your Sunday with the right energy.

Make Sunday nights about doing something for yourself, to counteract the anxiety you’re feeling about Monday. Maybe that means planning some favorite foods to enjoy while watching football. Or maybe you go all in for some self-care. “This is an opportunity to give yourself proper wind-down time. 【小题5】, and leave the work emails for Monday morning.” Warren says.
