Recent research from Expedia and Airlines Reporting Corporation shows Sunday as the day when airfare discounts are most likely. Their joint report, New Heights for Air Travel, studied 2016 global air-travel data to predict the best days to buy tickets.

Tuesday is cherished by some as a day to get good airfare deals, although this day isn't really the best any more, according to airline data research noted in the Expedia study.

Friday as the worst day to book flights

These are four of the biggest deal zones of the year.
  • Early December: Typically the first two weeks of December, sandwiched between the big peak travel periods of the U.S. Thanksgiving holiday, and Christmas/New Year's
  • January: Most of the month, once the New Year's travel rush subsides generally around Jan. 7
  • Spring: Not as cheap as January; does not apply to traditional Spring Break weeks in March/April
  • Fall: This deal zone usually gets underway in late August; there is usually another price drop in October

For general year-round travel, the lowest average domestic airfares are usually found 2-4 weeks prior to departure while international airfares are at their lowest point 2-3 months out. Here are some additional travel secrets:
  • Don't book too early. The average domestic fare found six months before a departure date was 2% higher than the fare found 2-4 weeks out.
  • Travelers planning a week-long domestic trip should depart on a Saturday and return on Monday to score the cheapest airfare (roughly 16% lower than average).
  • For international week-long trips, we recommend departing on a Tuesday and returning on Wednesday to save some $$. These flights were 21% lower than the average.

Tips for getting better fares:
  • When to book:
  • Always buy your tickets at least 14-days in advance of your departure.
  • According to, Wednesday is the best day to get a deal on an airline ticket. Do not book over the weekend. Wednesdays is when arilines typically release internet-only fares.
  • Days to travel:
  • says, "Fridays and Sundays are the busiest days of the week to travel, which also makes them the most expensive.
    Midweek flights Monday through Thursday tend to be cheaper, and red-eye or midday flights can also cost less.
  • says,
    • Cheapest Travel Days are usually: Tuesday, Wednesday and Saturday
      But check other days, sometimes Monday may be cheaper.
    • Most Expensive Travel Days: Monday and Friday
    • Cheapest Time of Day to Travel: Evening (except on Friday and Sunday)
  • The difference between weekdays and Sunday seemed to be more for major cities (e.g. San Francisco) than smaller cities (e.g. Sacramento) see below.
  • Most of the Best Fares sites allow you to check multiple dates with a button on the search page. Travelocity seems to do this best.
  • Holidays: Thanksgiving, New years, the Sunday before memorial day or labor day are also usually cheaper.
  • The rule about staying over Saturday doesn't apply any more.

At the top of the list they will an indicator with something like:

I did some sample fare checks for Newark, NJ to Sacramento, CA:

  • Wed to Wed in 2011 was the same as Sun to Sun on both United and Contintal.
  • Wed to Wed in Sept. 2010 was $50 less than Sun to Sun on United and the same on Continental.
  • United and Continental were lowest on Orbitz and Kayak, Continental showed a lower pice on their web page but when you read the fine print they did not include about $40 in fees. Kayak and United web sites included the fees.
  • Newark to San Francisco was about $85 less with United on Wed to Wed than on Sun to Sun.
    It was less than Sacramento on Wed. and more than Sacramento on Sunday.
