Airfare expected to peak in June and then decrease through the summer

Patrick Surry - Jun. 1, 2017


  • This month, we project a 2.0% increase in domestic flight prices to $258 from $253 in May roundtrip as demand continues to pick up as people begin booking their summer travel

  • Flight prices are expected to be up 5.2% compared to the same time last year

  • We're forecasting that prices will begin falling after next month for the next three-four months with prices bottoming in October at $223

  • Jet fuel prices fell 11.3% in May, decreasing to $1.34, still approximately half the recent high in Feb 2014

  • Driven by summer travel to Europe, US domestic capacity will increase 2% from the preceding month

  • Foreign low cost carriers will increase capacity to the United States by 61% in June 2017 (change from June 2016), largely driven by European airlines WOW and Norwegian

Prices are expected to be up about 5.2% compared to the same time last year, but down 4.3% compared to two years ago. The price of jet fuel decreased about 11.3% last month but still approximately half the price of early 2014. Flight prices are expected to peak, which is normal for the season, as travelers move past booking their spring travel into summer. We're projecting that domestic airfare will fall beginning in July and bottoming in October to $223.

Figure 3: A longer range view shows that jet fuel prices have dropped to 2009 levels. Airfare has been on a controlled downward trend for the past 3 years and is starting to reflect 2009 price levels.

June Capacity Trends

Both US and foreign major carriers will offer similar capacities as they did last year (YoY changes range from 1-4%). LCC capacity over the past year, however, has drastically expanded; US LCCs show a YoY capacity increase of 15% and 10% in domestic and international markets respectively, and foreign LCCs show an impressive 61% YoY capacity increase.


Our Consumer Airfare Index combines search data for every origin and destination in the United States, providing a near real-time estimate of overall airfare prices - unlike other comparable indices that can lag by several months.

Our Consumer Airfare Index represents the price of tickets available for purchase in a given month, not necessarily for travel in that month. Since travel prices are represented in both time dimensions -- time of purchase and time of travel -- it can be difficult to interpret price dynamics. We use date of purchase because it reflects the price consumers are paying at a given point in time, and we report it alongside the typical advance purchase date to give an idea of how these prices translate into travel dates.

Other indices simply take the average of all fares to represent overall price which skews the results toward expensive fares and can give an unrealistic impression of the true cost of flying. We instead use what we consider to be a "good deal" for each route to reflect what consumers should reasonably expect to pay.

Since our index is constructed and forecasted at the origin-destination level, we can also provide comparable estimates for any combination of routes and extract insights on pricing not only across time, but also across different markets. We use monthly passenger data from the Bureau of Transportation Statistics to ensure that each domestic route is properly represented in the final index based on its share of total passengers.

When predicting future prices, we also consider a few key features of airline pricing. First, prices within a given route will fluctuate with the number of passengers.

Second, prices change predictably with the seasons, especially during the peaks of summer and holiday travel. Of course, much of this variation has to do with increased demand - but in peak travel seasons, airlines can raise prices not only because there are more people interested in travelling, but also because the average traveler is willing to pay more for their summer vacation or trip home for the holidays.

Finally, changes in prices may persist, especially if there are underlying conditions pushing prices up or down, as these effects may be spread over several months. Conversely, the opposite may be true - after a big price increase or drop, fares are more likely to change in the opposite direction in future months. Since dynamics like these and the above aren't always consistent, we evaluate future prices at the origin-destination level to capture the unique properties of pricing for different routes.

Of course, predicting the future is no easy task, and many factors that influence pricing are simply unforeseeable. However, by exploiting the factors that are predictable, like trends in passenger distribution, seasonal variation, and recent price activity, it's possible to extract insights about the near future of pricing.

The capacity section looks at total scheduled seats across major carriers and low cost carriers (LCC's). US Domestic Flights includes all scheduled seats on flights within the United States and US International Flights includes all scheduled seats on flights between the United States and destinations outside of the United States. Change from preceding month is calculated by comparing scheduled seats for flights in June 2017 with flown seats in May 2017. Change from June 2016 is calculated by comparing scheduled seats for flights in June 2017 with flown seats in June 2016.

Historical Analysis and Comparisons

Our index generally tracks the Bureau of Labor Statistics' Airfare Consumer Price Index, which is a related aggregation of the prices consumers pay to fly but is more strongly influenced by more expensive business-oriented travel. It's also released on a more delayed schedule than our index.
