  • This month, prices remain in-line with September as domestic flight prices decrease 0.1% to $211 round trip.

  • October flight prices are projected to reach the lowest levels since before 2013. Compared to the same time last year, flight prices are projected to be down 3.1%.

  • Prices will remain low through the end of October before spiking for a short period in November over the Thanksgiving holidays. Prices will drop again in December and January before rising in the Spring to meet spring break demand.

  • Jet fuel prices fell 6.3% in the most recent month of reporting data compared to the previous month, to $1.80/gal.

  • Looking for an international getaway? Asian destinations, including Bangkok, Seoul, Osaka, and others are on sale this fall.

This month, we project domestic round-trip flight prices to remain in line with September prices, and are notably the lowest they have been in 6 years. Prices will remain low through the end of the month, spiking in November for a short period over the Thanksgiving holiday. Jet fuel prices fell 6.3% in the most recent month of reporting data compared to the previous month, to $1.80/gal. For Americans looking for an international getaway, Asian destinations are notably on sale this month.

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.
