Domestic roundtrip airfare rose 8.7% in May to $244, three percentage points above our forecast. This is the largest percentage increase we've recorded since we began tracking three years ago.
Although oil prices have recovered about 30% above their recent floor, jet fuel still costs less than it has in more than a decade.
We project airfare to peak in June at $249, down 9.2% below last year's peak, and 17% below the peak two summers ago.

Consumer Airfare in June
Prices rose almost 9% for the typical round-trip domestic flight in May, driven by increasing summer demand and recovering oil prices. May prices are down 10.5% from last year and about 18.8% compared to two years ago. Airfare is currently at lower seasonal levels than they've been since 2010, although jet fuel is trading at prices not seen since 2004.
We're projecting consumer airfare will top out at $249 in June, a 2.2% increase from May. This would still be 9.2% below last year's peak, and 17% below the peak two summers ago.

Figure 2: Recent jet fuel prices compared to consumer airfare. Fuel prices have recovered about 30% above their floor, apparently leading to accelerating airfare price increases.
Figure 3: A longer range view shows that jet fuel is still cheaper than it's been in more than ten years, and airfare is still inexpensive on a seasonal basis.

Mapping Prices by State
To see how airfare from your state stacks up against the national average, our our interactive Consumer Airfare Index map and enter your home airport in the box.
Figure 4: Average price to fly to each given state.
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.
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.
