The U.S. Bureau of Labor statistics are out and it shows some massive inflation in airfare over the past year, but is that all there is to it?

U.S. Bureau of Labor releases new statistics for April 2026… and airfare is ugly

The latest U.S. Bureau of Labor statistics paint an ugly picture for many services, confirming an inflation concern that’s ramping up. CPI Index isn’t a perfect model, but the premise is simple: follow a basket of goods over time and chart out its price. In doing so, you can get a rough sense of how prices have changed. In reality, it’s not that simple. The same goods don’t have a fixed price by location, there is no perfect measure for changes in quality, and might not reflect your own personal usage pattern.

One of the more impactful changes in the April 2026 report is to airfare, which has gone up 20.7% year-over-year and up 6.3% over the last month.

The easy comparison is against the inflation rate for all items, which sits at +3.8% year-over-year and +0.9% over the last month. That’s a large increase for all items and it’s clear that airfare is bringing up the average.

But is that the only conclusion?

Always review the methodology before arriving at conclusions

Let’s take a closer look at the assumptions made, which can help indicate how we need to interpret the data. The U.S. Bureau of Labor provides the following detail:

• Airfare represents a sample of flights, not all commercial flights
• Excluded from the sample are helicopter trips, trips on intra-Alaska carriers, and trips considered “business travel”
• Both domestic and international airfare is included from each selected city in the sample
• The same quote methodology is used consistently month-over-month so that airfare represents a basket of how customers book travel
• 80% of quotes include pricing for one checked bag but pricing for carry-on bags is not included
• Pricing includes taxes, fees, and surcharges
• The “vast majority” of quotes are for discounted economy fares and very few are for full-fare coach or first class
• Discounts for frequent flyer loyalty programs are not included

So, let’s keep in mind the following, as it might be relevant in interpreting the data:

• Airlines famously increased rates for checked bags in late March / early April 2026 and this increase will now be reflected in the results
• The more ultra low cost carriers (ULCCs) there are flying routes, the lower fares will appear (R.I.P. Spirit) since ancillary fees like carry-on bag surcharges aren’t captured by this methodology
• Along those same lines, the most common fare chosen might just be basic economy
• There can be considerable selection bias depending on the departure cities chosen
• The surge in premium travel pricing is only going to be partially reflected in here since most quotes represent discounted economy travel

So, what does the data actually say?

Off the bat, we know that airlines increased bag fees as high as $50 for the first checked bag across the board, up from about $40. This increase should now be in there for April but wasn’t baked into March. That alone is a 25% increase, which helps bring up airfare to its 20.7% increase over the past year and 6.3% increase since March.

The other bogey sitting over airfare right now is the oil situation in the Strait of Hormuz. It should come at no surprise now that oil and fuel costs are soaring. The “fuel oil and other fuels” category in the CPI report comes in at a 31.9% increase year-over-year. The change is only up 1.6% in one month, suggesting it’s partially baked in already. The cost of fuel is an important variable for airlines, and when fuel soars, airfare will follow.

Combined, those two items alone could account for much of the change. The collapse of Spirit Airlines–and the removal of low fares–won’t be felt in the data until we see the May 2026 report. However, given how Spirit had been winding down operations over time, it might not be as pronounced on a month-over-month basis.

Additionally, the year-over-year impact is going to pick up on Southwest famously moving from a model where bags fly free to one where it costs money to check a bag. It’s unclear from the methodology how many quotes are on Southwest, but it is one of the four largest airlines in the United States. If the quote volume mirrors market share, there should be a decent impact from this.

Seasonality in the data

Conveniently, the U.S. Bureau of Labor provides some data over the past 10 years and plots it on a chart. The data is indexed all the way back to the years 1982-1984 when it was assigned the value of 100. That lets you see how airfare has proportionally changed since then.

First, just take a glance at the graph below. Notice how there’s a clear pattern of a relative bump up in price about a third of the way into the year?

That bump, and typical drop the rest of the year, suggests there is some seasonality to the results. Airfare seems to peak in Q2 before dropping the remainder of the year. What’s not clear is if it’s caused by a bias in the results (does the methodology somehow capture some surge in summer travel or is it all in the cities chosen?). We can normalize out the impact of seasonality in this month’s results by comparing the average airfare by month against the overall average.

For April, airfare tends to be 4.6% above average. This is relevant if we want to compare April 2026 against the average from 2025. In 2025, the average airfare was 256.118. Straight math would tell us that April 2026 is 20.5% higher than last year (308.527/256.118 – 1). However, adjusted for seasonality, it’s only 15.2% higher (1.205/1.046 – 1).

The first four months seems predictive for the overall year

The average of the first four months appears to be a good estimate of where the overall average airfare will go. That’s because February and March need no seasonality adjustment and January generally offsets most of April. We can summarize it in the table below.

Remove the years impacted by the COVID pandemic (2020, 2021, 2022) that really destabilized the airfare pricing model. You could make the argument that the beginning of 2023 was still in a corrective period. Outside of those years, there’s not much variance between the first four months and the annual average.

Prior to 2026, annual airfare was allegedly dropping but we don’t buy it

According to the 10 years of data, the annual average airfare was trending downwards. However, that seems to be changing with the latest data. If we assume the above holds true, we would expect the annual average airfare for 2026 to land somewhere around 287.641. That would be the highest price in at least 10 years. According to the data, airfare was on a downward trend (aside from the instability of the COVID-impacted years).

It’s hard to tell if this is actually true because the exact quote methodology isn’t published. It could be that the existence of more ULCCs in the market helps push down the average. As more carriers move to a model of unbundling, results over a large timeline get clouded. What the U.S. Bureau of Labor does publish about the methodology clearly states that they don’t include the price of hand baggage. That means those ‘basic’ fares, which seem to be what the methodology focuses on, aren’t on an apples-to-apples basis with prior years.

If you’ve been flying the same airline over the past 10 years and saved your receipts, you’d probably notice an uptick in pricing. Thus, while the data claims airfare is coming down–something the CEOs will undoubtedly use to justify raising prices because look how cheap flying is–it fails to show how unattractive discounted economy flying has become.

What’s the real takeaway from the report?

Airfare is up since the start of the year and compared to the average from last year. Some of this is driven by increased checked bag fees at the end of March / beginning of April, which appears in 80% of the quotes in this data. A large chunk of this also can be explained away by the price of fuel and energy, which is surging. Outside of those two variables, airfare pricing in Q2 always seems inflated, though it’s hard to identify why.

Together, we’d say that we shouldn’t be shocked by the increase in airfare pricing. That’s why we’re not making the percentage change the headlining title of the post. Historically airfare is elevated this month anyways and with external pressures, we’d be surprised to see a normal April. It’s just hard to piece together if it’s the methodology causing the April and Q2 spike or if airlines just ramp up pricing for the normally-busy summer travel period.

However you slice the data, you’ll want to make sure you’re looking at it with a critical lens because it’s easy to come to false conclusions about what the data is actually saying.

Is there something concerning you’re seeing in the data that we missed?
