American Charged Solo Flyers More on a Third of the Flights Checked. On Delta, Alaska and Southwest, It Was Zero of 3,000

A new airfare check shows the penalty for flying alone survived last year’s backlash at two of America’s five biggest airlines, and one of them is far ahead of the other.

Thrifty Traveler’s analysis, published Oct. 30, 2026, covered 5,000 domestic nonstop one-way flights, 1,000 each on five airlines, collected that week on randomly selected routes for the next 11 months. American Airlines charged solo passengers higher fares on 33.5% of its flights, by an average of more than $90.

United did it on 10.6%, by just over $64 on average. Delta, Alaska and Southwest did not do it on a single one of their 1,000 flights each.

That is one outlet’s sample, and an earlier count by The Points Guy found the practice far less alarming. The two are closer than they look.

Why a $496 American Ticket Drops to $155 With a Second Passenger

Thrifty Traveler’s sharpest example is American from Miami to Charlotte in December: $496 one way for one passenger. Add a second, and the same main cabin fare falls to $155 apiece, so three people pay less than one.

A basic economy fare of about $100 also appears, but only when the search includes at least two people. A solo search on Google Flights or AA.com never shows it, Thrifty Traveler says.

The switch is one line in the fare rules. Thrifty Traveler quotes the cheaper fare as requiring that the traveler “must be accompanied on all sectors in the same compartment by at least 1 adult.”

American calls its version Multi-Pax Fares, for eligible passengers who book and travel together, View from the Wing’s Gary Leff reported on Nov. 1.

This reverses how airline ticket pricing normally behaves. Airlines sell seats in fare classes at different prices, so if one seat is left at the lowest fare, a search for two gets pushed to a higher one. That is the usual way a gap appears, Thrifty Traveler says: pairs paying more per person, not less.

American has not explained itself. It did not respond to Thrifty Traveler’s several requests for comment, and United declined. The outlet’s explanation, which it labels a guess, is that lone flyers are more likely to be business travelers on an employer’s budget.

Is It a Solo Penalty or a Discount for Pairs?

Former American CEO Doug Parker argued the second reading in June 2025. “The net result of this is not that the person got penalized. The tickets for two are discounted,” he said on a podcast, as Thrifty Traveler reported.

Thrifty Traveler’s new data offers three points against that. On American, the affected share hits nearly 60% of flights to and from Philadelphia and 65% at Charlotte, yet the practice is far less common at Dallas-Fort Worth, its biggest hub.

Second, on both American and United it is far more common on routes where the airline has a monopoly than where it faces two or more rivals. A real discount, the outlet argues, would make more sense where there is competition.

Third, on American routes where the gap came and went by date, group fares were also slightly higher on the days it appeared. Philadelphia to Rochester flights logged on three dates averaged roughly $307 per passenger for one traveler or two, except Dec. 8, when one traveler paid $434.

Thrifty Traveler concedes that United’s version sometimes does look more like a companion discount.

The Points Guy Counted 3,817 Routes and Found Far Less

The Points Guy and Points Path ran their own count, published June 27, 2025. They looked at popular domestic routes on the same five airlines, for one travel date chosen at random: July 18, 2025.

Out of 3,817 route combinations, solo passengers paid more on 271 and paid less on 235. The rest matched, about 87% by our arithmetic, and the writer came away “fairly reassured.”

Pool Thrifty Traveler’s five airlines the same way and the gap narrows: 441 of 5,000 flights, or about 8.8%, against 7.1% for The Points Guy. That is our calculation, and the two are not a clean trend, because the samples differ in date, routes and method.

Three differences matter. The older count published no split by airline, so it could not show American pulling away. It stuck to busy routes like New York to Los Angeles, while Thrifty Traveler says the penalty clusters where an airline has no real rival.

And the older count measured something the new one does not report: how often solo flyers pay less. The reverse case was nearly as common, 235 against 271.

Thrifty Traveler’s own history also complicates its “getting worse” line. In a June 2025 check of 200 American one-ways, Charlotte ran 66% and Philadelphia 60%. The new figures are 65% and nearly 60%, from a different sample.

What has changed is the reach. In June 2025 the outlet saw American’s gap only on domestic one-ways. It now reports it on some domestic roundtrips, and at American occasionally on short international trips to Mexico or the Caribbean.

What Solo Flyers on American and United Should Do

The seat does not change. American flew 303 Boeing 737-800s, its largest single type in a fleet of more than 1,000 mainline jets, at the end of 2025, and a main cabin seat on one is not better because someone else booked with you.

So a single search is no longer enough. Price the trip for one traveler and again for two before you buy, which is also what The Points Guy advised after its count.

Buying two tickets and canceling one is not a clean fix. Leff writes that American’s published instructions say a cancellation leaving one passenger on a multi-passenger fare means the remaining ticket has to be repriced to an eligible fare. He says he would still try splitting the record.

Pairs should check too, since the reverse happens. In its 2025 count, The Points Guy found American charging a couple about $68 more per ticket than a solo traveler from Philadelphia to Orlando, a case where two separate bookings would have been cheaper.

Not everyone caught is on a corporate card. Thrifty Traveler lists flyers heading to a family emergency and spouses who leave a day or two apart, at a time when it puts airfare up more than 25% in a year.

Delta Walked Away. American Never Stopped

Thrifty Traveler first reported the practice in spring 2025, across American, Delta and United. Delta briefly used it on select domestic routes and reversed course as it became national news, and the outlet says it never came back.

United also pulled back in 2025, then came in at 10.6% in the new check. American, the outlet said in June 2025, “has never stopped.”

The federal government is looking at airline pricing, but at a different question. The FTC’s orders announced Oct. 28, 2026 asked Delta, United, JetBlue and non-airline companies whether prices vary from person to person based on factors like personal data. American was not among those named, and the orders request information rather than find wrongdoing.

A solo fare does not need personal data. It only needs to know how many passengers you typed into the search box, and the rule that decides it sits in fare text that Thrifty Traveler says virtually no traveler ever reads.
