Wendover’s “Worthless Airline” Claim Fails Its Own Financial Test
Wendover Productions has identified something genuinely important: American, Delta and United have built enormous financial businesses around frequent flyer points. But its most dramatic conclusion—that the airlines themselves are worth less than nothing—is not established by the evidence.
The video makes two fundamental mistakes. It compares incompatible financial valuations as though they were equivalent, then uses an incomplete revenue calculation to portray American Airlines' passenger operations as loss-making. Together, these errors turn a compelling explanation of airline financial engineering into a much stronger claim than the numbers support.
The loyalty businesses are valuable. That does not make the rest of the airline worthless.
Three valuations that were never directly comparable
The video's central comparison uses three figures:
- United MileagePlus: $21.9 billion.
- Delta SkyMiles: approximately $26 billion.
- American AAdvantage: up to $31.5 billion.
Wendover presents these as similar financial disclosures. They are not.
United's June 12, 2020 SEC filing explicitly states that its $21.9 billion valuation was calculated by multiplying MileagePlus Holdings' 2019 EBITDA by 12. The filing also disclosed a commitment for up to $5 billion in secured financing against the loyalty business. This was a valuation derived from an earnings multiple in a financing transaction, not the price established by an actual sale. (United's SEC filing.)
SEC
Delta's $25.931 billion figure came from something different. On Point Loyalty published its 2020 ranking on January 29, 2020, using a proprietary algorithm incorporating more than 50 variables. It was an independent consultancy estimate, not a financial disclosure by Delta. The same report valued American's AAdvantage at $23.44 billion and United's MileagePlus at $20.172 billion. (On Point Loyalty's original report announcement.)
PR Newswire
American's $31.5 billion figure is even more revealing. Its June 2020 SEC prospectus disclosed a third-party appraisal of between $19.5 billion and $31.5 billion for its domestic AAdvantage loyalty assets. The company was seeking approximately $4.75 billion in secured government financing. Wendover selects the highest possible appraisal figure and presents it as the program's valuation. (American's SEC prospectus.)
SEC
Three different methodologies, different dates and different definitions of the assets being valued. One is a proprietary consultancy estimate, another an earnings multiple, and another the upper end of an appraisal range.
That is not a comparable valuation exercise.
Market capitalization is not enterprise value
There is a more fundamental accounting problem.
Wendover compares these program valuations against the airlines' stock-market capitalizations and calculates the apparent negative value of their flight operations.
But market capitalization measures the value of shareholders' equity. An EBITDA-based enterprise valuation measures the value attributable to the business's capital providers, including debt holders.
The distinction is basic corporate finance. The CFA Institute explicitly distinguishes enterprise-value multiples from equity-price multiples and explains why EBITDA-based valuations must account for the company's capital structure. (CFA Institute, Market-Based Valuation.)
CFA Institute
United illustrates the problem.
Its June 2020 financial statements reported $18.8 billion in long-term debt. The company subsequently issued another $6.8 billion in debt through the MileagePlus financing.
Those obligations matter when comparing the value of a business against the value of its shareholders' equity. The video's comparison does not provide the necessary enterprise-value calculation or a reconciliation of the liabilities attached to the loyalty business.
SEC+1
Even accepting every market-cap figure in the video, subtracting a loyalty-program valuation from equity market capitalization does not establish the value of the remaining airline operations.
The conclusion that the flying business has negative value is therefore unsupported.
American Airlines was not losing money per seat-mile
This is the clearest factual problem in the entire presentation.
Wendover argues that American Airlines was losing approximately half a cent for every seat-mile flown in 2018.
Its calculation uses:
- Passenger revenue per available seat mile: 14.42 cents.
- Operating cost per available seat mile: 14.85 cents.
- Apparent loss: 0.43 cents.
The problem is that the first figure measures passenger revenue only, while the second measures total operating costs.
American's own 2018 annual report provides the missing figure: total revenue per available seat mile was 15.79 cents.
That means the correct comparison is:
American Airlines, 2018 Cents per available seat-mile Passenger revenue (PRASM) 14.42 Total revenue (TRASM) 15.79 Total operating cost (CASM) 14.85 Total revenue less operating cost +0.94The difference is not subtle. American generated more total revenue per available seat-mile than it spent operating those seats.
SEC+1
The omitted revenue included $1.013 billion in cargo revenue and $2.852 billion in other operating revenue. The latter included $2.352 billion in loyalty marketing-services revenue.
American's 2018 financial statements also reported:
- Total operating revenue: $44.541 billion.
- Total operating expenses: $41.885 billion.
- Operating income: $2.656 billion.
- Pre-tax income: $1.884 billion.
The airline was profitable at the consolidated operating level.
SEC
This does not prove that passenger transportation would have been profitable without the loyalty business. That would require a proper allocation of shared expenses and loyalty-related revenues.
But it destroys Wendover's particular calculation. Passenger revenue alone cannot be compared with all operating costs to establish that the airline was losing money.
The $4.2 billion figure is revenue, not profit
The video also attributes American's $1.9 billion pre-tax profit to $4.2 billion in frequent flyer program revenue.
There is another missing distinction.
American president Robert Isom told investors during the October 25, 2018 earnings call that AAdvantage had added $4.2 billion in revenue during the first nine months of 2018. It was not a statement that the loyalty program had generated $4.2 billion in net profit. (American's Q3 2018 earnings call.)
The Motley Fool
The subsequent full-year 10-K separately reported $3.219 billion in loyalty travel revenue and $2.352 billion in loyalty marketing-services revenue.
Those are revenue categories. They do not establish how much profit the program generated after its associated expenses and obligations.
SEC
Wendover has not demonstrated that AAdvantage alone generated American's entire pre-tax profit.
The distinction matters because revenue is not profit, and a business cannot be valued accurately by treating every dollar received as a dollar earned.
An error that has travelled into legal scholarship
There is an uncomfortable sequel.
A 2024 Vanderbilt Law Review note, Financialization of Flyer Miles, repeats the same American Airlines calculation, using the 14.42-cent passenger revenue figure and 14.85-cent operating cost figure.
Its footnote points to the very annual report containing the missing 15.79-cent total revenue figure. The note also cites Wendover for the airline market-capitalization comparison. It is not independent confirmation of that comparison.

A mistake does not become sound financial analysis because another publication repeats it.
The airlines' financial assets are also their creditors' collateral
Wendover describes loyalty programs as privately controlled central banks, with airlines enjoying almost complete control over the creation and value of their virtual currencies.
There is truth in the underlying observation. But the description leaves out an important complication: the loyalty businesses have substantial creditors, contractual restrictions and future obligations.
United's MileagePlus financing provides an unusually clear example.
The financing documents gave lenders first-priority security over program intellectual property, brands, member data, subsidiary equity and accounts receiving loyalty revenue. The final financing issued $6.8 billion in debt.
United's subsequent SEC filing explicitly warned that MileagePlus cash flows had to satisfy interest and principal payments first. The company said those funds would not be fully available for its operations during the seven-year financing term.
SEC+1
Delta's SkyMiles financing raised $9 billion through secured notes and a term loan.
Its financing agreements restricted material changes to program rules that could impair debt repayment, restricted sales of prepaid miles above $550 million in aggregate, and restricted changes to the intercompany agreements governing the program.
SEC+1
American subsequently raised $10 billion through its AAdvantage financing in 2021. The proceeds were lent to American after the establishment of reserve accounts, demonstrating how the loyalty business could be used to support the parent company's financing needs.
American Airlines
These businesses are powerful assets. But they are not unencumbered money-printing machines.
Their future cash flows are pledged to creditors, and their operating freedom is subject to financing agreements.
The money comes with promises attached
There is another accounting issue missing from the video's portrayal of loyalty revenue.
When airlines sell miles to commercial partners, they do not necessarily recognize the entire payment as immediate profit.
They allocate payments among different obligations. The portion associated with future award transportation is deferred until the miles are redeemed and the transportation is provided. Other benefits and marketing services have their own revenue-recognition arrangements.
This is documented in the airlines' own financial statements.
At December 31, 2025, the three major US carriers reported the following deferred loyalty revenue balances:
Airline Deferred loyalty revenue United $7.777 billion Delta $9.262 billion American $10.564 billion Combined $27.603 billionThese balances are not estimates of future losses or the direct cost of fulfilling every outstanding mile. They represent amounts deferred against future awards and other performance obligations.
SEC+2
The distinction is important.
An airline can receive cash from a bank today while still owing customers future transportation, upgrades, benefits or other rewards.
The business is attractive partly because airlines manage redemption rates, expected breakage and the cost of providing those benefits. But the obligations cannot simply be ignored when describing the program as nearly impossible to lose.
The video explains the airline's power to issue points. It does not adequately examine the balance sheet behind those points.
The real story is powerful enough without the exaggeration
Airlines have created extraordinary businesses from customer loyalty.
They sell access to their brands, customer databases, travel networks and reward systems. Banks pay billions to participate. Airlines can use those revenue streams and intellectual property as collateral to obtain enormous loans.
That is a remarkable transformation of the aviation business.
But Wendover goes further. It claims that the loyalty programs are worth more than the airlines and that the flight operations themselves have negative economic value.
The evidence presented does not establish that conclusion.
The valuations come from different methods and dates. The market-capitalization comparison ignores the distinction between equity and enterprise value. The American Airlines example compares passenger revenue against total operating costs, omitting other revenue. And the loyalty-program revenue figures are treated as though they were equivalent to profit.
There is a genuine financial revolution here. It does not require pretending that the arithmetic proves more than it does.
My verdict: Wendover has explained how airlines turned customer loyalty into a multibillion-dollar financial asset. It has not proved that the airlines themselves are worthless. Its most dramatic conclusion rests on a valuation comparison that is not like-for-like and a financial calculation that fails to count all the revenue. The distinction matters because a compelling explanation of an industry is not a substitute for an accurate account of its economics.
