Travel and Airlines: Booking, Marriott, Buffett, and Why Airlines Destroy Investors

2016. Warren Buffett bought shares in Delta Air Lines, United Airlines, Southwest Airlines, and American Airlines for approximately $10 billion. Commentators were shocked — Buffett, who for decades had called airlines an investment trap, had returned to them. 2020: Buffett sold everything at a large loss and admitted it was a mistake. What happened, and what does it teach us about investing in the travel sector?

Why Airlines Are a Different Business from Tourism

Tourism is a vast sector, but it encompasses entirely different business models. Booking Holdings or Airbnb earn on intermediation — they take a commission, own nothing, have no planes, hotels, or staff in the thousands. Marriott is a middle ground — it owns some hotels, but primarily franchises its brand.

Airlines are fundamentally different: enormous debt for aircraft, fuel costs accounting for 20–30% of revenues, powerful unions with contracts that cannot be quickly restructured, and the need to maintain a dense network of routes even when some are unprofitable. The result is a business with thin margins that is extremely sensitive to external shocks — pandemics, terrorist attacks, oil crises.

Booking Holdings: Asset-Light Tourism in Its Purest Form

Booking Holdings (BKNG) is the parent company of Booking.com, Priceline, Kayak, and others. The model is simple: a customer books through the platform, the platform takes a 10–15% commission, and the hotel or landlord receives the rest. Booking owns no hotel. Over 800,000 accommodations — without a single employee doing housekeeping.

This is the definition of asset-light. Capital expenditures are minimal — it's primarily IT and marketing. In a recession, the drop in demand hurts, but the firm quickly cuts marketing spending and has no fixed costs for hotels or aircraft. The result: even after a dramatic collapse during COVID, Booking returned to profitability faster than airlines.

Marriott: The Franchise as an Advantage

Marriott International (MAR) operates over 8,000 hotels under 30 brands — from Ritz-Carlton to Four Points. A key part of the business is franchise: hotel owners pay Marriott a licensing fee for the brand, reservations system, and loyalty program. Marriott mostly doesn't own hotels — it operates or franchises them.

This distinguishes Marriott from the traditional hotel business. Capex is lower, margins are more consistent. In a recession, guest numbers fall, but Marriott still collects franchise fees, albeit lower ones. The Marriott Bonvoy loyalty program with over 200 million members is a valuable business in itself — generating data and loyalty.

Why Airlines Decimate Investors: The Numbers and Mechanism

Since 1978 (deregulation of the American aviation market) through 2020, over 200 American airlines went bankrupt or entered bankruptcy proceedings. Shareholders in each bankruptcy typically lost their entire investment. Bondholders recovered a portion. Management left with golden parachutes.

Why? The aviation industry has a commodity-priced market (customers compare prices, loyalty is weak), extremely high fixed costs (aircraft leasing, hangars, personnel), and cyclicality dependent on the economy, security, and pandemics. Margins are so thin that a single shock is enough to trigger a liquidity crisis.

• Southwest Airlines: the best-managed American airline, consistently profitable — yet even it experienced turbulence during COVID
• Delta Air Lines: one of the better players thanks to its premium segment and cargo division
• Ryanair in Europe: a low-cost model with disciplined costs — an exception in the European context

JETS ETF: A Tactical Bet, Not a Passive Investment

The U.S. Global Jets ETF (JETS) tracks American airlines and aviation leasing companies. After COVID, JETS was a popular tool for betting on airline recovery — and in 2021 it worked. As a long-term passive investment it is unsuitable: the sector structurally underperforms the market.

Tourism as a whole — including Booking, Airbnb, Marriott, and cruise lines — is a more interesting investment story than airlines alone. Those seeking exposure to travel recovery are better off looking at platforms and hotel franchises rather than carriers themselves. This is not investment advice.

Airbnb and the Platform Economy in Tourism

Airbnb (ABNB) is the purest example of the platform economy in tourism: it owns zero properties, employs minimal hosts, and yet intermediates hundreds of millions of nights annually. Margins are significantly higher than for hotels and the business is scalable without capital investment in real estate.

Cruise Lines: A Niche Business With Loyal Customers and Enormous Debt

Cruises are curious investment subjects. Customers are above-average in loyalty — many travel by cruise repeatedly every year. Revenue per passenger is predictable thanks to the all-inclusive model. Carnival, Royal Caribbean, and Norwegian are the three dominant players.

The problem is COVID-inherited debt: ships couldn't sail, but companies had to pay leasing, staff, and port fees. Firms survived through massive equity and bond issuance that diluted existing shareholders. The business returned to profit — but the debt burden and historically low margins make cruise lines a risky choice for conservative investors. For more speculative players they are interesting precisely because of the high financial leverage: when results are good, the stock flies; when disappointing, it falls.

How to Think Correctly About Recovery Investments in Tourism

After every crisis, tourism attracts attention as a "recovery play" — you buy a cheap company at the moment the business is temporarily suffering, and wait for normalization. This logic can work, but requires certainty that the problem is transient, not structural.

COVID was transient — the business came back. But airlines returned with problems of debt, fuel costs, and labor disputes. Structural problems persisted. Booking Holdings and Marriott returned stronger and with better structure. This distinction — transient vs. structural crisis — is critical for any recovery investment. Without it, it's more speculation than analysis. More on stock and sector selection in the company analysis section.
