How Airlines
Make Money Beyond Tickets

✍️ Dr. Elena Marchetti 📅 June 20, 2026 ⏱ 16 min read Revenue Streams Ancillary Income

When you buy a plane ticket, you’re paying for more than just your seat. But for airlines, that ticket is often just the opening act of a much larger revenue story. In fact, for many carriers, the profit from a flight comes not from the seat itself — but from everything else you buy along the way.

The global airline industry generated $890 billion in revenue in 2025. While passenger tickets accounted for the lion’s share, non-ticket revenue streams — from baggage fees to credit card partnerships to cargo — are increasingly critical to airline profitability. In fact, the most profitable airlines are often the ones that have mastered the art of ancillary revenue.

📈 The Ancillary Revenue Revolution

Ancillary revenue — income from products and services beyond the ticket — has grown from a niche concept to a $100+ billion industry. According to IATA, ancillary revenue accounted for 14% of total airline revenue in 2025, up from just 4% a decade ago.

✈️ The A La Carte Model: The LCC Blueprint

The true pioneers of ancillary revenue were low-cost carriers like Ryanair, Southwest, and EasyJet. They recognized early that unbundling the travel experience could generate significant revenue while keeping base fares low to attract customers.

Today, every airline — even the most premium legacy carriers — has adopted some form of unbundling. Here’s how they do it:

🧳 Baggage Fees: The $28 Billion Cash Cow

Baggage fees are the single largest ancillary revenue stream for most airlines. In 2025, U.S. airlines alone collected $6.8 billion from baggage fees, up from $4.5 billion in 2018. Globally, the figure exceeds $28 billion.

The strategy is simple: offer a low base fare to attract price-sensitive travelers, then charge premium prices for everything else. On Spirit and Frontier, bag fees often exceed the ticket price itself, making the true cost of flying far higher than the advertised fare.

💳 The Credit Card Goldmine

One of the most profitable and least understood revenue streams for airlines is their co-branded credit card partnerships. Airlines don’t just earn money from loyalty program sales — they earn billions from partnering with banks to issue credit cards.

Here’s how it works:

• Affiliate Commissions: Banks pay airlines $100–$400 per approved cardholder in affiliate commissions.
• Revenue Sharing: Airlines receive a percentage of all purchases made on co-branded cards (typically 0.5–2% of transaction value).
• Mileage Sales: Airlines sell frequent flyer miles to banks, which are then used as credit card rewards. This is a high-margin revenue stream because miles cost almost nothing for airlines to create.

For some airlines, credit card partnerships are more profitable than flying itself. In 2025, Delta Air Lines earned over $7 billion from its partnership with American Express — representing more than 40% of its total operating profit. The company essentially has two businesses: flying airplanes and selling credit cards.

🏆 Loyalty Programs: The Hidden Asset

Frequent flyer programs (FFPs) are among the most valuable assets an airline owns. In fact, the value of an airline’s loyalty program is often greater than the airline itself.

• United MileagePlus was valued at over $10 billion in 2024 — more than the airline’s market capitalization at that time.
• Delta SkyMiles has been used as collateral for billions in loans because it’s such a valuable asset.
• American AAdvantage has a similar valuation, often exceeding $10 billion.

Airlines make money from loyalty programs in four ways:

1. Selling miles to partners (credit cards, hotels, rental cars).
2. Affiliate commissions from partner bookings.
3. Credit card revenue sharing (as discussed above).
4. Direct consumer spending on mileage purchases.

📦 Cargo: The Silent Profit Center

Most passenger flights carry cargo in their bellies — and cargo revenue is a significant and often overlooked profit center. In 2025, global air cargo revenue reached $175 billion, with passenger airlines accounting for a substantial portion.

For many airlines, cargo can turn a marginal passenger flight into a profitable one. A flight that’s only half-full with passengers might still be highly profitable if its cargo holds are full. This is a key reason why airlines operate flights even with light passenger loads.

🛍️ Onboard Sales and In-Flight Shopping

While the margins are smaller than baggage fees or credit cards, onboard sales — food, beverages, duty-free items, Wi-Fi, and entertainment — contribute significantly to airline profits.

• Onboard Food & Beverage: Global revenue of ~$10 billion. Airlines like Delta and United have premium food and beverage options that generate significant revenue.
• Duty-Free Shopping: Particularly popular on long-haul flights. Some airlines generate over $100 million annually from duty-free sales alone.
• Wi-Fi and In-Flight Entertainment: A growing revenue stream, with airlines charging $8–$30 per flight for Wi-Fi access.
• Ancillary Product Sales: Some airlines sell travel insurance, rental cars, and hotel bookings on their websites, earning affiliate commissions.

🏦 The “TravelBank” Model – Prepaid Travel Funds

Some airlines have introduced prepaid travel funds programs — essentially interest-free loans from passengers to the airline. Passengers deposit money into a “TravelBank” account, which they can use for future flights. The airline earns interest and investment income on those funds in the meantime.

United’s TravelBank is a leading example. Passengers can deposit funds and earn bonuses, while United uses the cash for operational needs. It’s a win-win: passengers get a discount on future travel, and the airline gets a cost-free source of capital.

🔮 The Future: AI and Personalized Ancillary Revenue

The future of non-ticket revenue is personalization. Airlines are using AI to analyze passenger data and offer tailored ancillary products to each traveler.

• Dynamic Pricing: AI calculates the optimal price for each ancillary product based on the passenger’s willingness to pay.
• Personalized Offers: If you’re a business traveler, you might see offers for lounge access and priority boarding. If you’re a family, you might see offers for extra legroom and in-flight meals.
• Behavioral Targeting: Airlines track your browsing and purchase history to offer relevant ancillaries at the right time.
• Real-Time A/B Testing: Some airlines test different ancillary offers on different passenger segments in real time to optimize conversion.

🧭 What This Means for Travelers

Understanding how airlines make money beyond tickets gives you a strategic advantage:

1. Compare Total Cost: The base fare is just the start. Always factor in baggage fees, seat selection, and other ancillaries when comparing airlines.
2. Optimize Your Credit Card: Choose a credit card that offers travel rewards that align with your flying habits. Co-branded airline cards can offer significant value if you fly frequently.
3. Pack Light: Avoid checked baggage fees by traveling with carry-on only. Many airlines now charge for carry-on bags as well, so read the fine print.
4. Pre-Order Meals: Some airlines offer discounts for pre-ordering meals online before the flight.
5. Book Through Aggregators: Use FlightInsight to compare total costs across airlines, including ancillaries.

⚖️ The Ethics of Ancillary Revenue

The rise of ancillary revenue has sparked debates about transparency and fairness. Critics argue that airlines are deceptive by advertising low base fares while hiding the true cost of flying. Supporters argue that unbundling gives passengers choice — they only pay for what they actually use.

Regulators are taking note. In the U.S., the Department of Transportation has proposed rules that would require airlines to disclose all fees upfront, including baggage, seat selection, and change fees. The goal is to ensure that passengers see the true cost of their flight before they book.
