Are Airlines Redefining "Premium" to Boost Ancillary Fee Revenue?

The commercial aviation industry is seeing record profits.

Delta Air Lines and United Airlines recently reported strong financial results.

Delta Air Lines posted a $5.0 billion pre-tax profit for 2025.

This success is largely attributed to a growing demand for premium products.

Delta's premium revenue grew 7% year-over-year in 2025.

However, the definition of "premium" is changing dramatically.

Many services once included in a standard fare are now costly add-ons.

These include seat selection, checked bags, and early boarding.

For many passengers, these "upgrades" simply restore basic comfort.

The Rise of Ancillary Fee Revenue

This shift is driven by the industry's focus on ancillary fee revenue.

Ancillary revenue includes all non-ticket purchases.

Globally, this revenue stream is soaring.

IdeaWorksCompany projects a record $157 billion in global ancillary revenue for 2025.

This is a massive increase from $67.4 billion in 2016.

Ancillary services now account for nearly 14% of total airline revenue.

This is up from 12-13% before the global pandemic.

Legacy carriers initially used unbundling to compete with discount airlines.

Now, it is an integral part of their business model.

Unbundling as Price Discrimination

Airline pricing is a classic case study in microeconomics.

Experts note that airlines are masters of market segmentation.

They use unbundling to practice a form of legal price discrimination.

This means consumers self-select into different price tiers.

Those who prioritize a window seat or legroom pay more.

Those who prioritize the lowest cost accept a basic economy fare.

This strategy allows airlines to capture more revenue from every traveler.

It works even if the base airfare is lower than decades ago.

This is true when adjusted for inflation, according to experts.

The Consumer Experience Paradox

Despite the profits, customer frustration remains high.

Paying extra for basic elements feels like a mild fraud.

There is little incentive for carriers to improve the main cabin experience.

If travelers pay more to avoid the worst seats, the strategy succeeds.

For example, seat pitch compression continues on many aircraft.

This makes the standard economy experience less comfortable.

This discomfort encourages more people to buy a "premium" seat.

It is a cycle that drives airline revenue growth at the expense of comfort.

Operational Benefits and Risks

Unbundling also offers operational advantages for airlines.

Charging for checked bags reduced the number of checked items.

This unexpectedly improved on-time departure performance.

It also lowered labor costs for baggage handling.

However, the strategy carries a significant risk to brand loyalty.

Consumer anger over fees can lead to avoidance behavior.

Carriers must balance revenue gains with customer satisfaction.

Delta Air Lines, for instance, highlights its on-time performance.

This is an effort to maintain a strong brand image.

Ultimately, the legacy carrier pricing model has changed permanently.

It is now about selling a base transport ticket.

Everything else is an optional, high-margin, airline premium product.
