Low cost carrier: definition, features, and examples

What is a low-cost carrier?

A low-cost carrier (LCC) is an airline that offers cheap fares by running a lean, cost-focused business model. These airlines exploded in popularity after aviation deregulation, and their core idea is simple: unbundle everything. Instead of paying for meals, checked bags, and other extras bundled into the ticket price, travelers pay only for what they actually want. That way, the savings get passed on directly.

Low-cost carrier vs ultra-low-cost carrier

Standard LCCs make travel affordable, but ultra-low-cost carriers (UL CCs) push cost-cutting much further. Where a typical LCC might still include a carry-on bag or let you pick a seat without extra charge, a LCC strips the ticket down to just the seat. Everything else costs extra, including airport-printed boarding passes and sometimes even drinking water onboard. UL CCs also run on the smallest possible crews and squeeze every bit of utilization out of their staff to keep base fares as low as they go.

How low-cost carriers keep fares low

Budget airlines use a range of operational strategies to cut costs and offer cheaper tickets. One of the biggest is fleet standardization: flying a single aircraft type slashes maintenance costs and simplifies pilot training. Airlines also negotiate bulk deals with manufacturers and fuel suppliers to benefit from economies of scale. To avoid paying commissions to third-party booking platforms, most budget carriers push customers to book directly through their own websites. On top of that, dynamic pricing algorithms adjust fares in real time based on demand, which helps maximize revenue per flight while keeping entry-level prices competitive.

Why ancillary revenue matters

Ancillary revenue covers everything an airline earns beyond the base ticket: baggage fees, seat selection, onboard food, and partnerships with third-party companies. These add-ons provide real financial stability, letting airlines stay profitable without raising ticket prices. Revenue management teams handle the pricing of these extras to push non-ticket earnings as high as possible. Without this income stream, heavily discounted promotional fares simply wouldn’t be sustainable.

Why low-cost carriers use secondary airports

Budget airlines frequently choose secondary airports over major international hubs, and the reason is straightforward: lower costs. Smaller, less congested airports outside city centers charge far less in landing and gate fees. Legacy carriers tend to prefer central airports for their premium facilities, but discount operators have no interest in paying for terminals they don’t need. There’s another benefit too: less air traffic means planes spend less time waiting on the tarmac, turnarounds are faster, and those savings eventually reach the passenger.

How low-cost carrier networks are built

Legacy airlines route passengers through central hub cities using a hub-and-spoke system. Budget carriers do the opposite, building point-to-point networks that connect high-demand destinations directly. This cuts out complex baggage transfers and prevents delays from cascading across the whole network. Fast turnarounds are central to this model, keeping aircraft flying and earning rather than sitting idle at the gate. Filling seats on direct routes is how discount carriers keep their operations efficient.

How big is the low-cost carrier market?

Budget aviation has grown into a substantial global industry. In 2015, these airlines carried 984 million passengers, which was 28 percent of all scheduled passengers worldwide at the time.

Looking ahead, the global low-cost sector is projected to reach 430.5 billion US dollars by 2033. South Asia and India currently show the highest rates of budget travel adoption. Continued growth is being driven largely by smaller, previously underserved markets that budget carriers are now reaching for the first time.

Examples of low-cost carriers

Across different continents, a handful of carriers have come to define what budget travel looks like. In North America, Southwest Airlines, Spirit Airlines, and Frontier Airlines are the main players. In Europe, Ryanair, easyJet, and Wizz Air popularized the no-frills model and brought unbundling into the mainstream. Across the Asia-Pacific region, AirAsia, Jetstar, and IndiGo are the go-to options for affordable travel. In the Middle East and Africa, Dubai and Air Arabia are among the growing budget brands. All of them rely on point-to-point routes to stay competitive in their respective markets.

What changes when legacy airlines copy LCCs?

To survive in a price-sensitive market, traditional airlines are increasingly borrowing from the budget playbook. Many now offer basic economy fares that remove perks once considered standard, like free checked bags and advance seat selection. The line between full-service and discount carriers is blurring as a result. With budget operators set to receive large numbers of new aircraft in the coming years, they will push further into routes that legacy airlines have long dominated. That pressure is forcing legacy carriers to cut their own costs just to stay relevant.

What does ASK measure in aviation?

Available seat kilometers measure an airline’s total passenger-carrying capacity. The calculation is simple: multiply the number of seats on a flight by the distance flown. Analysts use this figure to calculate key efficiency metrics, particularly cost per available seat kilometer (CASK) and revenue per available seat kilometer (RASK). Dividing total costs or revenue by total capacity gives airlines a clear picture of their financial performance. For budget carriers operating on thin margins, keeping a close eye on these numbers is essential.
