4 Types of Classes on a Plane (Are There Clear Distinctions?)

While most of us find air travel helpful in traversing long distances, how many of us can explain its operations and features?

As a former pilot, I had to brush up on a plane’s intricacies, including the different classes within the cabin. In truth, the features are impressive and the history of their origins even more so, so here are the four types of classes on a plane:

  1. Economy Class
  2. Premium Economy Class
  3. Business Class
  4. First Class

Economy class has the least legroom, while Economy Premium has amenities and more legroom. Business class offers substantial amenities, and First Class goes far beyond amenities. 

The history of plane classes is pretty fascinating, with some offering amenities that rival five-star hotels.

Let’s explore each cabin section and consider what your money will afford you. I’ll also cover how these classes differ from years back, examining details like seat spacing and amenities to get the most authentic feel for the plane class. 

1. Economy Class

The economy class cabin goes by many names to distinguish it from premium economies, like coach class or standard class. It’s the lowest travel class of seating in air travel, making it the most inexpensive and with the least amount of amenities. 

Whatever you choose to name it, economy class is the most basic class. Nowadays, economy class is little more than a place to sit and go from point A to point B.

Seats are relatively small, ranging from 16 to 19 inches (40 to 48 cm) in width, with legroom typically ranging from 30 to 34 inches (76 to 86 cm).

However, carriers like JetBlue and Hawaiian Airlines give more perks than others, such as complimentary food, beverages, and in-flight entertainment systems.

Delta Air Lines offers three classes of service: Delta One, First Class, and Delta Comfort+. 

  • Delta One – while flying cross-country and internationally, you can enjoy features like a 180-degree flat-bed seat with Westin Heavenly bedding and even a dedicated flight attendant.  
  • First Class – provides up to 8 inches more legroom, a 5.4-inch seat recline, and a larger seat-back screen.
  • Main Cabin – there are three distinct experiences dependent on seat size and position. Delta Comfort+, Main Cabin, and Basic Economy are all options.

Allegiant Air, Frontier Airlines, and Spirit Airlines are low-cost airliners and offer only coach classes.

2. Premium Economy Class

Regarding pricing, comfort, and facilities, premium economy class, also known as economy plus, is usually between standard economy class and business class. EVA Air was the first airline to offer premium economy under the moniker Evergreen Class in 1991, becoming the first airline to do so.

Premium Economy class has become a standard depiction of what economy class was like several decades ago in many aspects. This class has evolved in several nations as a reaction to governments and businesses mandating economy class for their employees’ travel requirements.

Premium economy, formerly accessible only on overseas flights, is now available on domestic flights inside the United States. The somewhat more comfortable premium economy class offers larger seats and greater legroom at a lower cost than business or first class on most airlines.

Some airlines classify economy and premium economy as part of the main cabin class. It is often partitioned on international and certain long-haul flights to provide greater room and a convenient placement towards the front of the aircraft.

On foreign flights, the premium economy may not only be physically separated from economy class but also includes additional benefits such as complementary or improved cuisine, increased luggage allowance, and amenity kits. On domestic flights, premium economy frequently refers to the better seats on an aircraft.

3. Business Class

Business class is one of the more illustrious options available on many commercial airlines with various names depending on the carrier. The initial purpose of the airline industry was for business class to provide an intermediate level of service between economy and first class. A large number of airlines now offer business class as the quintessential level of service, having phased out first-class seating.

The quality of seats, meals, beverages, ground service, and other amenities distinguishes business class from other travel classes. Business class typically has a specific ticket letter association, represented by the ticket letters J or C, and provides scheduling flexibility. However, these letters are sometimes interchangeable, depending on the circumstances.

Following airline deregulation, airlines such as Pan Am and Qantas pioneered business class. When international first-class ticket prices rose, economy-class discounts became the norm, but full-fare coach passengers were displeased.

Business class is not the same as economy class, and airlines have improved the quality of this category to the point that some have replaced first class with business class, as was the case with the now-defunct Continental Airlines. When the airline BusinessFirst established itself in the early 1990s, it blended the benefits of business class with the luxury of first class.

International flights on some airlines, such as Delta Air Lines, may provide business class service instead of first class. On American Airlines, the experience includes a larger seat that reclines but does not lie flat, complete dinner service, in-flight entertainment, and an amenity kit.

Furthermore, Emirates airlines may have seats that convert to a lie-flat seat, a personal minibar, multi-course meals served on exquisite plates, and a bar area with a bartender and canapés.

4. First Class

On certain passenger planes, first class is a more opulent travel class than business class, premium economy, and economy class.

First class on a passenger airplane often refers to a restricted number of seats, and it exists nearer to the front of the aircraft to provide additional room, service, privacy, and comfort. Typically, first class is the highest class available, while some airlines have branded their new products as above first class or offered business class as the highest class available.

Propeller planes frequently had first class towards the back, away from the engine and propeller noise. First class aboard jet aircraft is usually towards the front of the airplane, often ahead of business class or on the top deck of wide-body aircraft like the Boeing 747 and Airbus A380. Furthermore, It is not possible to upgrade passengers beyond first class.

The experience of first-class can range from JetBlue’s Mint, which features outstanding amenities like:

  • 6-foot, 8-inch lie-flat seat, adjustable and comes with a massage feature.
  • a door for maintaining privacy
  • in-flight entertainment like movies or games
  • full meal service
  • 3-room suite with a living area
  • bedroom with a double bed 
  • beautiful private bathroom with a shower

Planes Have Fare Classes With Varying Rules And Prices 

Economy, premium economy, business, and first-class service classes have additional categories that separate them into fare classes, as shown by the letter on your ticket. Each seat on an airplane has a fare class with its own set of restrictions and costs. What appears to be a random letter on your ticket is a critical piece of information to consider!

You can expect one of the 26 letters of the English alphabet to indicate the fare class of your ticket, often known as a booking class or fare bucket. While the International Air Transport Organisation (IATA), an airline trade association, was the first to standardize booking codes, airlines now utilize their own.

Fare classes are a tool that airlines, reservation systems, and travel agencies use to keep track of tickets sold and fare class availability. The fare class letter indicates how much your ticket will cost, how many airline miles you will earn for the journey, and how much freedom you have to modify your reservation.

In fact, one single letter might mean spending hundreds of dollars more or less for your ticket than the individual next to you.

Each letter of the alphabet has a separate fare class on most flights; however, it varies per carrier. Regardless of the airline, the letter F represents first class, C and J represent business class, and Y represents economy.

The letters assigned to each fare class are not random occurrences. For instance,  the letter C for business class relates to Pan Am, one of the first airlines to launch Clipper Level, a new class of service for business and full-fare economy travelers.

Because airlines are companies, they want to earn the most money possible for each seat while simultaneously attempting to fill the aircraft. As a result, ticket prices fall into certain fare classes or buckets to assist limit inventory and tracking the number of tickets available at a given price.

Each fare class has its own set of prices and limitations, such as how much mileage is earnable through the airline’s loyalty program and if the ticket is flexible. Did you know there are secret fare classes for frequent flyer awards and elite upgrades that do not appear in travel searches?

How Do You Use Your Fare Knowledge To Buy Tickets?

By selecting the advanced booking options on most airline websites, you may search for flights by fare class. Expert Flyer, for example, allows customers to search for flights by fare code.

When browsing airline websites for tickets, the price code is displayed at the conclusion of the buying process, either when selecting flight choices or right before completing payment. Typically, there is a relationship between the fare class and the ticket price; the lowest tariff classes are the cheapest rates.

Tickets that have more perks and fewer restrictions have higher fare classes (and, most often, higher prices). Thus, if you’re looking for the best flight experience, it might be worthwhile to spend some time looking for tickets that offer the best combination of amenities and pricing. 

The Hub-And-Spoke System Started Airline Classes

Small airport runway

Did you know that all seats were first class? Airlines began experimenting with off-peak coach flights in the 1950s, i.e., not first class and coach cabins divided by a curtain but wholly separate flights. Later, as we see today, they began selling two cabins on the same aircraft.

Seats were broader because airlines were subsidized, allowing them to travel fewer people to more remote regions. It changed, however, with the advent of the hub-and-spoke routing scheme.

The hub and spoke model is a distribution strategy that includes a centralized hub. Everything begins at the hub or goes to the hub for consumer distribution. Goods get transported from the hub to smaller facilities controlled by the corporation, known as spokes, for further processing and distribution.

The airline industry revolutionized the hub-and-spoke concept. Airlines operate from a centralized hub, with outlying airports serving as spokes from which they offer flights. Aviation experts agree that the hub and spoke concept resulted in the airline sector rapidly expanding due to the effective utilization of relatively few air transit resources. 

Smaller rural airports, known as spokes, take passengers to bigger centralized hub airports. A connecting flight might then take them to another small airport. It works better than having many direct routes from one regional airport to another.

The downside of this arrangement is realized mainly by passengers, who may face delayed flights and additional transit time by taking two separate flights rather than one direct journey. Congestion at consolidated hub airports can also lead to passenger displeasure. 

Although many big airlines believe the benefits of the hub and spoke concept outweigh the drawbacks, some smaller airlines are taking advantage of the service gap.

Passenger numbers now determine destinations, which gave rise to the idea of how many seats an airplane can accommodate while keeping safety requirements. Some aircraft seats have diminished over time, while others have stayed consistent across all service levels.


Plane classes come with Economy, Economy Premium, Business, and First Class.

The economy has minimal legroom and usually has no amenities. Premium is similar but with more space and some extras, while Business and First class are the heavy-hitters with impressive amenities and legroom.

However, some airlines have replaced First Class with Business Class as their most luxurious option.
