The cheapest class on a flight is typically Economy Class (sometimes referred to as Coach). Within Economy Class, airlines often offer various fare categories that can vary in price based on factors like booking time, flexibility, and additional services. Here's an overview of how the different classes compare:

1. Economy Class (Standard/Basic)

• Description: This is the most affordable class and is the default class for most passengers. It typically offers basic amenities, such as a seat, in-flight entertainment, and limited food and beverage options, depending on the airline and flight length.

• Price Range: Economy class tickets can range from budget (if you book in advance or find deals) to higher economy fares (if you're booking closer to the departure date or need flexibility).

• Flexibility: There are often different fare types within Economy Class, such as Basic Economy, Standard Economy, and Flexible Economy, with Basic Economy being the most restrictive and cheapest, offering minimal flexibility (e.g., no changes, no seat selection, etc.).

2. Basic Economy (Subcategory of Economy)

• Description: Basic Economy is often the cheapest option within Economy Class. It comes with more restrictions, such as no seat selection, limited baggage allowance, and no changes to the flight. This fare is often used by budget airlines or as a low-cost option by major airlines.

• Price Range: This is the cheapest fare, but it can also come with more limitations and fewer perks.

Comparison with Other Classes:

• Premium Economy: More expensive than standard Economy, offering more legroom, better seats, and upgraded amenities.

• Business Class: Offers more comfort, premium service, and amenities, typically at a significantly higher price.

• First Class: The most luxurious and expensive class, with highly personalized service, better meals, and extensive amenities.

Key Tip:

If you're looking for the cheapest possible fare, booking in Basic Economy (if available) or standard Economy class well in advance, avoiding peak travel dates, and using fare comparison tools can help you find the best deals. Keep in mind that with cheaper fares, you might face additional fees for things like checked baggage or seat selection.
