Reservation Booking Designator (RBD)
Reservation Booking Designator (RBD)
Airfares are composed of fare and rule components that define the product, services, and pricing. These components include the origin/destination pair, fare class, one-way/round-trip indicator, fare amount, validity dates, mileage, and other specific rules. To manage and sell airfares, airlines use inventory allocations within finite, alphabetically-defined sub-groups known as "inventory buckets," each associated with specific fare codes. This method of defining and managing airfares through fare codes has been in use since the early days of commercial air travel, even before computerised reservation systems were introduced. With the advent of computerised systems in the 1960s, this approach was further refined and became widely adopted across the industry.
The booking class of a flight, such as F, D, J, I, Y, or M, is determined by its Reservation Booking Designator (RBD). The RBD code is used during the reservation process to identify the selected booking class, which corresponds to specific seating arrangements and cabin categories. Additionally, the RBD indicates the type of cabin or service class provided by the airline. For example, the code 'J' typically represents Business Class, though it may denote Economy Class on certain airlines.
Travel Class Overview
A travel class refers to the quality of accommodation on public transport, such as a seat or cabin. Higher travel classes offer greater comfort and are generally more expensive. Traditionally, airlines divide their cabins into First Class, Business Class, and Economy Class, arranged from the front to the rear of the aircraft. In recent years, many airlines have introduced a Premium Economy Class as an intermediate option between Economy and Business Class.
Common Booking Codes and Corresponding Classes:
• F: First Class
• J: Business Class
• W: Premium Economy
• Y: Economy Class
Randomised Block Design (RBD)
In experimental design, Randomised Block Design (RBD) is a method where subjects or experimental units are grouped into blocks, and different treatments are randomly assigned within each block. This approach simplifies data analysis and enhances clarity.
In the context of airlines, RBD is implemented to ensure business sustainability. Below are the typical fare codes used by airlines:
1. Full-Fare First Class : A, F
2. Full-Fare Business Class: J, C, D
3. Discounted Business Class: D, I, Z
4. Premium Economy Class: W, E
5. Full-Fare Economy Class: Y, B, M, H
6. Discounted Economy Class: K, L, Q, V, W, U, T, X, N, O, S
It is important to note that fare basis codes may vary depending on the airline.
This structured approach ensures efficient management of airfares and aligns with the operational and business strategies of airlines.
