Airplane Fare classWithin each travel class there are often different fare classes, relating to ticket or reservation restrictions and used to enhance opportunities for price discrimination. Passengers within the same travel class receive the same quality of accommodation and may indeed sit next to each other; however, the price or restrictions they face for that accommodation will vary depending on the fare class. Fare classes may also vary by how far ahead the ticket must be purchased, or how long the length of stay is.
For example, full fare economy class passengers (booking code Y) are usually able to make changes to their reservation, while discount economy class passengers in the lowest booking code usually have tickets that are non-refundable, non-upgradeable, non-transferable, or non-changeable without a hefty fee.
Airline fare classes are commonly indicated by letter codes, but the exact hierarchy and terms of these booking codes vary greatly from carrier to carrier. Hence, observe your flight tickets codes when booking...
First class codesA, F, P, R, Z
On domestic flights, F commonly indicates first class on a two-cabin plane. If a three-cabin aircraft is used, P (for "premium") may be used to distinguish the higher level of service in first class. The R code indicated supersonic transport and is no longer used with the retirement of the Concorde. The A and Z codes may indicate a first class ticket whose fare is reduced due to restrictions on refunds, advance reservation requirements, or other terms.
The codes in short:
A = First Class Discounted,
F = First Class,
P = First Class Premium,
R = Supersonic (Concorde),
Z = Business Class Discounted
(a lowercase "n" after any class code indicates Night Service)
Business class codes
C, J, D, I
On many airlines, C or J indicate full fare business class, whereas discounted and thus restricted and un-upgradeable fares are represented by D or I.
The codes in short:
C = Business Class,
D = Business Class Discounted,
J = Business Class Premium
(a lowercase "n" after any class code indicates Night Service)
Economy class codesFull fare: Y, B, H
Standard fare: M, N
Special or discount fares: G, I, K, L, O, Q, R, S, T, U, V, W, X
On most airlines, unrestricted economy ticket is booked as a Y fare. Full fare tickets with restrictions on travel dates, refunds, or advance reservations are commonly classed as B, H, or M, although some airlines may use S, W, or others.
Heavily discounted fares, commonly T or W, will not permit cabin upgrades, refunds, or reservation changes, may restrict frequent flyer programme eligibility, and/or impose other restrictions. Other fare codes such as X are restricted for use by consolidators, group charters, or travel industry professionals.
Most low-cost carriers have greatly simplified the fare classes they use to a handful of cases, unlike the dozens employed by a traditional airline. While some traditional carriers have followed, others continue to prefer price discrimination over commoditization.
The codes in short:
B = Economy/Coach Discounted
E = Shuttle Service (No reservation allowed), or Economy/Coach Discounted
G = Conditional Reservation
H = Economy/Coach Discounted
K = Economy/Coach Discounted
L = Economy/Coach Discounted
M = Economy/Coach Discounted
N = Economy/Coach Discounted
Q = Economy/Coach Discounted
R = Economy/Coach Heavily discounted
S = Economy/Coach
T = Economy/Coach Discounted, or Premium
U = Shuttle Service (No res. needed/Seat guaranteed)
V = Economy/Coach Discounted
W = Economy/Coach Discounted
Y = Economy/Coach
(a lowercase "n" after any class code indicates Night Service)
