Understanding Expert Flyer

[Danger]

I'd appreciate some help understanding the information EF provides. For example,

F6 A6 J9 C9 D9 I0 B9 H9 K9 M9 R9 L9 V9 S0 N0 Q0 O0 X0 E0

What letters do I look at to try to work out how many seats are still available in economy?

What letters do I look at to try to work out how many upgrade seats are still available (from discount economy to business)?

When doing a flight availability search, the "Class Code" fine print says

For a list of all Award and Upgrade codes we support or to search for a specific code, click here.

An example of clicking this link and entering QF as the Airline Code returns:

A QF FIRST
B QF ECONOMY
C QF BUSINESS
D QF BUSINESS
E QF SHUTTLE SERVICE
F QF FIRST
H QF ECONOMY
I QF DISCOUNT BUSINESS
J QF BUSINESS
K QF ECONOMY
L QF ECONOMY
M QF ECONOMY
N QF ECONOMY
O QF ECONOMY
P QF FIRST
Q QF ECONOMY
R QF ECONOMY
S QF STANDARD
T QF ECONOMY
U QF Business - Award
V QF ECONOMY
W QF ECONOMY
X QF Economy - Award
Y QF ECONOMY
Z QF First - Award


Perhaps someone else can further elaborate on if any of these can be interpreted as "upgrade classes".

It's more than expert flyer, this is how the Majority of airlines show fare availability for a flight.

The Alphabetic characters represent "fare bucket" codes and the numbers adjacent to each represent the minimum number of seats in that fare bucket an airline is prepared to sell for a particular flight at the time of query.

Now with the numbers, in order to keep competitors somewhat in the dark as to how many seats are actually available, the airlines have their own determined maximum number to reveal at any one time.

For QF it's generally 9, for AA it's 7 and for JQ, 4.

As a general rule of thumb, the letters indicate availability in a descending notional value order from left to right.

F6 A6: Qantas are willing to sell up to 6 seats in the Fist Class cabin. This at either the full rate (F) or discounted (A). This does not mean that there are 12 seats available. Note that currently, Qantas First class cabins have 14 'seats'. What would normally happen if someone booked on the flight into one of these code is that both numbers would reduce, i.e. it goes to F5 A5.

J9 C9 D9 I0: Business class seat and at least nine are up for sale at the Full (J) rate, Discounted (C), more discounted (D) rates. None at the deep discount rate (I).

B9 H9 K9 M9 R9 L9 V9 S0 N0 Q0 O0 X0 E0: These are the WHY rates and there are probably plenty of seats for sale, but none at deep discount (N, Q, O) and no award seats (X).

(Due to the numbers posted I would hazard a guess that this flight would be imminent, possibly within the next week)

... What letters do I look at to try to work out how many upgrade seats are still available (from discount economy to business)?

Unfortunately, since the middle of January, Qantas have stopped making such classes available for viewing. These are Z for First and U for Business. (also T for WP/CL/SG whY awards)

The only way at the moment is to do a dummy award booking online.

This is no longer the case, E/F now does show P, U, Z and X availability being award First, Business, Prem. Economy and Economy classes.

Only within a class of service, and only if considering point to point fares from a single market. There are many, many cases where the fares are in different order - some of which are of great interest to AFFers

There are at least 9 seats available in economy, but none at the very cheapest fares. Given reasonably discounted booking classes show availability at 9 it looks a fairly empty flight at this stage.

Care is needed in interpreting the booking class availability as there are wide differences in how bookings go for routes and even particular flights on the same route.

Some may be oversold by lots, if the airline expects a lot of no shows or is willing to operationally upgrade (op-up) passengers. Obviously to op-up the next highest class of service needs room, and maybe even first class if they need to move some pax out of business to make room for op-ups from economy. Different routes/flights/dates will affect how willing the airline is to oversell (and by how many). Each airline will base its own experience for the specific flight to determine the optimum number.

Even without oversold situations there is care needed in interpreting due to the arcane ways of revenue or yield management. For example availability in a certain booking class may be restricted to certain fares (eg allow round trip discounted business but no more RTW business - both of which use the same booking class), to certain markets (eg allow sales ex-Oz for SYD-LAX but not ex-US), to through fares (eg allow SYD-SIN if it is part of SYD-LHR) or excluding through fares (eg allow SYD-SIN only if SIN is the destination). Etc.

Airlines may remove availability even without a sale, or add more availability, if their view on what level of fares they can get for the remaining seats changes.

It takes practice to see how airlines handle these and observe the effect on the booking class availability, and what it means in terms of being able to buy seats, how many and when, upgrade chances (either paid for or op-up), award availability, chances of getting spare seats beside you, etc.

Aren't these the award seats available - Z (First) and U (Business) ? The OP is asking about how many upgrade seats are available, which I did not think you could decipher from this information.

Domestic upgrades from WHY to Business book into U class; the same category as for business reward seats.

This used to be the case for International upgrades as well, with the addition that upgrades from Business class to First class booked into Z class; the same category as for First Class reward seats. This changed on 25th May 2005 and now for international upgrades Qantas Yield Management make their decision approx. 24 hours before a international flight as to whether any upgrades are to be made available.

There is some conjecture that Z & U become available for these international flights for the purposes of any possible upgrading, but within the 24 black out for award bookings/upgrade requests so can't be accessed by QFFers.

My international upgrades from business ot first class have been booked into P class, not Z.

Would that mean that within 24 hours of my flight I can check whata avilability there is to get an indication of availability of UG that I had previously requested (obviously I wont know how far down the line I am)?
