Is there a link where all codes are explained?

I have searched here and Google but nothing really good info. Maybe I just didn't search properly...

Every single one or just the generics?
F = First Class
J = Business Class
Y = Economy

Specifically for Air Canada, http://www.aircanada.com/en/aeroplan...milesChart.pdf is a handy chart that lists all of the booking codes, with mileage accumulation details.

All the codes are described in the Air Canada Miles Earning Chart. Note that some codes vary depending on the destination, W is Flex for flights within Canada and Tango for international flights.

There are also additional codes for reward tickets (X and I) and upgraded fares (R).

Thanks for the links above but I saw that and its in the FAQ too but they are only showing the codes for Business Class, Flex and Tango in general and it shows what "letter" they are.

But ya something like X and I are reward tickets and R is upgraded but how about the rest?

I know the generic, but wondering more every single ones. Especially Flex where it has lots of different classes. It may or may not be important for most but I guess its good to know.

Some of them are for Flight Passes, Earn points, No points, Upgradable, Rewards, etc...

I'm not sure I fully understand what you are asking for here.

For revenue tickets, it follows the chart. For instance, domestic flights have the following booking class:
Latitude (Y,B)
Flex (M,U,H,Q,V,W,G)
Tango (S,T,L,A,K) (N,E)

For Flight Passes, they will typically book within the the highest booking class within the purchased fare. For example, a Flex flight pass will book in M.

For Unlimited Flight Passes, not sure which fare bucket they book into but they are not eligible for miles or AQS.

Upgraded fares (R booking class), either Last Minute Upgrade or eUpgrades, you will receive miles according to the original purchased fare.

Award Tickets will be X for Economy and I for Business class.

So pretty much this....

Latitude (Y,B) What does Y and B mean? Whats the difference
Flex (M,U,H,Q,V,W,G) What do each of this letter/classes mean.
Tango (S,T,L,A,K) (N,E)

I'm buying an Economy FP soon, I saw a thread where its V and now could be M

Each of the codes don't have a "meaning", per say, other than their precedence in the codes and certain restrictions for their purchase. In other words, the higher the code (M is higher than H, which is higher than W) the higher the fare normally is.

For Flex, for example, the airline could start selling cheap V fares as far as 6 months out... but with a time limit. The V fares could only be valid until they are sold out or 30 days before a flight, at which time that fare will fully disappear. As one fare bucket sells out or expires (e.g. G) then only tickets at the next class up and above can be sold.

As well, when it comes down to upgrades et. all, the higher the code is the higher in the priority listing you are, for your Altitude status level. So an E50K with an M fare would be upgraded before an E50K with a W fare.

The breakdown of each Flex code (which in reality are Y economy tickets with pre-set fare conditions and discounts) have the above restrictions and discounts.

Either way you would earn 100% of your AQM's from the flight pass, however with an M fare you would now be above all of the other Flex fares when it comes to upgrades. With the usual restrictions for upgrade priority in place, that is.

Edit: Here's an example of AC810 for tomorrow, showing the fare codes as of this minute: J7 C7 D5 Z2 P0 Y9 B9 M6 U6 H6 Q2 V0 W0 S0 T0 L0 K0 R0
As you can see there are no Tango fares left, and the lowest Flex fare would be a Q. If your flight pass only allowed for V fares to be booked, you would not be able to book that flight... while there are still 6 M seats left.

The different letters indicate broadly different prices and different rules. For example, an M fare has fewer restrictions than most other Flex fares (e.g., around requiring a Saturday overnight on international long haul flights).

Would this help?

Thanks for the explanation folks! some of those classes usually confuses me aside from the generic classes.

The letter doesn't define the advance purchase requirement. There could be different V fares with 3, 7, 14 & 21 day a/p rules.

Revenue management will control how many seats are in each bucket, in addition to what fares are published and what the associated rules are. But the letters in and of themselves don't have meaning other than to define the buckets from which the inventory is sold.

To buy a seat on a flight there must be a published fare, inventory in that fare bucket and you must meet all the rules of the fare.
