The following is a description of the various seat codes by airline.
As a rule the seats codes become less expensive as you go down the list, however they also lose flexibility to change and have more restrictions on upgrades.
Note the highest number you will see for each code is 9, that means there are 9 or more seats in that code.
Also the numbers are not cummulative, so if you see J9 C8 D6 it doesn’t mean there are 23 seats available in BA club for example. There are at least 9 seats in code J, of which 8 are for sale as C and 6 as D.
Therefore it isn’t possible in all cases to give an exact number of seats until the numbers drop below 9 but you can see a trend with how the cheaper seat codes are selling as to how busy the flight is.
