Great info, Patron. Thank you!
One comment. I just booked LOT Polish business class award using United miles and my ticket shows booking class I, not Z.

Adding to the list of thanks! ^

Adding to the list of booking classes: "S" class for bookings on Executive Economy (SIN-EWR and SIN-LAX nonstops) for SQ

Great list, but what about cathay pacific? :)

Great Thread
 

I vote for it being made a sticky too ^

Would it be possible to add the US codes to the list as well, as they're officially joining on May 4th?

Another vote for sticky

Thanks--another reason I love FT! ^

Vielen Dank Patron!
Eine wunderbare Übersicht. Man könnte noch die ganzen Kombi-Tarife z.B. bei Lufthansa ergänzen ;-)
LH Y* G K L T (Y* nicht zu verwechseln mit dem regulären Y!)

English: (not so good!)
Thanks Patron!
a great view. There a some spezial LH Bookingsclasses.

Same here with LH. I did an upgrade for me and an award ticket for Frau D. Both showed up as I.

LOT realigned their booking class recently. (The codes for LOT in Patron's original post are LOT's original booking codes)

So award business class on LO will be I and X for economy class. (No First class).

Greay post, it helped understand me one of my current issued flight tickets with ANA ;) ^ :)

I believe Spanair has Z as their discount business-class.

Enhancement
 

Hi,

Thanks for the great compilation.

Will be a bonus if we can highlight the booking classes which *A members will not be able to earn/accrue mileage points (e.g. on SIA - "Q" class)

Great work though!

Nice idea, but would make for a messy table as they can vary by FFP which is being credited (or not in this case if you get what I mean!). Perhaps highlight only those which dont earn mileage for any *A FFP?

Here's the US codes for you:

F A - first (domestic only) E/O/P used for upgraders/awards
C D Z - business (international) I/R used for upgraders/awards
GHKLMNQSTUVWXY - coach

Thanks mikelaw

Can you (or someone) please rank the codes from full fare to most heavily discounted within the classes?

Cheers
