Wonderful compilation!

For SK you can add S between Y and M. Personally I have never seen O on SK. Nice job.

^ ^ ^ excellent

Also L can be added to the end of the list. These are deeply discounted promotional fares!

Thanks. Actually saved me a call tonight to ANA.

Thanks Patron ^ ^ ^

With Lufthansa you left K,L,T and G out in Eco and Z is Business only AFAIK.
R.N and E is employee travel.

Thanks! ^

I opened this thread on continuous special requests from some fellow flyertalker within the last half year.

I see the strength in this compilation to know about the quality of a specific booking class, especially for mileage/voucher redemption purposes. The weakness, that this list is already outdated. My source is the latest printed addition of the *A product & service guide I have access to (unfortunately - as peter42 pointed out - there are typing errors). If I gain access to an updated edition, I will edit the opener, but as the system is so volatile and there are individual exceptions all the time, I stick to this product.

IMO for individual needs on specific flights the best source available for the general public I know is this availability tool.

Many thanks for this...you've saved me a lot of time on my upcoming beach holiday!

Gracias Patron... ^

Thank you, it looks great!

I think this should be made a sticky thread

Danke Patron.
