Sounds like NZ's Premium Economy which is booking codes UEO.

You got it right. Now there's a couple more EC booking classes: E and U (E is considered full fare in some markets with LCC competition, U is notch below that). The hierarchy is as follows:

YBEMUHQVWSTKLG

the paid booking classes at TAP are:

BC: CDZ
EC: YBMHQVWLSKUN

Thanks. OP is updated. Have any of the BMI classes changed following the changes to their business model?

I don't know if it's new, but in long haul, BMI has K and G class, too.

Kiwiflyer,

TG has a U class, which is 110% status and redeemable miles. U is for their E+ product, which is sold as a 4th class on its 345 and 346 jets.

SQ,

As you know, G,V,Q,N,T (think should be ranked in this order) are no miles classes. I believe the ranking for the the Y tickets would be in this order , based on my limited knowledge.
Y,S - full fare economy. think its 1 yr tix
B - 4 mth tix. ?full fare
E - 1 mth tix. discounted, with miles

I have not seen a G ticket in use, but have heard of an M fare originating BKK. But it ranks higher than E.

Not sure about the other classes.

Why not mark booking classes that not accrue miles in bold so we can avoid them (W, K, L, G on SK) ?

Lots of info here: http://www.flyertalk.com/forum/showthread.php?t=352627

Unfortunately that could possibly vary by FFP even when the flight is operated by the same airline. However where it is universal that could be a useful enhancement.

I'd probably make them a smaller font size, rather than bolded.

U is for Premium Economy on TG A345. How about Z?

Hm, you got me there CGK. Not too sure? Maybe discounted Biz like UA?

Yes, the 345 has Premium Economy on the ultra long haul routes.
Nearly forgot, one of their AB6 SIN-BKK vv also sells U class. From what I've heard, Y+ on that plane is what they actually sell on the other 3 flights as J! Yes, the old J seats are being sold at Y+ :D I think its TG 414? I could be wrong with the flight number though.

Great resource!
 

Excellent resource! Thanks for all the information. Seems rather hard to find outside FT!

O-Class on SK Domestic in Norway
 

O-class is not an advertised class on SK, but it is apparently still used for Military Fares on Domestic Norwegian routes. I got an E-ticket today for my first trip for the Army since 2002. Fare Class is listed as O First. Of course, First class does not exist on DOM NO. SKBU are running a LCC operation when it comes to inflight service in any case, but in the SK database O apparently loads as First, not Economy.

When earning of miles/points still was possible on DOM NO Military O-class earned as business/full fare: 1200 EB points per segment.

SAS also use -E- for economy within Europe.

LH use also U for economy.


LX booking classes:

FC : FA
BC : CDZJ
EC : YBMHUGQKVLWPTE


SA booking classes:

FC : FA
BC : JCZ
EC : YMBKHSQTVLXG

To add to the last post, both LX and SA are using Star Standard classes for rewards/redemptions. O for First, I for Biz and X for Y cabin.
