C Class or D class
 

I've just received an itinerary back which shows travel to Europe as C class and travel back as D class. I tried to search the QF site to find out what the difference is and if it matters but I can't see anything.

Can anyone here enlighten me please?

I'm sure there are others on this forum more qualified to answer this, but my understanding is that they are both Business booking codes. 'C' is full fare bucket, whereas 'D' is a discounted bucket. RTW itineraries are typically booked into D class, such as DONE4 etc.

As far as onboard service and the earning of miles, there should be no difference. You're still in Business class both ways.

The previous answer is spot on, the service is the same for D or C but D is discounted business, so costs less than C. Some flights have only C available (D is zeroed out on high-demand flights).

Class order for business class is as follows:

J > C > D > I

J is the most expensive and flexible through to I which is the most heavily discounted and least flexible.

In current usage J and C seem to have become equivalent. Historically C was the standard full fare flexible business class, and J was 10% higher fare for a "premium" product when various airlines introduced first-generation improved business seats (pre-beds). Now some airlines use C, some use J. Cannot remember any airline that uses both J and C; and they seem to be completely equivalent on most airlines. D is usually discounted and refundable/changeable (with a fee) while I is a greater discount but non-refundable and often allowing no changes (not even date!).

Air Canada uses both J and C. J is full fare business, C is discounted.

Plus of course 'U' which is Award Business Class

D is more restrictive in availability (seats on flights and only available on certain dates). C is less restrictive (and more expensive).

I think the OP might have hit "post" twice, making this a duplicate thread to that 3 lines below!
(Paging Willyroo.... please contact the moderators desk regarding your upgrade and thread merger....) :)

Thanks for all responses [on both threads!].

QF - from personal experience (SYD-LHR-SYD).

and its identical twin brother ( well identical on the JSA run), BA

Dave

Given that QF and BA are JSA twins, how do they address the WT+ issue given QF are don't seem moved to make that innovation. Is the JSA revenue bulked and split or is it class dependent?

Now merged.

There is no QF codeshare for WT+ cabin on BA operated JSA flights. They treat it the same as they used to treat the different J services when BA has NCW beds and QF had Dreamtimes. So it just means the identical twins are not quite completely identical :p

I had the same issue today. QF32 this Sunday: Only availability in J and C, but nothing in D. So I am on a waitlist which they tell me will not clear for my DONE4.

Given that' s the history of C/J you would think on Japan Routes QF would use J for skybeds and C for non-skybeds. But why do that when you can slap on a surcharge :rolleyes:

Sunday departures to Asia and UK are always tight for D availability. They can generally fill business class cabin with J/C sales so restrict the D seats. Probably lots free for Tuesday or Wednesday departures.

Exactly the same strategy for flying in UA's upgrade (AKA "C") cabin on trans-Pacific.

I will fly on Monday night but would have prefered to fly on Sunday. Oh well, next time I need to book early.

But travelling on the Monday may also give you a better shot at an upgrade if you want to spend the points ^ .

SQ uses J & C interchangably. AA uses J for full fare paid Business and C for Business upgrade seats...

I think we can thank QF rev mgmt for this one. QF has introduced C in a big way in the last year and use it for the corporate nett (route deal) fares that used to be in D class (at least on my corp's account). This allows them to reduce or zero out D inventory on popular flights and so restrict availability for DCIR22, DONE4 etc (where they get much less revenue as its multisegment pooled) while not putting their corp customers too far offside (as the corps can still get the same route deal or nett fare , but booked into C)
