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!

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
