What is actually my fare code
 

Hi,

I am a newbie with Qatar. The last time I flew with them was over 10 years ago. I am more active with *A carriers as a Gold member.

This October I got a discount ticket from BKK-CDG-KUL. I believe a fare error over IB transferred me to fly with Qatar. My ticket shows me the fare code are: IDL5XNM7 & ION7X6M6.
I am not familiar with this code like, Y, J, C, D so I will know exactly terms and where I should park my mile.

Where should I put my mile to? Most and only active Oneworld I have is Cathay & JAL where I mostly transfer mile from my credit cards.

Your suggestion is highly appreciated.

Maybe I fare class (not 100%sure)
But look in Qatar QR manage booking. Even Qantas QF manage booking may show fare class (a letter in brackets)
A broad guide (but check the airline we site)--> https://www.wheretocredit.com/qatar-airways/i
Put to CX or JL ffp. Which ff miles/points will you use first?
Y can generic economy and/or Y fare class. Y fare is the highest and often very expensive

Hi Mwenenzi,
thank you.
I was thinking it should be "I" class as well.
Normally i will receive fare code in 6 digits which I can identify it easily, but this time is IDL5XNM7 which is 8 digits, so not also sure 100%.

It is the first letter of the code on the ticket...in your case "I"
