I looked up the Avios earning on both BA and Qatar, LHR-HKG on CX as example
Qatar earns 125% on C,D,I,J,P fare while BA excludes P.
Also, Qatar is more generous for mid-economy tiers but earns nothing for the lowest tier.

Y B QR 100% BA 100%
H QR 50% BA 100%
KLMV QR 50% BA 25%
SNQ QR 0% BA 25%
O QR 0% BA 0%

Interestingly inconsistent, but at least for KLMV tiers it isn't too bad.

Calling CX Customer Service Number to Book Specific Fare Code
 

I have a good experience of recently using the CX customer service number (at the bottom of the website) for the United States. For Japan Airlines FFP, I would only be able to earn mileage / qualifying points for booking class L and above.

I called the number around 6 PM EST yesterday and the automated number originally advised me that I would have a 10 minute waiting period, but I was speaking to an agent within 2 minute's time. After specifying the date, route numbers, and specifying that I want to have the fare class L, the agent confirmed my name, date of birth, flight details, and also sent an email to confirm the informations.

Once I confirmed the information was correct, I then got a link via email again to purchase my fare. Sure enough, the fare class L was there on the e-ticket PDF. I would recommend their customer service if needed and the phone call was no more than 15 minutes.

Altlough, I wish CX would still peg their fares to specific fare class and associated benefits. On Japan Airlines website, you have the choice of the cheapest (of what's available) fare classes, upgradable, and then fully flexible options, all which have different accumulation points based on fare class for your oneworld programs.

QR and BA have the nice feature that you can transfer avios from one program to the other at will. No hassle.

If avios is what you care about, it is easy to have both QR and BA accounts and choose where to credit a CX flight. But that only applies to avios, not to BA TP.

Trip.com, Skyscanner, Ctrip, Wing On Travel (based in HK) are in the same group of companies. I once booked a ticket with them and later on realized the ticket was issued in Sweden and the cost of it was HKD14k while I was paying HKD15k to them. The airline official website was selling at HKD16k if issuing in HK. However, there had been hiccups before departure and it was nightmare to contact them to solve the issue. Luckily nothing happened at the end and the so-called 'risk of boarding denial with my ticket' was due to the incompetent CX customer service.

I had no idea they were all part of the same company. What's the advantage of one over another?

I can now see fare classes(Y,B,H..etc) on CX website with fare type:)

Fare classes are shown on flight details section.

Good news! I can’t imagine the snowball effect of complaints that had to take place for the company to walk back on its changes of removing transparency for those of us trying to FFP points :(

This doesn’t seem implemented yet on the iOS app (my region is the Americas, if that makes a difference)

Where do you see that before finalizing the booking?

I suspect it's BA that forgot to update their chart. AA had the same issue with JL chart. Back in 2021 JL flipped their I and X fare (discounted and deeply discounted J). CX updated their JL charts but AA didn't. I called, emailed, called (yes, I needed the extra miles to maintain OWE) and AA finally updated their JL chart in Mar/Apr 2022.

I can see CX P fare on AA (and AY) charts so CX did inform other airlines but BA probably didn't see the memo. But I'm surprised no BA flyers bug BA about it if P fare was introduced years ago ... or maybe they did and BA just ignored it. I mean it's BA .... :D

Thanks for this! Worked well on a web browser. Very happy to have this info back again! :)

It is visible before you enter the passenger details.
