I can say that my interaction with QR is professional and I had all the change I wanted. But they had a mistake in manual recalculation for yq that I only found out later. (Not a lot of money so I will cut them some slack.)

Because it was a face to face meeting, I can pull out the fare rule and discuss about any specifics objection that they had . It worked with CX too. Being physically present helps a lot.

My experience is that front desk office people can all do RTW ticket, I cam count at least 3 agents in CX office in HK that can do it without a lot of effort and one can walk in and buy a done fare in as little as 15 minutes.
