Thanks for everyone’s options. Here comes update:
After 3 phone calls to Taipei office, MPC, and BA, I made the fourth one to Taipei office again to work thing out.

I didn’t mention the previous calls to agent, just simply describing the situation and requesting to rebook to CX251. She answered this ticket was not issued in Taiwan so it would take a while. In 10 mins, she was back.

“” hello, Mr. xx, sorry for keep you waiting. I discussed your case with my supervisor. We will send request to HK office to confirm your seat on CX251. It should get proved easily because business class wasn’t full (J and C inventory were still available).” In 10 mins, a new e-ticket was sent, confirming CX251 flight. Finally, CX met my expectation.

Something I like CX is “when thing goes wrong, we will fix it without conditions” That is the attitude making CX 5 stars airline. In this case, I dislike the MPC most. The agent kept telling me the matter was caused by BA. It is really not CX’s business! Hey, this is a 160 ticket. There is no way CX could get out of this, particularly it involved your own flight CX251. Regarding to the first Taipei office agent, I think she was just inexperienced.


I talked my case with a friend, who working as KA ground crew. He thought I was “The Squeaky wheel gets the oil!”, implying I was “an awkward customer”. He didn’t agree CX confirmed my I inventory and lost some profit (C down to I), since this was caused by BA. However, from my point of view, I didn’t do anything wrong, why should I get punished either losing half day in Oslo or paying hotel fee in London? This is CX ticket and CX should work it out to meet customer’s satisfaction.

How do you guys think??
