I flew CX last Dec., Apr. & Oct. During the Dec. & Apr. trip were excellent, being only a Silver. I received upgrades twice during my two return trans-pacific flight, that rarely happens with Silver nowadays. The service was excellent, they volunteering provide me with bottle of water once I discarded my old bottle. You can feel they are going the extra mile. I guess it was due to the head on competition from HK Airlines which started in 03/18. However, for the recent Oct trip........, Let's begin,

I only use my US passport when leaving and entering US. Period. Since like 20+ years ago........ And I use my BN(O) for my trips outside of US(Yes, I still keep my BN(O) and still renew it), except TW/CN. I checked in online for my trip to BKK, first segment(SFO-HKG) using US passport and second segment(HKG-BKK) using BN(O). And at the airport, I printed out my boarding pass and the baggage tag, getting ready to drop off my baggage at the drop-off counter. However, the agent in CX uniform started to do lots of things. Asking for my passport, as expected for verification and I provide both my passports and explained I will use my BN(O) to enter BKK. He refused. He insisted one should use one passport for the whole itinerary, he can use my BN(O) to check in and remove my US passport. He even mentioned I should use US passport since I am an American citizen. I did not speak loudly nor argue but I explained I had done this many times before. He insisted he can't do it, I feel he's more agitated. Anyway, I left it as-is and headed for my vacation. From then on, all my flights(BKK/SIN/HKG) on CX from checking in to on flight were terrible. It seems they(Check-in counter agent/IFA) were very cautious or ignored me and expected me to be upset or agitated. I would even come to say they were rude to me.

Conclusion, am I too sensitive or CX does input passenger 'dissatisfaction' or 'bad behavior' on the itinerary? I couldn't think of any other incident beside this. I hope this will not happen again on my up coming trip.
