Well, after deliberating on whether to bother or not, I headed along to the CX ATO at HKG to reissue my AONE4 ex-CAI. I wanted to change one segment, add a new one and remove an existing one. The CX agent was not overly impressed, especially as there were still 18 segments left and it would involve excessive handwriting. However, he had a look at it, asked me how I wanted to change it and - DISASTER. According to him, the fare calculation does not match up with the itinerary: for example, I am flying from HKG-JFK yet there is no mention of JFK on the calculation.

Now, I have absolutely no idea what a fare calculation should look like. All I did was check the routing was correct. So, after checking in for my flight today, the CX agent walked me to the BA desk to see what they could do. They are sending a telex to BA Sydney (my next stop) and seeing if they can sort it out.

So, it looks like I will be spending some hours in a ticket office in beautiful Sydney. Moral of the story: not sure there is one. If this was incorrectly issued then make sure your fare calculation matches up ex-CAI in the future. Of course, this assumes you know what it should look like.

Still, despite the extra hassle, an early morning glass of champagne in The Wing is soothing my furrowed brow...
