I had a big problem on my CX flight in paid J from CDG-HKG this week. I am curious on how to approach the situation. CX seems to do things "differently". I read this board about how not to ask for Upgrades etc. I want to handle this the smart way. Basically here is the situation:
I paid for TWO business class seats from CDG-HKG. One for me and one for my mother. I got lucky (Flight was full) and got upgraded to First at the gate. After that I encountered three problems of varying difficulty.

1) My first class seat was broken. It would not recline at all. It was stuck in that slightly leaning fowarward position for takeoff. It was terrible on an 11 hour flight. Obviously this is the bulk of my compensation issue. The reason I bought the J seat was comfort. I ended up with less comfort than a coach seat. I would normally ask for the difference in the fare on that leg between J and discounted coach as compensation. Alternatively and upgrade to J from Discounted coach would be acceptable too. What do you think?
2) Due to the ridiculous French being on strike (Industrial action they called it). They had zero asian meals and only three choices of meals. Murphy's law dictates they were the three things I'd never eat. I realize this isn't directly CX's fault. However, I certainly did not get the "CX experience" of food I paid for. I'd roll this in my solution from above. Basically a partial refund or a do vover. But, I do mention it so you get a feel for the problems.
3) I was wanting to buy a necktie from duty free. They had "weight issues" and didn't load the carts... I realize it's no biggie. Again, just seemed like I was cursed!

How would you contact CX and what is reasonable? Thanks, Cigar
