I rarely fly Sky Team or CZ for that matter but just wondering if anyone ever been able to pay for a cash upgrade at check in. Would be great to check out the biz class seats, especially on the upper deck.
I did on a CAN-NRT, it was around 300 or 400 USD, don't remember really, it was nearly 3 years ago. The service in Business was really good compared to the service in Premium Economy I experienced on the SYD-CAN.
I have flown that route twice this year. Both on the Thursday morning departure. In the upper deck business class area the flights were only about 50% occupied (March) and 40% occupied (June). I counted the seats as I was also surprised at how few people were in the cabin. I would guess that data for a Wednesday will be similar.
