By now I have experienzed OZ in all three classes and four different longhaul aircrafts.
None of them had dirigible air nozzle or visible vents at all. Overall cabin airflow felt very low, just enough to prevent crew and pax suffocation.

The worst was my recent experience on the A330 (not you Triple3 should you read that). The air was stifling and there was an unpleasant stench of sweat, food, and spices ruining the overall ol flight experience. My 777, new 777, and 747 experiences were probably only better as the load of pax was very, very light in all cases.

I just don't get it - great food, good FAs, new aircraft with great working AVOD (the 333 that is not the old 777 and the dreadful 747) and then they nearly choke their passengers.

Do all Asiana birds exhibit this major flaw?
