I'm with you about the air nozzles. I'm wondering though if it's totally an airline issue or it's not also an aircraft issue. For example, I've never seen an air nozzle on any Airbus aircraft while I've never seen a B737 without air nozzles. I think all or almost all B747's I've been on had air nozzles, but don't remember Asiana's B747's as it's been a very long time since I was on one of those. I know that with some aircraft it is an option, and any airline that chooses not to order a plane with air nozzles is making a huge mistake IMHO. But is it an option with all aircraft? I really hate the smaller Airbus aircraft as the heat is sometimes almost unbearable without the air nozzle when parked on the tarmac. I've always been quite comfortable on either A330's or B777's without air nozzles, but usually fly TG with those aircraft so don't know if that's any different than Asiana or not. But on the A330's and especially with the B777 there is noticeably more airflow in the cabin than on the smaller Airbus planes.

In general I've seen much fewer air nozzles on Asian planes than in North America, so I think Asian airlines generally opt to not order their planes with the air nozzles if given the option. They really should wake up to the fact that for many Western travelers the lack of air nozzles can be a significant factor. I'd personally choose one airline over another if it meant the difference between air nozzles or not, especially on a smaller plane.
