Welcome back Safety Concerns
I think the BASSA forum term is "bump" or I agree for those who have not been on it.
I came back from the States last month, where the policy on the airline was no APU air on the turn round. We were delayed due to weather (big banging clouds and no sun, so the dilemma of window blind for cooling vs view was a non issue), and it was very hot for all 400 of us. It is probably going to take a medical incident for this no air con policy to be reversed, or some gold card holders having a hissy fit.
