For those who have not had the pleasure of flying a saab in the summer, we have no apu and it is not uncommon to push off the gate in IAH with a cabin temp of 35c. On the CLL and BPT turns you are probably looking at a 20 min or so taxi for a 10 min flight below 5000 ft meaning you will never be able to cool the cabin off and then find out that the out stations air cart is not working. After repeating the process several times on an 8 leg day I adopted a stratagy. I would take towels from the hotel on the ron and wet them down and put them on me during the work day to help cool off then trade the towels in for fresh ones at the next hotel on the next ron. It was a lovely experience, I am paid a measly 26$ an hour to do this, our passengers actually pay to endure this sh***
