The fucking airlines are cutting corners on HVAC, too. Do y’all even remember that flights used to be freezing cold start to finish?
Now you sit on the hot tarmac at the gate for an hour with AC off to “save power”, sit on the tarmac in line to takeoff for an hour, sit in a hot humid tube for 8 hours… I used to bring down jackets on flights. Now I wear a t-shirt and still end the flight sticky and sweaty.
Same carrier, same lane. Not like cutting corners on HVAC is a literal health risk or anything.
Although to be fair, cutting safety features in favor of profit is nothing new for the industry since Reagan.
