Is the Embraer 145 baggage bin pressurized? I was told it was not during my Expressjet training and for that reason they do not allow animals in kennels. There's also a sign on the bin wall that says NO ANIMALS THIS BIN.
When I pop open the vent and open the door it is ICE cold. I have to admit, it feels good on a 100 degree day! But is it really not pressurized or just not temperature controlled?
Also, I've seen boxes from the Red Cross of human blood to offload. The boxes say "avoid extreme temperatures". How cold does it get in flight? If not pressurized I would imagine it would be similar to the outside temp which is below zero so how is that not extreme temperature?
