Pigs in the lowerdeck is a definite no-no as the temperature range for pigs is limited and the required ventilation flow is considerable. Given that there is a lot of air re-circulated means that the humans upstairs end up sharing the recirculated air with the pigs, who then write rude letters in to the airline to complain about the smell.
Who gave the pigs the address?
