(Just think about how many flights have ended with you having a sore throat or a cold after a couple of days of flying!)
BUT --- interestingly modern Plastic Planes, eg A380 bis. which are made of carbon fibre maintain a higher cabin pressure because the compound material much more resilient to the stretch and relax that takes place in the case of an aircraft made out of aluminium alloys.
Mind you knowing how much stronger and more resilient laminated carbon fibre structures are for me still doesn't quite eliminate that frisson I get climbing into what is a plastic tube with plastic wings!
A bit like when on the few occasions I flew on Concord knowing that the brake linings were just glued in place!
