If you've ever wondered what it smells like when an aeroplane door opens after a long-haul flight, former ground crew worker Trish from Cronulla has the answer, and it's not pretty. She says the worst offenders are the Perth red-eye flights, which apparently arrive smelling like a combination of "farty bum and bed breath." Ricki and Tim investigate whether long-haul flights are just as bad, with Trish confirming that all the late-night wine, beer and beer burps definitely don't help. Tim is horrified, while Ricki presumably starts questioning every flight she's ever taken.
