A former flight attendant talked to Mike and Katie about the 'dos and don'ts' of flying - and it gave MG the perfect opportunity to vent on his pet hates.
Shawn Kathleen runs Passenger Shaming, an Instagram account dedicated to people behaving badly on planes - with examples of everything from over-stuffed luggage racks to passengers bringing pet birds on flights.
Kathleen told us about some of the worst things she's seen, and gave us some top tips - from managing body odour to making sure you don't step in the funny liquid in the toilets.
MG admits he hates flying, as he's been doing it for so long, and he's got a long list of bad habits that get his goat.
Singling out his pet hates, Mike says he gets made when people take their shoes off, adding that he's even had someone behind him put his foot through the gap in the seats so he could rest on the armrest.
He also hates it when people "don't seem to know how to control their children" - a point Kathleen readily agreed with.
