If it smells, makes too much noise, or involves you slurping or crunching loudly, save it for your hotel room. We are all for living your best life (like these travelers on the Instagram account Passenger Shaming), but have some consideration for your fellow passengers and dine appropriately while onboard.
Also, remember to always fill out the necessary customs declaration forms if you are bringing any food containing meat, fruits or dairy.
A passenger traveling from Bali, Indonesia to Australia was recently fined almost $2,000 USD after failing to declare two McDonald's egg and beef sausage McMuffins and a ham croissant. The incident came days after Australian authorities enacted tougher security checks on visitors due to a recent Foot and Mouth disease outbreak reported in Indonesia — a popular destination for Australian tourists.
A similar incident occurred to another flyer visiting Australia when she was asked to pay a $2,664 AUD fine (about $1,800 USD) for an unfinished Subway sandwich. The passenger said she had purchased the sandwich during a layover in Singapore and failed to declare "chicken and lettuce" from the unfinished sandwich in her carry-on, resulting in the hefty fine.
