Flying means sharing tight quarters—and what you eat can affect everyone around you. Some snacks smell too strong, while others leave behind a trail of crumbs, sauce, or sticky fingers.
According to flight attendants, a few foods are just plain rude to bring on board. Here are 20 of the biggest in-flight offenders.
1. Hard-Boiled Eggs
That sulfuric smell is unmistakable—and it travels fast in recycled air. Even if they’re peeled at home, they linger for hours.
Eggs might be packed with protein, but in a crowded cabin, they turn stomachs instead of fueling travelers.
2. Tuna Salad Sandwiches
Canned fish and mayo create a pungent combo no one asked to smell mid-flight. The scent clings to fingers, bags, and trays.
Tightly sealed or not, these sandwiches earn side-eyes from seatmates and disapproval from the crew every single time.
3. Garlic-Heavy Leftovers
Spaghetti aglio e olio might taste great cold, but the garlic hits differently at 30,000 feet. It sticks to the air like glue.
Crew members often compare it to invisible fog—it spreads instantly and can make the entire row grimace.
4. Fast Food Burgers
Hot fries and greasy patties release an aroma that tempts some and repulses others. The scent can fill half the cabin.
Add in crinkly wrappers and oily residue, and it’s a hands-down mess for whoever’s sitting nearby.
5. Ribs Or Wings
These finger-licking favorites are a flight attendant’s worst nightmare. Sticky sauce gets everywhere, including armrests and tray tables.
They’re impossible to eat neatly, and leftover bones don’t exactly belong in the seat pocket.
6. Curry Dishes
Even a mild curry can overpower a small space. The mix of spices lingers long after the food is gone.
Passengers often complain—even if they love curry on the ground. It’s a dish better saved for after landing.
7. Blue Cheese Anything
Crumbly and bold, blue cheese doesn’t hold back. It releases a sharp aroma the second it’s unwrapped.
On a plane, there’s no escape from that smell—and no amount of napkins will fix it.
8. Popcorn With Extra Butter
Crunchy, greasy, and prone to flying everywhere, popcorn creates noise and mess in equal measure. Buttered fingers smudge everything they touch.
One wrong move and kernels scatter under seats, down shirts, or across someone’s lap.
9. Microwave Burritos
Pre-wrapped burritos tend to leak, ooze, and fill the air with processed bean and cheese aroma. They also burst easily in transit.
Flight crews rank them among the most dreaded items because of both smell and spillage.
10. Fried Chicken
That crispy coating doesn’t stay crisp in the cabin—it turns soggy and leaves behind a powerful grease smell.
Plus, it often requires two hands, lots of napkins, and usually ends with an oily tray table.
11. Sushi With Raw Fish
Not all sushi travels well. Raw fish can smell sour fast, especially when it’s not stored properly.
There’s also the risk of foodborne illness, which no one wants to deal with midair.
12. Saucy Pastas
Spaghetti and fettuccine don’t mix well with turbulence. Tomato sauce ends up on clothes, seats, and unsuspecting neighbors.
Even sealed tightly, these dishes can slip, splash, and turn a small space into a red-splotched zone.
13. Barbecue Takeout
Barbecue’s smoky-sweet scent might be mouthwatering on land, but in a pressurized cabin, it becomes overwhelming.
Sticky containers and sauce-stained napkins just add to the frustration of fellow passengers and crew.
14. Spicy Chips
They might be crunchy and addictive, but spicy chips kick up clouds of chili dust with every bite. That dust clings to fingers, clothing, and even electronics.
The strong flavor can also make nearby travelers cough or sneeze, which nobody enjoys mid-flight.
15. Egg Salad
Creamy, chunky, and loaded with eggy aroma, this sandwich is second only to tuna in terms of in-flight offense.
Soft bread only amplifies the gooey texture—and the lingering scent turns many stomachs before takeoff.
16. Smoked Fish
Whether it’s salmon or mackerel, the scent is rich and unmistakable. Once opened, there’s no resealing it without a trace.
Flight crews report that smoked fish often leads to mid-flight complaints, especially on longer hauls.
17. Yogurt Cups Without A Spoon
It’s not the yogurt—it’s the panic when there’s no spoon in sight. Passengers then stir with fingers, lids, or even straws.
The result? A messy seatmate and a frustrated flight crew, all over what should have been a simple snack.
18. Big, Messy Sandwiches
Stacked high with meats, sauces, and toppings, these sandwiches fall apart the second they’re unwrapped. Ingredients tumble into laps or onto floorboards.
They also require two-handed wrangling, which makes accidental elbowing almost guaranteed in tight seats.
19. Strong-Smelling Cheeses
Brie, camembert, and other soft cheeses quickly become too much in the cabin’s recycled air. The odor clings to bags and lingers long after landing.
Even if wrapped tightly, they’re known to cause passenger complaints and nose-wrinkling from the crew.
20. Sticky Desserts That Smear
Frosted cinnamon rolls and gooey chocolate cake make a mess before the first bite. Icing melts fast in warm cabins.
Smears end up on touchscreens, armrests, or window shades, leaving a sugary trail behind the traveler.
