Perfume
Avoid heavy perfumes for the sake of your fellow passengers. Because hile flying, you will be in a small but packed area.
A maximum number of people find scented products on others irritating, and there could also be people with allergies and asthma on the flight.

Tight clothes
Wearing tight clothes especially when your flight is longer than 4 hours is uncomfy. People on a long-distance flight are at a risk of DVT (deep vein thrombosis). DVT is a blood clot that forms in a deep vein, usually in the leg.

Complicated items
As the airplane bathrooms are tiny, you shouldn't wear complicated clothes. If are wearing a jumpsuit, you will have a hard time trying to take it off. Instead, wear something which is not likely to cause difficulties in this small space.

Clothes or jewellery containing metal
Large metal adornments or jewelry with metal can slow your progress through security. What if you are wearing a sparkling sweater that might have metallic threads woven into them.

Summer clothes
The temperature in the plane can be surprisingly cold. Having multiple layers of clothes on is essential for a comfortable journey.

Contact lenses
In an airplane, the average humidity can get as low as 20%, which will make your lenses dry out and cause irritation in your eyes.

High heels
Nobody likes standing in bare feet on an airport floor. Airport security will ask you to remove your shoes. Not only can heels potentially be used to store prohibited items, they have a metal construction base, which will definitely set off the alarm.

T-shirts with offensive text
Dressing decently is important. There are people who were banned from boarding a plane because of the way they were dressed. There are many reasons to why you might get banned, too much cleavage, a low-cut dress, saggy pants, an offensive T-shirt, bare feet, or even leggings when flying on an airline’s employee pass.

Bonus
Remember what happened to Kim Kardashian in LA. Even if you are a star and follow the rules, you can still be stopped by security and thoroughly searched. You can't be pardoned!
