3. Not taking care of your hygiene
Nobody wants to sit next to someone for hours who has really bad body odor, bad breath, or poor personal hygiene in general. And while you might be concerned about being seated next to a person with poor hygiene, you should first take care of yourself. As the old saying goes, “Be the change you want to see in the world,” and this applies to the littlest things. Always pack some gum with you, wear deodorant, and most importantly, take a shower before your flight.
