Extra seat hack
Want to avoid people sitting next to you on a flight? Like reserving seats at the movies, you should always leave one free between yours and another already booked. Most people don’t want to sit between two people; purchasing the aisle or window seat will make the middle seat less desirable. If no one books it, you will have more space if the flight isn’t crowded.
You should also try this trick if you are traveling by pair. This way, you have a partner to share the middle seat with. Even if someone takes the middle and you want to sit next to your partner, you can ask them to switch seats. After all, no one wants to sit in the middle.
