Traveling on an airplane may not be too comfortable experience because of the neighbors who will fly next to you. In addition, in economy classes the seats are quite cramped and it can be uncomfortable to sit in them for several hours in a row..

However, there is a life hack that will help you leave the chair next to you free. It was tested by expert bloggers from the Skyscanner air ticket booking service, Express writes..

Let us immediately note that this life hack only works on airplanes with three seats in a row.. And in order to use it, you need to travel together.

To get an additional place, register for a flight in advance through an online system and use the service selection service. In the row, choose two extreme seats - the porthole and in the aisle, and leave the middle one free. With a high probability, if the flight is not sold completely, there are no people in the middle of those who wish. In this case, the whole row will be at your service. In addition, this will provide you with additional legs space.

But the life hack does not always work.

If your plane is sold out, someone will definitely come to fill the empty seat.. Well, in that case, you can offer this person a window seat so you can sit together again.

At worst, you and your travel partner will have to sit across the seat from each other. That in general there is not such a high price to pay for taking a risk.

Thus, life hack will not give you a 100% guarantee that you will fly in more comfortable conditions. However, it greatly increases the likelihood of such a scenario.
