5. Pick Your Seat
The most important decision you need to make when booking your flight is whether to buy a first-class ticket or fly in economy. First-class seats have the advantage of providing a reclining position, which makes sleeping much more comfortable. But even if you opt for an economy seat, sleeping on the plane remains possible.
Just know that not all seats are the same. Therefore, you should check-in online as soon as possible and choose your place. Avoid the seats near the toilets: they are louder because of passenger traffic and sometimes smelly. Choose a seat toward the front of the engine, near the wing.
