Ask About Seats
If you weren’t able to get the seat you really wanted while checking in, don’t worry – there might still be hope. Even if the check-in system showed a full flight, the agents at the gate will know if something is really free. You might get lucky and get an empty row or seat. Always ask, because you never know!
Leave the Air Turned On
While it might be very cold on the airplane, you can fix that with a few layers. However, it is important to keep the air vent open since it creates a makeshift force field over you. Meaning, that with the air on, you can avoid getting diseases from other passengers. On top of that, it can help prevent dry skin.
