First all of, choosing an airline carrier might depend on a number of factors including the company's service record, price of the ticket, length of time to destination, and even in-flight service.
Now, once you've purchased your ticket, you still need to make the long journey through the airport. Once you arrive, you usually check your bags at the main ticket counter. Then, you have to pass through the security checkpoint, where you will have to walk through an X-ray machine, and they will check your carry-on bags for any prohibited items, including firearms, explosives, and knives. Of course, this is for everyone's safety. You might also be asked to open your bags to be manually checked.
Once you pass through this checkpoint, then you will go to the designated boarding area and gate to wait for your plane. Just wait there until they announce your flight.
Of course, once aboard the plane, no one ever wants to experience any emergencies, but the plane is equipped with emergency exits in case you have to leave the plane. There are also life jackets under the seats, and oxygen masks in case the plane's cabin unexpectedly loses pressure. Be sure to read the safety instruction card located in the pocket of the seat in front of you.
Airplane travel can be exciting and knowing what to expect before you can make this experience even better.
