Flying is nothing
You will want to take some gum with you for your ears (Helps in the popping)
Step by step for takeoff:
Get on plane and sit and wait for it to taxi away from the gate. When it starts taxing, it will roll not real fast (Like 10-20 mph tops) to the runway. After waiting in a line of planes to take off, your plane will roll onto the end of the runway and stop. Sometimes the pilot has to wait before getting clearance, othertimes he already has it, that will determine the length of time stopped at the end of the runway. Once clearance is given to take off, your plane will throttle up (You will know when that happens) and start to roll. It will very quickly accelerate to the takeoff speed needed (Almost always above 150mph for big jets). You will feel yourself getting pulled back in your seat, that is called gforces 🙂 When the plane lifts off, it will go up at around a 20-30 degree climb, raising it's landing gear almost as soon as it leaves the ground (You should hear it and maybe feel it). The takeoff is a little bumpy sometimes as you climb through the wind's of the lower atmosphere, but once you get up to cruising altitude it should get a little smoother.... The pilot will let you know if bumpy weather is ahead. Enjoy the cruise at 30,000+ feet at over 300mph 🙂
On landing it is also bumpy, exspecially when the landing gear hits the runway, it sometimes feels the plane skips sideways, which it may bounce on the first touchdown, but it the pilot is any good, he/she will sit it down gently. You will hear the flaps etc... working shortly before you land as well as the gear coming down, and when you do sit down the pilot will put on the reverse thrusters. That is when the thrust going out the back of te engine is redirected to point forward of the aircrasft, hence creating an airbrake or sorts.
I have flown several times from east coast to west coast of the U.S as well as from Florida to Michigan, and from Florida to Hawaii.....
I do suggest you get a window seat so you can watch the ground under you go by. It doesn't zip by like you might think, because of your altitude you should be able to see great distances...
Relax, pop a stick of gum in your mouth and enjoy the ride! 🙂 Great experience!
