Some of my observations during my California trip.

Do Not,

Trust your wristwatch while you are waiting to transfer plane at the port.
Trust the Airline representatives they will misguide you to wrong place.
Watch TV or listen music or chat with other customers during waiting.
Let them transfer to you a different place and reroute your luggage to another place.
Buy combined tickets from different companies like US Airways and United Airways.
Admit any responsibility about a early flied plane,if you are not pilot.


Do,
Make an online reservation before renting a car.
Make hardcore deal with the car-rent-man never give up.

Always request a compact car, they will never have enough and big probably you will have free upgrade with the same price.

Always check your total balance at rent center, they may add something else that you
don't purchase like satellite radio.

Search coupons in your email box for a better deal with.
Trust your clock in your Cellphone.
Watch the boarding information without doing any think.
Concentrate announcements and decode each meaningless term.
