Flying out of an airport in th

【题目】Flying out of an airport in the United States is not always easy. You will need to complete the ticketing process, baggage check, and security clearance procedures before boarding the plane.

If you are flying on an international flight, you'd better arrive two hours before your plane is scheduled to leave. You might need more time in a busy airport in a large city. If you are traveling on a domestic (国内的) flight, you may only need to arrive at the airport 90 minutes before your plane takes off.

Every airport in the States is now moving its ticketing procedure to electronic ticketing device. By using a ticketing machine, you have the chance to choose a seat you like on the plane. If you use it to check-in your bags, you will only have to talk to the ticketing agent when you turn in your luggage to be tagged (加标签). At the same time a real person will be nearby to help you if you need it.

After you have checked in, you will have to pass through airport security. Have your ID card or passport and boarding pass ready to show the security officer when entering the security checkpoint line. Airport security is getting tight in the States today. You're not allowed to travel with any prohibited things like knifes or fireworks.

After the security staff has checked your travel documents, you shall put all of your belongings through a scanning machine and then walk through a metal detector (探测器) or a full body scanner. You need to take off your coat, belt, and sometimes your shoes to go through one of these scanners. Be sure not to have any metal in your pockets. If you do not understand a question you are asked at a security checkpoint, ask the person to repeat their question until you are able to respond with an accurate answer.
