M: Travelling by air is one of the major conveniences of modern times. The whole field of aviation is geared to meet our needs for safe, efficient, and fast transportation. Let me give you an account of my recent trip on a major airline to illustrate my point.
I began preparations for my trip early by calling the airline and making a reservation. A few days later I got the e-mail telling me my flight number and the times of departure from my city and arrival at my destination. I was advised to arrive at the airline terminal an hour before takeoff in order to check in for my flight. On the day of my flight, I went to the ticket counter for my boarding card and then headed for the waiting area of the gate from which my airplane would depart. Of course you have to go through security system first. While I was waiting, I noticed how busy everyone was. The mechanics were checking the plane for last minute repairs, and a large truck was fueling the plane with gasoline to make it ready for takeoff.
When my flight was called I boarded the airplane. I was pleasantly greeted by the flight attendants and offered light drinks and food. The weather was good, and there was no air turbulence to cause us worry or discomfort. Although my flight was trouble free, during the holidays air travel becomes more hectic. Often airlines sell too many tickets for a flight and are then overbooked. Some unlucky passengers will be bumped and asked to reschedule on a later flight. Bad weather might also cause a later takeoff, and this delay often results in missed connections at the next stop. On the whole, however, air travel is worth the expense. It is fast, safe, and usually reliable.
