In the last few years,there has been a rapid development of feeder airlines in the United States and in many other countries.Some smaller cities have no other means of public passenger transportation.In countries where there is a large frontier,such as Canada or Brazil, air service may provide access to some areas even before they are reached by roads. Similarly.in counties with rugged terrain, such as Colombia, airplanes can providemore effective transportation between regions than highways or railroads.
Airline passenger service can also be divided into scheduled and non-scheduled flights. A scheduled flight leaves at the same time on the same day to the same destination. The schedule for the flight is pulished by the airline in its timetable. The passenger can make a reservation in advance for a scheduled flight with the reasonable expectation that the flight will leave at a certain time and go to a certain place regardless of the mumber of passengers who have tickets for the flight. Many scheduled flights often carry only a small number of passengers .
A non-scheduled flight, on the other hand, depends on the availability of passengers and aircraft. It is more or less the air version of taxi or rent-a-car. It takes passengers where they want to go at a time that is convenient for them, as long as a plane is available. Non-scheduled flights may carry only a few passengers in a small plane, or they may carry hundreds of people on a jumbo jet. These latter flights are often called charters. Charters are especially popular with groups on vacation since they usually cost much less than scheduled flights on the same routes. We will discuss charter filghts in more detail in Unit Eight.
Scheduled airlines often provide non-scheduled services-particularly charter flights-during the tourist season.Occasionally, they also provide extra sections of scheduled flights at times when travel over a particular route is especially heavy-during a holiday weekend, for example. An extra section of course depends on the availability of aircraft
On the flight itself, there is usually a distinction between first class and economy, which was formerly known as tourist class. The first class passenger has more space and receives more in-flight services.In most modern jets, the seating plan in first class is usually two seats on each side of the aisle; in economy there are usually three seats side by side. The first class seats are usually farther apart so that the passenger has more room for his legs. To the passenger, the chief difference between first calss and economy may well be the cost---first-class fares are much higher than economy fares.
