This is a student essay about the growth in air travel. Read the first paragraph below, and choose which sentence is most suitable as a paragraph leader.……………………… IATA, the trade association for the world’s airlines, estimates that revenues from air travel rose from $465 billion in 2006 to $705 billion in 2016. In addition the total number of passengers rose from 2.2 billion to 3.8 billion during the same period (IATA 2017). There are a number of different reasons for this rise, including low air fares and economic development, particularly in Asia, but there are several factors that may lead to a slowdown in this growth in air travel.
Read the second paragraph, and choose which sentence is most suitable as a paragraph leader.……………………… They are able to drive prices down by having a low advertised fare, and then making additional charges for “extras” such as booking a seat or checking in luggage carried in the aircraft’s hold, things that were normally included in the fares of the legacy carriers, the airlines with a long established reputation. There are other efficiencies, such as the use of smaller less expensive airports, that can also keep costs down.
Read the third paragraph, and choose which sentence is most suitable as a paragraph leader.……………………… British Airways has outsourced a lot of its IT work in an attempt to cut costs. Many airlines are now charging for checked-in baggage. While the legacy carriers have had a significantly larger share of the lucrative business travel market, which is less susceptible to changes in the global economy, this is another market that the LCCs are starting to penetrate. In practice, the LCCs and the legacy carriers are becoming more like one another.
Read the fourth paragraph, and choose which sentence is most suitable as a paragraph leader.………………………They argue that an increase in air travel is a key element in the globalisation process and is essential to sustained economic growth. Most of this growth is expected to come from demand in the Asia Pacific region, where China and India, both countries which have seen above-average rates of economic growth, are also showing significant increases in both domestic and international air travel.
