The line chart depicts the number of complaints to an airline over a six month period in 2009.
Overall, there are three different types of complaints to an Airline shown in this graph – in person, by email or fax and third, by telephone. What can be emphasized is that over time travelers started to prefer in-person method of communication.
Firstly, most of the complaints were received by telephone in the first three months – January, February and March. Even though less than most complaints were received in person, there’s a significant increase in the number of complaints in person – from approximately 400 complaints to an Airline in January (last place in line chart) to almost 2000 complaints in June, after six months. Thus, the in person method rapidly moved from the last, third place to the first place in June.
Secondly, by email/fax complaint method was the only active decreasing method in this graph. It moved from second place in June (800 complaints) to last in March, two months later. This method has retained the last place since March, steadily declining to 400 complaints in June respectively.
