Band 6+: The chart shows the proportion of seats an airline was able to fill at three time points. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. You should spend about 20 minutes on this task.

The bar graph depicts information about the number of seats which were filled by the passengers in an airline in three different years (2005, 2010, 2015). The passenger load factor units are calibrated in percentage.

Overall, premium economy class seats were the most preferred option for the travelers, whereas the business class seats were least preferred in the latter years after 2005.

Primarily, in 2005, 90% of the business class seats were booked, while only 80-85% of the seats were taken by people from other classes. Thereafter, in 2010, the proportions of passenger load in economy and first class seats remained unchanged at 80%, however, the demand of premium economy took a leap to a maximum of 95%. Conversely, the business seats load factor dipped by 25% as compared to that of 2005.

Turning to the year 2015, the premium economy seating remained unaltered. Although, the seats load factor for other classes rose by approximately 5-10 percent each.
