The illustration depicts, the number of airline staff, the average number of complaints lodged by passengers, and the typical weight (in kilograms) of luggage allowed to be carried by a passenger across four selected destinations from Australia.
When compared the average number of passenger complaints with crew numbers, it is evident that higher the staff numbers, lower the concerns raised by the people on board. For example, the flight from Australia to Germany carries the highest number of cabin crew (15 people) whereas, it records the lowest number of complaints which is less than 5 complaints, in comparison to other locations. On the other-hand, however flight to New Zealand only carry 6 staff members, which in-turn has resulted in a higher score of complaints (more than 5) on average.
Additionally, when the weighted baggage value in flight across the destinations is drawn against the crew numbers, it is visible that higher the staff number in each flight, the higher the on average weight allowed per each passenger. This is because, when there is adequate staff is available, it is manageable to handle a higher weight of luggage on board. For example, New Zealand flight has the highest staff numbers, which is 15 people along with the highest number of luggage weight allocated for each passenger, which is above 35 kilograms.
Thus it can be concluded that according to the above depictions, the airline crew numbers in each flight across all four destinations is directly influencing the number of weight of luggage allowed for each passenger, and the count of customer complaints received on board.
