The presented chart depicts the number of criticisms which a specific airline’s complaints branch was given over a period of six months in 2009.

Taken as a whole, while the number of criticisms received by telephone and in person had an inclination to increase, the opposite was true for the figures by email or fax.

In January, complaining through telephone occupied the highest position in the number of objections with approximately 900, followed by complaining by email with nearly 800. By contrast, the figure for face-to-face complaints was at the lowest part with exclusively 400 since the start of the period. Over the next three months, face-to-face criticisms showed the proliferation which surpassed email complaints and increased by 400. By the same token, the number of objecting by mobile phone rose roughly to 1000 while the figure for objecting by email remained relatively stable.

From March onwards, there was a prevalence of complaining by face-to-face method that it took the lead in the number of criticisms, then ended by more than 1800 in the final month. During the same period, the figure for telephone complaints continually grew to approximately 1400. Also, after witnessing a relatively static stage, email objections fell dramatically to exclusively 400 and remained stable by the end of the period.
