Let me guess - catering complaints?
These figures can be misleading - for example AC is not moving as many passengers as before, so it would make sense that their complaints would go down in proportion to their passengers. Westjet is flying more passengers so it would make sense that their complaints would proprtionately rise. Is it really 2-5 complaints that we're talking about here??? LMAO, if this is the case the precentages really throw things out of perspective in this example!
