     CBC is a famous air company which has over twenty planes carrying passengers and goods, flying
along 12 fixed lines all over the world. Its service is very good but some passengers are still not satisfied
with it and that is why in 1998 and 1999 the company received letters of complaints(投诉) from consumers
or passengers who pointed out over a dozen kinds of problems which are divided in groups in the following
table. This division is called Category. Problems that appear when the plane is flying are Flight problems.
Those about passengers' things carried by the plane are Baggage problems. Customer service refers to
service work which passengers are not satisfied with. Over sales of seats are about the fact that more seats
are sold and as a result the plane is too crowded to be safe. Refund problems appear when passengers fail
to receive the money paid to them because of what they have lost. Fares are problems about the price of
tickets. Reservations are problems that appear when passengers could not get the tickets they have already
booked. Tours are problems about the passengers'traveling by air or hotel problems. Advertising is what the
passengers think about advertisement on the plane. Credit problems are about the use of credit cards.
