From the airlines‘ point of view, probably the most important event of 1956 in the field of passenger transportation was an agreement on a plan to combat the no-show. A no-show is a person who makes a reservation but, without canceling it, fails to show up for the flight. In many cases the seat could have been sold to someone else but remained unsold because of the uncanceled reservation. In 1955, no-shows cost the airlines $11,096,890. This was an increase of 92 per cent over 1954. Under the agreed program, which began Sept. 16, 1956, an airline cancels a reservation if the traveler fails to purchase his ticket by a certain time. Early in 1957, the airlines will decide whether to impose a penalty charge on no-shows.
