Abstract
We consider a dynamical management problem for accepting reservations of airplane seats. When the penalty for the airline company canceling an accepted reservation is increasing as a period approaches to the flight day, how many reservations must the company accept or cancel in each period? We show that the optimal policy has two levels and
in the n-th period such that if the accumulated number w
n
of accepted reservations is smaller (larger) than
, then the company can accept more reservations (must cancel accepted reservations) until
and if
, then the company should make no acception and no cancellation.
