Abstract
The problem of planning the cheapest flight path, given s, t, and a set of intermediate airports at which it can make a stop is presented. This problem can be formalize by letting P be a set of n points in the plane, containing two given special points s and t. To solve the cheapest path problem in the setting, the Delaunay triangulation D(P) of P, in time O(n log n) is computed, and the shortest path problem on the graph D(P) under the cost function l(.,.) is solved using the standard Dijkstra's algorithm. Since the size of D is O(n) this implies that the overall running time of the algorithm is O(n log n).
