We give a polynomial algorithm which decides the integer solvability of multicommodity flow problems where the union of "capacity-" and "demand-edges" forms a planar graph, and the number of demand edges is bounded by a prefixed integer \(k\). This problem was solved earlier for \(k=2\) by Seymour a
