  A key feature of Simonovits' proof of the classic Erd\H{o}s-P\'osa theorem is
a simple subgraph of the host graph, a frame, that determines the outcome of
the theorem. We transfer this frame technique to $A$-paths. With it we deduce a
simple proof of Gallai's theorem, although with a worse bound, and we verify
the Erd\H{o}s-P\'osa property for long and for even $A$-paths. We also show
that even $A$-paths do not have the edge-Erd\H{o}s-P\'osa property.
