However there are two problems: 1) this flight path is not connected to any other navigable way (so in mathematical / graph theory terms, Davao is not connected to Manila), and 2) even if it were connected, the tag route=flight is not used by any tool that I know of[2] and I assume that this is not recognized by keep right. I think the simplest way to connect Davao to Manila is to ensure that there is an unbroken set of ways from Davao to Surigao City, then a ferry route to Liloan, Southern Leyte, then a land route to Tacloban then to Sta. Rita, Samar (via San Juanico Bridge), to Allen, Northern Samar, then a ferry to Matnog, Sorsogon. I'm assuming that there already exists in OSM a connected land route from Manila to Sorsogon. With this option, I don't think a ferry route from Davao Port to Manila Port would be needed to solve this problem. Eugene / seav [1] http://www.openstreetmap.org/browse/way/36961252 [2] Sky-based map data is a bit controversial and some OSMers seem to think that they shouldn't be entered into the main OSM database while others argue that they are still valid map data.
