Are airports valid waypoints?

[jetlag]

According to the FS help file, I can use an airport as waypoint (other than departure or dest). If I do that using the FS9 planner, the waypoint appears in the Navlog but next time I load the flight plan, that leg is ignored (although Notepad shows the leg is indeed in the file).I found this out when noticing that flight plans autocreated with Super Flight Planner and including airports would not load at all in FS9.Thanks for your help.Phil

Yeah airport are valid waypoints on flights egll-vhhh for example they use UHHH as a waypoint alot. So thats my opinion anyways.Kind regards:Alexander

How silly, because in my FMC I can't put in UHHH... What should I do?

Thanks for your reply.When you say "they", you mean in real life?Do you (or anybody else) know how FS9 treats that? I can't get such flight plans to load properly...Phil
