SkyTeam777, someone created a tool fairly recently that may fit your need. I haven't actually tried it myself so can't vouch for it but here's the thread:

You may also be interested in SkyHops which is similar to OpenFlights but with more interactive map and stats. Here's an example:

SkyHops currently supports export of your data. We're working on adding support for data import from TripIt, OpenFlights and other services in the near future.
