I have created a tool to export your flights from flightmemory.com into the openflights CSV format. This allows you to migrate your flightmemory.com data to openflights.org, or at least keep them in sync.

Please see: http://goo.gl/Jn6uF

The typical way to do this is to go through each page of your flightmemory.com flightdata, save a copy of each page, then manually upload each one to openflights.org (what a pain!). Note that flightdiary.net can import from openflights.org, but not from flightmemory.com, so perhaps this is an easier way to also go from flightmemory.com to flightdiary.net.
