One option for exporting out of Tripit is to use openflights.org which will easily import your flights from Tripit and then you can export in csv format to put into flightmemory.

Personally I prefer openflights to flightmemory as the maps are much better and it has slightly different stats.

Pleased that flytr has a mobile app (which is an obvious miss on the other sites) but how can I register for flytr?
