I have quite a lot of trip data accumulated in TripIt, the travel tracking website - various itineraries and trips across the years. In case I either decide to close my account, or TripIt becomes unavailable for some reason, I'd like to back that data up.
In an ideal world, what I'd get out of TripIt is a PDF similar to the one I get when I print out an individual trip, but for all of the trips. However, I'm curious as to what other options there are - can I get accumulated calendar data for all of my trips instead, for example?
Note that I have 100s of trips, so any manual solution on a per-trip basis will not be practical. It would be a bonus if my backup mechanism could be easily automated or run from some kind of script.
I have a TripIt Pro account, in case it's relevant.
