I should note that I have used various ways to track my travels.
I started with an Excel spreadsheet, which I also used to track and plan earning and retaining status with airlines.
Then I used openflights, both the version which used to be part of this forum, and, subsequently, the original site.
And as I have previously observed, I used TripCase for my upcoming trips.
I have also stored my flight data in FlightRadar24, Flighty, Flights25 and a few other apps/sites I can't immediately recall.
However, TripWaffle is the first app/site which has provoked me to try to upload everything: flights, accommodation, trains, car hire, ferries and so on.
