Flighty is one of my very favorite apps. It’s exceptionally well-designed and extremely useful. They just pushed some big UX updates, including this cool year-end passport, which I thought was nice. I had many years of travel data in TripIt, which I was able to import. Cannot recommend this app enough. Because I travel somewhat infrequently, I just pay the monthly subscription before my flight and then deactivate it after travel is complete. Nice to have that as an option.
