My Fitbit reports the number of flights climbed - it's the Fitbit 'One' model. Along with my daily 10k steps, I have a flights climbed goal that I track through the website. Maybe it's a different model that doesn't track this?

It was removed after the One (on the Flex), supposedly because it didn't work that well. I imagine it would have been hard to waterproof as well.
