Mostly because I dislike and prefer not to use Google. It's also just nice to not co-mingle accounts in that way for something this specific. I have an app I use exclusively for holding my flight information for any flights I take. I don't use it a lot, but it's nice to know that I have one single app to look in for flight info. If I'd unified all my eventing around Google Cal or such, then yea, I could probably just use that, but I didn't, so having a few purpose-built apps is nice.
