Mint.com is convenient to have an overview of one's bank/brokerage/retirement accounts. Is there any similar website for frequent flyer miles?
1One thing I would note is that unless you fly a lot splitting your miles between a bunch of different programs will make them much more difficult to use, since you can't combine miles between different programs (even within an alliance) for a particular redemption (at least not without going through a points broker and losing a lot of value in the process.)– reirabApr 2, 2018 at 4:19
AwardWallet is fantastic and very conceptually similar to Mint.com.– Ivan XApr 22, 2018 at 15:47
I'm familiar with AwardWallet, which has both free and paid options, though I've never personally used it. As with Mint, you have to trust them with your data and account information, and there are some limitations, such as United, Delta, and Southwest not allowing them to access accounts (though you can forward your statements in for importing).
TripIt has a points tracker as part of its paid TripIt Pro service.
points.com is another option in this space.
