Horus Pay, an EOS Block Producer, has put together an easy to use Airdrop Calculator that shows you the anticipated quantity of upcoming airdrops for your EOS wallet based on your EOS Public Key (Not your private key) and the genesis snapshot. This obviously might not work for a new wallet and may be off if you've transferred tokens in/out of your wallet since the launch of the main net.

There are also a few upcoming airdrops that require you to register in some form or fashion. I've listed them below in case you don't want to miss out on those and you hold your private keys for EOS. I'm not a huge fan of having to "register" to get airdrops as it is basically linking your account to an email address or whatever personal information that they are requesting. But if you don't want to miss out, they are forcing your hand.
