Bittrex to sure would be the most likely. I asked in their slack and they are not sure yet. But they already support Omisego. So it would make sense that they would support the airdrop. But this was announced very quickly. If they don't support it would be from lack of time. I would be VERY surprised if Coinbase even acknowledges this. Unlike a fork where two coins are produced, airdrops happen more frequently and I don't think they have the time or resources to address it. Just a guess though. Other exchanges may. I listed those as I use bittrex for most everything I can. Not sure which wallets but any that support Eth and smart contracts should. Myetherwallet, Jaxx etc.

I've tried finding info on how air drops work but cannot find a technical explanation. Do they function the same way as a fork where if where you have the coin supports it they automatically create a wallet with your airdropped tokens? or if I have the ETH in a wallet like Jaxx with my private key I can access it? Thanks!

no fork involved they use a smart contract I believe to send the token to ether holders. So Jaxx should be fine. Nano S, myetherwallet etc. It's up to each exchange if they will participate and give rewards. This is my understanding.
