The flr airdrop is already set in stone. No details have been given on who is participating in the second airdrop based on your FLR token. All I know is if the exchange is supporting both, then you will get to use 100% of the FLR to participate. If they don’t, you have to move it to one who will and you will only have 15% of the FLR available in time for the next air drop.
The snapshot was taken on participating platforms such as Kraken and coinbase already. So as long as you don’t close those accounts and you had XRP in those accounts when it was taken, you will get it.
