Hi Sabina,
Read the following steps and see if you can make changes accordingly:
1.Change the listing currency of your India listing to INR from your manage listing page (to get to this, log in, click on Host, click on Manage Pricing and Calendar for the listing, and go to Pricing - change to INR and make sure it saves)
2.Add a new India-based payout method to your account (go to Account Settings, Payout Preferences, Add Payout Method and choose India as the country)
Note: Do not forget to make the new bank account details as your default payment method.
Once you reconfigure your account, you can see options written next to the details.Click on the options and drop down menu will come > select Make as default.
Now since you have 2 bank accounts you'll have to make any one of them as default. And if you want to split the income in both. Further follow these steps:
Go to Payout Preferences on airbnb.com
Under Payout Routing Rules click Add Payout Routing Rule and direct your India payouts to your INR payout method
Hope it helps!
