History taught me once verified, you'll get payment within 72 hours i.e. 3 days. That is purely my subjective experience though.
It is a real 'chicken and egg' scenario. AirBnB shun the responsibility onto your bank yet you have to wait a good 5 working (not calendar) days before you taken any action.
For the host, it is a silly process . AirBnB do not explain why it is so imperative to verify your account, thus why we are all downloading on a forum. When you setup Paypal and they request you verify your bank account, it takes max. a day to verify! Seems a little silly!
