You can nominate for your Crunch credits to be transferred to your Velocity account automatically. Simply log in to your Crunch account here, then go to the Account page and choose the Velocity tab.
If you have not yet linked your Velocity Frequent Flyer Account you will need to do that first, using your Velocity Frequent Flyer Number.
Then, under Auto-transfer, select "Yes" to have your full balance of Crunch credits transferred to Velocity Points on the 1st of every month.
