How do I transfer my Sacramento Kings tickets from my Apple wallet to another iPhone?

If the ticket issuer permits it, a transfer may done by following the steps in the Apple Support article I posted below.

Add, use, and share boarding passes, tickets, and other passes in Apple Wallet - Apple Support

Some issuers require the tickets be transferred back to your online account and then shared to another account. Additional support is available from the issuer of the tickets.

You can only transfer directly if supported by the ticket broker. Otherwise, you need to use the broker's website or method to send the tickets.
