Apple says this:

"Tip: Though you can transfer data wirelessly by connecting both computers to the same Wi-Fi network, it's often faster transferring when you directly connect your MacBook Air with your previous Mac using a Thunderbolt or Ethernet cable."

I don't own any Thunderbolt cables (yet!), and of course the old Air (2012) doesn't have any Ethernet socket. So, what cable do I get for this?
