"Macbook Air activation code sent o dead iPhone, need alternative option: I got a new Macbook Air, when I tried to activate it, it asks for activation code send to other device which is my old iPhone, which was dead and unable to charge it up. Give me a solution where I can activate my Macbook without this activation code."

Getting Activation Code:
Contact Apple Support:
Ask the Apple Rep to assist with the log in over the phone. See fi they'll allow you to get the code elsewhere. Your goal here is to add a trusted device, as those are the devices that will get the code. So, have the Apple Rep allow anther device to get the code: About Trusted Phone Numbers and Trusted Devices for Apple Account - Apple Support
