This check & msg.send are duplicated in each of the commands. I'd suggest moving it to a helper like validEnvironment like:

validEnvironment = (msg) ->

   if process.env.HUBOT_AIRTIME_URL
     true
   else
      msg.send "Please set the HUBOT_AIRTIME_URL environment variable."
      false

That would simplify the other commands to like: return unless validEnvironment(msg).

I would also include more details about how you figure out what value to put into this variable. Do you sign up for something? Have to setup software somewhere?
