My own opinion, Chrome is a useless OS when it comes to development, especially considering you can go to Target, Macy's or Walmart and grab a Windows based 'basic' laptop for roughly the same price as a Chromebook that will do what you need it to.
HP has a basic starter setup for under $250 right now at Walmart, its not pretty but, you should in theory be able to do what you need without worrying about Chrome compatibility.

As I say, just my opinion but if its just for travel, I don't see why you would want to spend extra time and effort worrying about an OS.
