Baby and milk

Currently i ebf my 11 month old. In 2 months we are going on a 2 week vacation. Im trying to switch over to bottle feeding, i have some stored breast milk. I dont know what im going to do when we are on vacation. We are going out of the country and I dont know if I should be taking 2 weeks worth of frozen breast milk with me?if yes, how do i take it on the plane and how do i store it? I dont prefer to breast feed in public so thats why im trying to get her used to the bottle. But i still dont know how im going to make this work.
