Etihad sold me a ticket to travel to the United States from Abu Dhabi knowing there was a new ban put in place against the kind of visa i was traveling with. I had a layover in Frankfurt, Germany and wasn't able to arrive to my destination after being stopped in Germany. I had to purchase a extra flight to fly back home to Abu Dhabi which was an unnecessary extra expense. I would like to have my extra ticket i purchased refunded since Etihad should have told me I wasn't going to be able to fly before selling me the actual plane ticket.
