We will be traveling through the Frankfort on our way to Milan for our Bellissima trip this week. I have been researching what to expect regarding security. I am puzzled by these instructions. "You can take your carry-on luggage into the cabin. Please only bring one piece of carry-on luggage for inspection" It does not say you can only have one carry-on. So does mean they will only examine one of your carry-ons?
