Of Charles de gaulle
After missing the Paris Helsinki flight:
"Here's your new ticket. But you will have to go out and re-check in again. I can't give you the boarding card as the other flight is using a different system." And also: "Tell them about your luggage when you check in so it will be with you on the same flight".
