There is a fuel surcharge of $450 per direction, except for Infants.
You can only have a stopover in the listed cities on the AC Fare.
The LX Fare allows a stopover anywhere on the routing.
Thank you, for your response.
I thought of another question, regarding the fare rules for AC, LX, or other airlines.
Let say I buy a ticket issued by AC. That means that at least one of the 2 transatlantic flights have to be designated as an AC flight on AC metal or codeshared on the other Star Alliance partners mentioned (TK is not one of them), or does it have to be both transatlantic flights (one in each direction) have to be designated by an AC flight number (ie AC metal or AC codeshared).
In this scenario, I could fly either directly to LHR or FRA on AC (in at least one direction) from/to YOW, but not in the other direction, and not on any any additional AC flights when flying intra-European flights or Europe/IST to DXB flights. So the itinerary can legally, by what is mentioned in the fare and routing rules, just include one transatlantic AC flight for the whole itinerary?
