Sorry for being unclear. I am not concerned about miles. I book and paid an F partner ticket for myself and spouse. Due to an emgergency, spouse is home already (on a different airline). So I need to fly back alone. A call to EK revealed that I cannot fly alone but only with the spouse. If I check-in without spouse I have to buy a new oneway F ticket just for me, the partner tickets will then be voided. Can this be true?
Just check in online, and the say your partner is arriving later if they ask when you check your bag.
Once on the plane, tell the Purser that your partner is stuck, and will not be able to make the flight. This should mean the flight is not delayed.
