Thank you. I was not sure if this rule was just for miles upgrade. Im interested is the last minute money upgrade. I thought maybe paid upgrades could be offered. So the only way to travel business in this segment would be change my flight in swiss I guess. Actually my main problem is the luga...

I have a doubt I booked a swiss flight and my return is a code share flight operated by singapore with a flight number of swiss LX. So I will have to check in with singapore airlines. The paid upgrade at check in is going to be available/offered for my singapore flight with a swiss flight number?
