I booked a flight for 2 from O'Hara to Florence thru Swiss International Airlines. Originally I booked premium economy on flights operated by Swiss air. A few days later I was informed that the flights from O'Hare to Zurich and from Zurich to O'Hara were changed to flights operated by United Airlines. I decided to upgrade to polaris business on these flights. I was able to upgrade on the United Airlines site the flight from O'Hara to Zurich. I was unable to upgrade on the United site from Zurich to O'Hare. It kept giving me an error code. I called United and they told me only Swiss could upgrade me. I called Swiss and they told me only United could upgrade us. I'm paying with a credit card, not points and there are many open seats. The availability of business polaris seats was confirmed by both Swiss and United. This is our 52nd wedding anniversary and I know I should have booked business from the start however at the time i thought it was too expensive. Then I realized that this may be the last trip we take and we have always flown economy. Anyone have any ideas or experience with code share flights? I have talked to "supervisors" from both Swiss and United and they are "very sorry". Any help gratefully accepted.

As they have changed the carrier from the one you originally reserved, you could try to find out if you can cancel for a full refund, and then book in the class you want.

Frankly, Scarlett, they don't give a damn. (Sorry, couldn't resist.)
