Can I bid upgrade on SWISS for ticket booked thru United
Hello,
I booked ORD-Zurich on Swiss Airline thru United booking. I am trying to use Bid Option on Swiss Airline website to upclass to Business Class but the option is grayed out. Called Swiss and they suggested to call United as booking is done thru United. Called United and they suggested to contact Swiss. Looks like I am stuck in between. Any advise to navigate thru these red tapes. Thanks A
