Hi folks, I'm flying LX41 LAX - ZRH 7th september 2011 and plan to quote for an upgrade (Y -> C) with cash at check-in. Swiss tend to offer this on flights between USA and ZRH. My question is: will i earn EB points as in my original economy booking, or will i be able to earn EB points as in business? The reason I'm asking is that I have heard from others that it should work to get business earning in this case. However, when I upgraded with cash at check-in on a flight from BKK to HKG with Thai in 2009, EuroBonus retro registration would only credit me with points as in economy, see e-mail from SAS EB retro registration: "In the case of upgrade (TG628/10DEC) to another class, points are earned according to original booking class." and "Our partner has confirmed that TG 628 10Dec09 BKKHKG is not valid for accrual of EuroBonus points." Is it up to the airline (ie.Swiss, Thai..) to decide this, or is it EuroBonus' decision? Does anyone have experience with cash upgrades and Swiss from the U.S to ZRH?
