today i tried to get an upgrade for my next MUC-SFO trip on the LH SEN service line. in past it was enough to tell them my reservation code of the paid flight to get the upgrade (having more than enough upgrade coupons and miles ).

now they told me that i definitly need to tell my PIN to get this upgrade due to abuse of this service in past.

unfortunatly my pin is save at home where i'm only at the weekend. the woman at the phone line even denied to verify me by calling me back on my mobile phone, which number is stored in my LH profile.

anyone got the same experience? this is a big decrease in service of the usually excellent SEN service line .
