Do not the SWUs say right on them they are good for LH metal flights on day of departure? And being a UA flight # ever earlier maybe?
HOWEVER ... just having taken 4 x 'Biz' LH flights intra Europe in the past week, (2 of them 3 hour flights) do not get too excited Bruce, as the LH 'Business Class' (sic) seats are 100% IDENTICAL to all coach seats! No amenity kits, no recline, no privacy ... 3 seats each side aisle etc.
A few days ago with several other FT'ers we flew FRA-DUS 'Biz' class where there were FOURTEEN rows of 6 wide 'Biz' class and only 7 rows of 100% identical coach sets!
