Hi,
I was looking for easiest way to get silver and then gold on same day trips
I found these routes
booked to get silver
LUX-
FRA-SKG-MUC-FRA-LUX where FRA-SKG-MUC is with A3 so 2 legs and get 10500 tier miles, so silver should be fine
I also try to get gold with only 1 trip
eg
LUX-
FRA-ATH-SKG/HER-ATH-FRA-LUX
or
LUX-FRA-
MUC-ATH-SKG/HER-ATH-MUC/FRA-LUX
but really difficult to find, only with 1 night in HER/SKG or ATH
I was also looking for SD 4 legs, but is very difficult to find ones
X-ATH-SKG/HER-ATH-X
cheers
