I have a few flights with LH in early Jan 2017-
HKG-MUC: PE to C, fare class N: bid range: USD690 to 1190
MUC-TXL: Eco to C, fare class Y: bid range: USD50 to 170
TXL-FRA: Eco to C, fare class Y: bid range: USD50 to 170
For HKG-MUC, I am planning to bid min USD690. Expertflyer seat map shows 26 (out of 56) empty C seats (not a meaningful indication I know). Any advice?
