untill waiting Sheikh Yerbootyreply,
i would add that i can also fly from
LH: BLQ (1 stop) to GVA for 65 Eur , but these are 2 separate flights....
so if the 1st flight delays, i will lost the 2nd flight! the only advantage in this case would be mileage earning and low price (+ LH network, but no connection guarantee between these 2 LH flights!)
