Hi , we are booked on a cruise out of Rome, finish in Barcelona, and while we’re in Europe would like to take in Krakow/ Auchwitz,looking at flights with Finnair, the question is , do we fly into Rome, Barcelona or Frankfurt, as Finnair fly to them all, I know it’s going to be a bit messy, but looking at suggestions ie fly into Rome then out From Barcelona to Krakow, OR flying in and out Frankfurt , using that as a base, hope this isn’t toooooo confusing, thank you in Advance
