We are planning a trip from the US to St Petersburg,Russia and then we want to fly from there to Prague, Czeck Republic and a few days later to Bruges,Belgium. We plan to take the train to Paris,France and fly back to the States from there, so we are interested in inter-european airlines- not a multi-city ticket from the US. So far, I have only found Czeck Airlines. - We want safe and cheap! Also, can we get our airline tickets while we are traveling or should we make our reservations in advance?
