who ever booked the airline reservations for the return flight should be fired, we had only one hour between the arrival of our flight from Dubrovnik on air croatia and the departure of our American flight from Frankfort to philadelphia, when we landed in frank ford, we were told one hour is never enough to make a connection in the Frankfort airport, the airline people put us on a lufthansa flight which left serval hour later so naturally we all missed our flight from Philadelphia to chicago, of course we know smart tours was not responsible for that flight, but smart tours was totally incompetent in serving up an itinerary to allow only one hour between flights in frankfort. a terrible ending for a nice trip
