I have a question is there any way to do a connection in Frankfurt in an hour and a half considering that the first flight is on time and is arriving T-1?
I am planning a trip to Florence for August from Atlanta via Frankfurt with Lufthansa, i saw that there is a layover of an hour and a half and i would like to know if with this time i can going through security and inmigration and do not lose my next flight.
As you are flying on LH, your question is probably better answered in the LH forum. But, 90 mins is fine. Take a look at this thread
