Travel at 80 shortly after a hip replacement is possible, but not easy, especially since we flew through the Frankfort airport. I prefer to carry-on my bag, but if I was flying through Frankfort again, I would check my suitcase. This airport required a great number of stairs and carrying the bag made it much harder.  The plane did not de-plane at a gate, instead buses met us in the middle of the grounds of the airport. Then we drove for about 10-minutes and we were dropped off at terminal B.  No signs, no staff to tell us where to go (right or left).  Luckily we turned right and soon saw a monitor telling us that our plane was leaving from terminal A.  We followed signs and got on a bus to go from terminal B to terminal A.  We then went through passport control and finally reached our gate.  Of-course we had to board another bus to go to the plane.  We boarded three buses to get from incoming flight to outgoing flight.
