FRA connection, walk/ride?
Nov. 28...
Will be arriving FRA via UAL at gate "A20"..but looks like must connect with Lufhansa at gate "B6". Should/can elderly walk or "Sky Train" to the LH gate?
Would there be Passport control, Security, or Lounges on the way?
Have carry on. Think we will need boarding passes.. Recall having difficulty in FRA and with LH many years ago. Could not upgrade the LH flite.
