We will be flying from Charlotte, NC to Vienna, Austria with a layover at LHR in December.
We have an option of a 2 hr layover & a 3 hr layover.
We have never been to this airport - we usually transfer thru AMS or CDG.
Would 2hrs be enough, or would you choose the 3hr?
This will be AA from CLT to LHR and then British Airways from LHR to VIE.
This is one ticket booked MultiCity as we are flying back home from Munich.
Thank You
