Late Avis pick up on BAH booking
Just had a change in time of some AA flights that we are on separate bookings to our BA holiday flights and car rental.
We have an Avis car hire as per of the booking with a pick up from MIA scheduled for 6am but now we won’t be arriving in MIA until noon.
Do I need to let anyone know or will be be OK to collect my car 6h later than they are expecting us to ?
