XONEx and UK stopovers
I am booking an DONE4 starting in either AMM or CPT with 2/3 connections via London, hopefully ticketed with AA.
With the high charges for UK departures it makes a big difference whether this is ticketed as connections or stopovers. Can anyone advise what would happen if I ticket originally as connections then date change after ticket issue to be stopovers? Would AA need to take the extra tax/APD at time of date change?
