Good news about the landside transfer; of course, there's no reason why you can't either end the Avios ticket in LHR and travel on a separate booking or, even better in terms of access rules, change it to terminate in e.g., NCE (unless that's a dealbreaker for a 2-4-1 perhaps?) This would leave you with INV-LHR| possible stopover | LHR-CPT | main trip |CPT-LHR-NCE all on one ticket.
I didn't know that the ticket price would be recalculated - thanks for the info. When we've done this in the past it's been from Edinburgh, so the air passenger duty has already been calculated ad included in the ticket price.
Thanks for the suggestion to change the final destination from INV to somewhere like NCE - but a 241 redemption has to start and end in the UK. If we cancelled the LHR - INV leg would this still be within the redemption rules? .
