Maldives Challenge - Help?

My brother is planning his honeymoon in Feb in Upper and equivalent.

His route will be LHR - DELHI and then on to the Maldives and then back to LHR. LHR to Delhi is pretty straight forward, the problem is getting back from the Maldives to LHR in upper/business etc, preferably using Miles.

This is a bit of a challenge, so any help would be greatly appreciated.

Many thanks

If he wants VS Upper then Dubai would probably be the best return sector.
He'd need to buy a ticket on EK from Male to DXB though.
The only routing I can work out on miles would be with SQ??? (I think)
