I always have great respect for the insight of
fastair and you.

However, I have requested and received partial refund for refundable tickets. I only got like 20% back and was told that:
Refund = Fare Paid - Fare for Flown Segment(s) - Fee
My understanding was that it was refared as one way with excess credit refunded. One way fare was about 80% of round trip in my case.
I would love to know if this is correct or if there is a difference formula.

Note: it was an international close-to-full fare ticket.

Why do a throwaway segment when one way fare is lower than round trip?

In this example, refund of partial used round trip is $1700 -$1000 - fee. You are no better off than buying one way in the first place.
