Ha ha ha. Let me guess, total ticket price was £1386.61? Sounds like an excellent deal to me
The VS mileage redemption system isn't very complicated is it, there's a clear pattern equating 3000 miles to an £18 redemption value and it increases in stages until the left hand column runs out of miles to take from your account or the right hand column gets to the ticket price.
How much does it cost to buy 3000 miles these days?
