I've done the ANA search for a one-way flight:

MAN-FRA-INN in Y

Am I correct in calculating that this will cost me 8,250 miles for a redemption booking?

Z1-Z1 = 9,000
Connecting flight in Z1 or Z2 = 7,500
Total 16,500
Miles needed for one way trip = 8,250

Or have I got this totally wrong?

Cheers,

Andy
