I needed to book a ticket from Sapporo CTS to Tokyo HND one way on specifically Japan Airlines. I wanted to see which program would cost the least for an award ticket.
Asia Miles won’t even allow a one-way ticket with JL, so it would cost 15,000 roundtrip.
American Airlines charges 7,500 AAdvantage miles, not too bad.
United charges 6,000 miles one way, but they partner with ANA, so no good there.
Lastly, I remembered I had these unused British Airways Avios and they only cost 4,500 miles, plus $2.06 USD in taxes/fees. This was the winner!
But one of the side benefits of using the BA Avios was that I can keep my miles from expiring. As long as you earn/redeem Avois once every three years, the expiration date gets pushed back, so this was a good way to keep my Avois active since the expiration was coming up in 2013. So my suggestion is if you’re looking for a short flight sometime, not only are BA Avios a cheap redemption, you can keep your other miles active by doing so.
In case you’re wondering, I needed JL because I was continuing on a Cathay Pacific flight from HND to HKG so I wanted to make sure they can interline and my friend was on the same two flights.
