Use British Airways Miles On The Ground

British Airways miles (Avios) can now be used to buy experiences on the ground.  There are dozens of tours, excursions, boat rides, and other fun activities you can do around London and pay for with miles.  Denver is less lucky and only has airport transfers available.  These could be good value too at 1-2c a mile in the few I priced out in cash.  Even better, there are no fuel surcharges or UK air duty taxes to pay on these redemptions (taxes and fees turn a free round trip to London into a $400+ trip).  Avios can also be used for car rentals and hotels, but that isn’t terribly noteworthy.
