Alaska Mileage Plan is now offering one way awards at half the mileage of a roundtrip. This even applies to ‘award sale’ destinations, e.g. one-way San Francisco to Puerta Vallarta currently runs 7500 miles (subject to award space availability).
This also means that “split awards” are now possible — used to be that award space needed to be open in both directions to get an award at the standard mileage price, if it was unavailable one-way you’d need to book at double the miles. Now you just book two one-ways, one at the standard price and one at the higher rule-buster price, in order to do a split award. (Their technology doesn’t seem to automate the pricing and you do need to do two separate awards if you want this option.).
As always, more choices (that don’t foretell future devaluations) are always welcome. Kudos Alaska!
