So my first instinct is to plead that I've done a search, couldn't find anything, please forgive me if...... Oh yeah - this is www.milepoint.com! Okay, I know a big advantage of the BA system is the ability to book one-way award tickets. Question is how that interfaces with two-for-one certificates? Will BA let me book 2 one way outbound and then simply convert it when the return opens up or do I have to wait for both directions to be available to be able to use the certificate? Hoping it's the former. Thanks.
