So on either 9th/10th November I had wanted to either:

- fly LHR to San Francisco one way (business) and the return from Boston on 22nd to LHR (business)

- OR fly LHR to Boston on 9th November and either return from Boston on 22nd or fly from San Fran on 22nd to LHR.

Basically, I’m wanting to fly business as cheap as possible and that’s what’s fuelling the either/or. Ideally I would fly to Boston first, and then return from San Fran.

Anyway, I have 90,000 avios and I see on reward flights I can fly one way to San Fran business class, for 90,000 avios plus £238. Would that be a waste to take that for just one leg? Unsure of what’s good value.

Thank you if anyone has any advice.
