Hi all,

I have a trip coming up late this year: BOS-HNL-OGG-PHL

I used points to get two business class tickets BOS-EWR-HNL, and now I need to buy cheap tickets to get back. United one-way tickets from Hawaii are pretty expensive, but...

...we also have a trip this year PHL-SFO-PHL.

So, now, if I buy an open jaw round trip: PHL-SFO-OGG-PHL, I can get that for cheap, and then all I need is a cheap one-way SFO-PHL.

My question is: is this legal? Or, rather, is this back-to-back ticketing? Note that I'm not doing this to get around minimum stay requirements (we'll meet all the minimum stay requirements easily).

I do have a backup plan: flying AS from Hawaii to west coast, because they have cheap one-way tickets.

Thanks.
