Hey there knowledgeable people all, So next summer I want to travel to Japan with my wife, using United to travel on ANA. A lot of flights show 1 first class seat available (on United.com) on the Trans-pacific leg, but not the two I need. So my question is this: since I'm booking out of our respective accounts and we can't be on one PNR anyway, should I book one of us in first class and the other in business, then hope for another seat to open up and change the business class seat to first? Is that easy to do? Or should I book us both in business class? Appreciate any pointers -- I've only reserved award travel on Delta and they don't have crazy things like "first class partner bookings"
