Booked ORD-SFO in economy with 1 companion (silver). I am platinum and we are #1, #2 on CPU list with 10/16 booked. We are seated together in economy+. There are no open 'rows' left in first, just single aisles or windows. How will UA handle the CPU's? Will we get skipped over if they release seats 1 at a time? What if they don't release seats 1 at a time, the seat map remains the same and therefore we cannot sit together? What will UA do then?
