We have 2 business tickets to BKK. From NRT-BKK I was only able to get one seat in Y and one in J on NH. Then UA screwed up and lost my Y seat on NH. They replaced it with J on UA since NH was not avialable.

So now I have 2 J seats on 2 planes at roughly the same. Now the Y seat is available on NH. My fiancee informs me that she will be very not happy if we are on 2 planes as this is our honeymoon. I have not changed from UA J to NH Y because I figure my chances of getting a 2nd J seat are twice as much if I keep them split for now.

Flight is not unitl Dec. 19. Which is more likely to happen? A 2nd J seat opens up on UA or all Y seats disappear on NH.
