Haven't noticed this mentioned yet since the HBO seat selection rules were put in place.

I've booked two domestic reward tickets and have selected the front row by virtue of being a GCH.

A friend of ours is now booking an HBO fare to join us on the trip up, so the questions, in order, would be:

1) Can I do a 'To Complete Party' and put him on Row 1 with us for free?

if not:
2) Can I do a 'To Complete Party' and put him on Row 1 with us providing we pay a 'seat selection fee' because he's HBO?

if not:
3) Can I do a 'To Complete Party' and put us together somewhere else on the aircraft?

I know this can be answered with a phonecall but it's useful to be armed with other people's experience, and I'm assuming more people will want to know the answer to this at some point.

Thanks.
