Hello everyone I’m a bit of a rookie in the points game I’m surprised I have pulled this off, but I have a few lingering questions that I’m not getting clear answers on.

Itinerary booked Saturday 2/17 7AM Pacific 2 Hour hold time

Itinerary:
115k + $680 fees each
ORD-LHR (B)
LHR-ATH
ATH-IST (B)
IST-ADD (B)
ADD-NRT (B)
HND-SFO

I’m a couple of weeks away from the trip, so here are my questions.

1. What are the chances of the getting 2 business class opening up on HND-SFO?
2. What is the luggage policy? Is it 70lbs 2 pieces for business? Or since I have some economy legs, would it be 50lbs max.
3. This is a stretch, but is it possible to get multi-city checked bags? I don’t need my checked bags until Istanbul and I don’t want to take them from airport to city to airport again. Anyone have solution for this?
