Even if we could, it would not have helped us. We were on the 767 and those dont have the extra comfort upgrades. What was really goofy is that they had the coach bulkhead row marked as premium and they were empty on both legs of our trip. At first they said they could be booked 24 hours out, but they wanted $50 per seat just to move up a couple rows...... not a big benefit for that cost.
I definitely noticed how uncomfortable the HA first seats are compared to US Air, AA, and United. Not much room and just not pleasant to sit in for 6 hours.
