The first class section to me is really a business class level of comfort. On a 5-hour flight, it's worth the upgrade still. With chronic back issues, I appreciated the legroom. I was in 6H. The USB ports weren't working to charge my phone but I had a Anker charger on me. They provide iPads for entertainment. The movie selections weren't great and I wasn't interested in re-watching TV shows.
The foot rest was at uncomfortable height but it wasn't until the return flight that I realized that they are actually adjustable! You have to push it all the way down first and then adjust it to the height you desire. That made them a little more useful since I'm of shorter stature. The seat recline was not impressive.
I didn't bother with breakfast on the flight to Oahu but the lunch on the return trip was good - curry cauliflower. The flight crew/staff were nice and I have no complaints about that.
These seats made the flight to and from Hawaii tolerable. I hate LAX and am willing to book these seats on this route again on my next trip to paradise.
