I'm going in 2.5 weeks ... have seat 2F the whole way. I don't really feel like calling UA to split out the segments, as right now it's sold as HNL-GUM direct. I'll probably get bored with 14 hours in the same seat more than I care about which island has better views, but whatevs.
Really sad I can't make the FT DO in October as I had already booked this before they started planning the DO! oh well.
