Hi all, my wife and I are likely flying one of these planes red eye HNL-DEN in February. I have an Economy+ subscription so any economy seats are on the table. I've been considering the paired seat options (37A/B; 39A/B; 48A/B and 48K/L) but looking at the configurations, there's a chance we'll end up in a row of 3 for basically any of these options based on chance. Which paired seats have the highest chance of staying paired? I'm assuming the 48s.

I doubt I'll get much sleep regardless, but thoughts on these options would be appreciated - or if I should look somewhere else, like the bulkheads. Thanks!
