Hey, everyone.

I'm an experienced flyer, but haven't been on SQ metal in a few years. I'll be doing SFO-HKG-SIN and SIN-ICN-SFO later this year, and booked only because there's a reasonable chance at having WiFi en route. (UA offers WiFi on all 747s, so it's easy to "know" you'll have it. Unfortunately, it's also easy to "know" your service will be horrid, and your seat in J will be claustrophobic!)

I searched the thread extensively, but found nothing useful on WiFi availability.

1. Is there a thread on this? If so, please feel free to redirect me there.
2. Is there any account of WiFi rollout in the fleet? United, for all of its troubles, at least gives its passenger this guidance, which is very useful.
3. Anyone have personal experience on availability on 77Ws? I'm on 77Ws on all four legs.

Thank you!
