indeed it utilize 346. About 3x per week. Cuz only 1 aircraft is utilized for HKG-YVR-JFK and back, so you can calculate the turnaround time.

Use any booking tools like the ones from www.flyaow.com/classcwt.htm and find for yourself which date is 346.

It MAY disappear because I see it used on HKG-SYD route sometime later in this year.

Additionally, the Y-class utilize the "new Y" seats. Personally I think such a huge TV (same as J-size) cause headache for Y-seat pitch of 32" (compare to 60" for J!!). I much prefer smaller size for Y-class.

There are 60 J seats on 346 which is handy to note. (ie. less chance of J->F upgrade but lots of Y->J upgrades)
