"PAL is now not planning to launch any longer US routes. The airline was earlier considering Miami-Manila, which is approximately 8,100nm. However, PAL is now instead only considering Chicago and Seattle for its final two A350s, which are slated for delivery in 2019. Chicago-Manila is slightly shorter than New York-Manila."
(contradicts themselves but I have heard this from another source also)

I remember them coming to ORD back in the early 1990's with a 747 with many stops in between. This would be a nonstop with the A350-900ULR wich has a range of 9700NM and 280 ton payload if that is approved, although I think the payload will be less at max distance.
