Just wanted to pass some interesting info though as always take it with a grain of salt. OIAA set up a plane spotter Facebook page were people post pictures of planes arriving or departing ONT. Most of the members including myself are plane spotters or actual workers at ONT(loaders, ramp agents etc).

One of the ramp agents who serviced the 77W and now the A350 posted a photo of the A350 as the cater's loaded it. A new member asked why did CI change the flight to night time since they wanted to fly to Manilla from ONT to avoid the LAX clusterf$%^, though didn't due to long the layover in TPE, and flew PAL instead. Since the ramp agent was busy, I answered the question for him with what we know (daytime loads, connections to greater Asia). Now, with the short layover, they're going to try and take the flight. The ramp agent later on responded to him agreeing with the points I stated.

Though, the ramp agent gave us a tidbit on what CI and OIAA are expecting of this route. He didn't delve into specifics since OIAA authority is overlooking the page, though was at liberty to say that both parties are striving for a 100% load factor, though see 80% or more load factor as a win for both parties. So, take this information as you see fit.
