Hi,

about to book a multi-city fare with a RT of SEA-HKG as part of it.

Was wondering if others here experienced this route for a comp upgrade. I am a GM and many times get upgraded on other intl flights which are often oversold. That said, I am unsure how full these flights get. West coasters have other choices other than SEA (LAX, SF for starters) so I assume it's not a big choice for connecting travelers. But, I dont know much. What are the chances for the flight to be fulll/oversold and business class seats given to medallions?

Any help on when to book in the week for this to happen will be appreciated as well. (I am pretty flexible with the dates)

thanks!
