I've had the UA cheeseburger domestically. It was actually surprisingly good for what it is. Not setting the world on fire, but it is defiantly a good classic American cheeseburger. Would have it again for sure. 

I'm pretty sure United is also upgrading the Melbourne-San Francisco service from a Dreamliner to a 777. So even more capacity for them on that route as well. Great to have a solid challenger to the Roo.

UA have confirmed the return of a 3 step meal service and revamped meals for all Polaris long haul services from June 1. I'm willing to hold off judgement until then. So fingers crossed. Much prefer Polaris trans-pac compared to QF, plus UA onward connections.
