When I arrived back in HK yesterday morning, my flight to Guam that night was cancelled 14 hours in advance, turning my half day in HK into another full day and night.
The initial auto rebooking had me flying the next day HKG-GUM-PVG-ORD-YYZ, inc. an overnight and half day in Shanghai (PVG) but arriving 28 hours later, which was briefly tempting but I opted instead to get myself rebooked onto HKG-ORD-YYZ the next day, which gets me in the same time as original 4 flight return itin HKG-GUM-HNL-EWR-YYZ.
I can still get my original frequent flyer miles credited since it was an involuntary change (it’s called Original Routing Credit). I just need to call United after the trip is over to get it corrected.
Added bonus: about 7 fewer hours in an airplane seat.
Back in the lounge this morning, looking a little scruffy…
