Connection time / risks of mis-connect in GUM?
Flying WAS-HKG on a Z fare, and found a crazy low Z fare (under $400) for the return leg HKG-GUM-NRT-IAD. As I've never been to GUM, I figured why not, except for the 50 minute connection time between the HKG and NRT flights. My concerns:
Do I clear US customs at GUM, or is there an international transit area?
Even without customs, is 50 minutes plausible, or are the odds of delay high enough to not chance it?
If I do mis-connect, how do loads tend to be in late January -- am I at risk of watching multiple days pass before I can get a seat out? And if that happens, how easy are hotels to find?
Given that HKG-GUM is a 737-800, and GUM-NRT is an old ghetto bird recliner 777-200, am I an idiot for subjecting myself to this?
