The 50 minutes is the usual for one of the main Continental flights. I was worried as well, BUT everyone said not to worry...the smaller flight always waits for the inbound because almost all their passengers are coming from the Guam inbound.
I have done that one five times in the past few years and it was true what they said.....of course I would feel bad if you did it and missed.
I felt that the worst case senario was acceptable to me....you could ask what the next flight would be?
I would pick up the Continental from Newark, Houston or LA...to Guam.
Air Micronesia (Continental), "Air Mike" Guam to Koror.
You'll love the Blue Corner action!
For us, I try and use mileage for the Guam-Koror portion as it is almost as much as the LA to Guam portion. (More efficient to use mileage than cash for that portion)...I had it figured out at one time, cash was better for the leg to Guam.
Once I got on the plane that stopped everywhere...still not sure how that happened, but there is a flight that lands all night long various islands.
