This is amazing, not least because of the huge U.S. military build-up on Guam.
I wonder if this means that Delta is eying a direct, non-stop flight to say Seattle or Los Angeles. Doesn't Delta have seasonal flights to Guam from other Japanese airports?
This really makes no sense because Delta has a strong base of customers in Guam. They even have a local Sky Miles credit card with a Guam bank.
