Why did United Airlines terminate their Chicago - Honalulu route? This service ended when the DC-10s were retired. So, why not operate a 777 or 767-300? There seems to be allot of traffic between Chicago and Honalulu. I was on UA flight from ORD to SFO and almost the entire plane was continuing on to Honalulu. Why didn't they resume the non-stop service? ORD-HNL used to be United's signature flight, back when it was good ol' flight 1.
