19. (1998) Not counting international flights, what is the longest commercial flight out of Colorado? We’re looking for the route, the airline and the aircraft type.

Per teddybear99: Sorry, didn't see that guess and your qualifier. When I mean dubious, there are questions in the past that have said domestic that went to US Territories outside the Continental US. Now the question in hand is asking for the one single commercial flight from Denver and as Boston and Miami are long distances, they are both served out of Denver by multiple airlines, so they both would be a no go. I am going to guess United Airlines to Portland, ME on a DC9-30.

Now look what you've gone and done - you done got jrl767 all fired up!

Per jrl767: WOW!
(1) UA never operated any DC-9 series
(2) PWM-DEN is 1782 miles per gcmap, and there’s NO WAY that a D9S could make that as a revenue flight without serious payload limits (range by itself isn’t an issue; I caught a Space-Available hop on a Navy C-9B that went NAS Alameda to NAS Norfolk with a total of 14 on board)







Well that's not necessarily a bad thing. It's good to get fired up now and again! That said, keep in mind that the question addresses flights out of Colorado - not just Denver. The OAG I referenced was from January 1998.

Awright, boys! Go get 'em!!
