Had me confused there for a second referring to DEN as DIA, not that it’s wrong but at first I thought maybe F9 was somewhere else before DenverI enjoyed it when I was there of course F9 wasn't an LCC. F9 basically had the whole A concourse at DIA. Of course that was many years ago. I know at least 3 people are still there when I was there. You can live reasonably well if you opt to live away from the city. Also now that they put a rail line out to DIA, with a stop fairly close to the company. Im guessing a 25 min walk, obvious less if you take a bike.
