I've been baffled as to why there are not non-stops from Denver to Reno, Cincinnati, and Memphis included in Frontier's network.

Cincinnati/Memphis- both served by United and Delta, both have seen large capacity cuts as prior Delta/Northwest hubs, and could attract passengers connecting to the west coast.

Reno- Served by Southworst and United but seems like it could at least handle additional seasonal service on an E-Jet.

Maybe I am missing something, but what are your thoughts about these destinations?

Memphis - F9 made the attempt to go there including some flights to LAS and NW pounded them for it.

CVG - DL will pound them like do anyone who enters that market against them. Besides F9 flies to DAY which covers most of the Cincinnati market.

Okay, CVG makes since, but I still see Memphis as a valuable spoke to Frontier. There is room in the market for not only origin-destination flyers but connecting passengers as delta has announced cut backs in Memphis.

"The airline (Delta) announced Tuesday it would reduce the number of flights from Memphis by 25 percent, dropping its daily flights from about 200 this summer to 150-170 by the end of the year." Memphis Business Journal

Frontier has served both Memphis and Reno in the past.

As mentioned by another poster, the Memphis experiment turned out badly. Frontier went in with flights to DEN, LAS, MCO, and FLL. Both Northwest and AirTran pounced, adding flights and capacity. I doubt you'll see Frontier return to this market anytime soon.

Reno was cut a few years ago. Loads and yields were never that great.

Cincinnati has the potential to be a decent market from Denver but Delta would likely retaliate. When Frontier announced MCI-MSP earlier this year, Delta responded by adding MCI-BOS/CMH/MSY/AUS/LAX and OMA-DCA. There's no telling what they'd do if Frontier went into another one of their hubs.

I'm not saying Frontier has to go into Memphis and add all kind of capacity to non hub cities, just 2x or 3x daily on an E/190 to Denver.

Memphis lacks non-stop service to the west coast, Examples include SFO, BOI, PDX, ABQ, SAN, SNA, TUS, GEG, SMF, and SBA. All of which Frontier provides connections to through Denver.

I don't see why this isn't enough connecting traffic, in addition to O&D traffic to keep Frontier afloat on this route.

Two or three daily on E/190s is actually a lot more capacity than UA puts on MEM-DEN (2 x ER4), and UA has a far larger connecting network from DEN. DL is 2x CR9.

Have you dug into BTS (or other) data to see O&D passenger counts MEM-ABQ/GEG/SBA?

As for DL cutbacks in CVG and MEM, both cities are still overserved for their size. CVG ranks 58th in domestic origin passenger counts, right with Omaha (57) and Manchester, NH (59). MEM is even smaller at 64th, with OKC (63) and Louisville (65). Yet this is what Delta offers:

CVG 146 peak daily departures to 56 destinations

MEM 197 daily departures to 73 destinations

MKE ranks 42nd in domestic O&D passenger counts. What frequency and destination count does F9 offer from MKE for comparison?
