Same here on BOS. To the west, there are plenty of large unserved places to be added like Portland, San Diego, Sacramento, Salt Lake, etc. On the Midwest side, those are currently served with their existing code share via MSP, however.
I would be very surprised if most of these larger destinations (on both sides) are not added in the next wave or two of additions. Perhaps they wanted to get through the initial teething period with some of the potentially-highest-volume ones running. Most of the via-Denver markets Midwest is getting in round one are small, and most of the via-Milwaukee markets Frontier is getting in round one are cities they already serve nonstop. There will be some traffic going both directions in this round, but in lesser numbers than routes like DEN-BOS and MKE-SAN could generate.
