At the time, AA is not really another west coast airline. One of the main reasons that American bought Reno rather than expanding from within was to enable them to build a west coast presence without adding superfluous capacity in the region. Reno did alright, so I would expect that American should do well with the operation also. As they grow in the west, however, it will be a case of adding to an already crowded marketplace. I think that American learned their lesson during the AirCal takeover, and that they will think long and hard before adding capacity to this highly competitive environment. To be honest, I'm not sure how well AA will do on intra-California and CA-NV flights, only because they are by no means a low-cost carrier like WN or United Shuttle, so they can't as easily compete at the low prices that are found out west (WN for example often offers fares of $39 anywhere in CA). However, I think that their newfound west coast network will do a good job of feeding passengers to their strong transcon network, allowing passengers from throughout the west to take advantage of the Flagship Service flights that operate transcon.
