It is a single-sector high-TP flight as the intermediate stop does not count for these metrics.
PHX is not on the transcon list. FWIW, neither are SMF, PSP or RNO, all of which from time to time have single-numbered service to or from the east coast.
Care must be taken with these single-number stopping flights. They come and they go, and are often asymmetrical; e.g. you'll see SMF-BOS but not BOS-SMF. For example, at the moment AA lists LGA-PSP, but not PSP-LGA.
