New Routes

Why would they add BNA -> SFO when they already fly BNA -> OAK and UA has daily BNA -> SFO?

All new routes:

• Colorado Springs (COS) to Cancun (CUN) • Baltimore (BWI) to San Francisco (SFO) • BWI to Ontario (ONT) • BWI to San Jose (SJC) • BWI to Long Beach (LGB) • BWI to Portland (PDX) • Seattle (SEA) to Houston (HOU) • Nashville (BNA) to San Francisco (SFO)
