On Wednesday, the first Virgin America Airbus A320s will take flight from New York (JFK) to Los Angeles (LAX) and San Francisco (SFO). The offshoot of European giant Virgin Atlantic, VA is owned primarily by Black Canyon Capital and Cyrus Capital Partners. It enters the market promising to deliver better prices and service than its rivals.

Its immediate rivals would appear to be JetBlue (NASDAQ:JBLU) and Southwest Airlines NYSE:LUV), both airlines operating on a model established by Virgin Atlantic focused on price, price, and price. How likely is Virgin America to make an impact on the increasingly crowded and fragile American air industry?

It has already driven down the price of the NYC-SF route to $250, according to the Wall Street Journal, significantly undercutting its rivals. How much of this price reflects lower costs, versus acceptable losses to establish business, is not clear. The airlines does start with new planes and hardware and new (cheap) hires, so it likely is starting with the lowest overhead it can anticipate.

JetBlue and Southwest, on the other hand, are already struggling with the increased expense of maintaining well-used equipment and the growing salary expectations of experienced crews, leaving them less room to trim costs.
