Most people are very cost conscious and go directly to the lowest price feature on most booking engines (travelocity, Orbitz, etc.) - the lowest priced carrier will show up at the top of the display. If it's Alaska's $73 fare, and not Virgin's $77 fare, it's likely Alaska will capture more of the business. Since Virgin is so new there will undoubtedly be some people that will be looking to try them out but when the dust settles, he who has the lowest price will almost always win the business - frills or not. The overwhelming majority of people want a cheap fare on a safe plane that leaves/arrives on time and don't care about mood lighting, meals or television - especially on a 2-3 hour flight.
