Note that in your example, you nicely added to your original point:
"Virgin America has an entire fleet of brand new planes, comfortable seats, personal in-flight entertainment and wifi, and great staff."
Note that unlike other airlines, Virgin has tied together that correlation between price and value. Virgin is selling predictability. You pay more, and ALL of their flights are awesome (because they're a brand new airline? Only time will tell...)
