Very confused about exit rows
Ive called 6 different times to Virgin America and gotten six different answers. If one books the cheapest ticket, what is the charge to upgrade to an exit row. Not necessarily the Main Cabin Select rows, but just an exit row. I know it depends on length of flight, but would the cheapest option be for the shortest flight?
Also can you upgrade to Main Cabin Select from the cheapest Main Cabin fare for a nominal fee (under $100?) on day of departure?
