What happens when you chat with friendly flight attendants in the galley? If you're lucky, you learn about future route development plans. The very sweet flight attendants on my Virgin America flight from JFK to San Francisco last night told me that Miami, Boston, and Chicago are all on deck, and that Honolulu and various destinations south of the border are also in development. The flight attendant said "South America"! As in BA? Lima? Santiago? My imagination is running wild. (Or was "South America" mistaken shorthand for Mexico? In any case, I'll be waiting for more information.) And sure, I could have Googled such plans, but somehow when information comes from actual employees it is more compelling.
Plus, one more time: friendly flight attendants. Doesn't it seem like a long time since you encountered genuinely friendly flight attendants on a domestic US flight?
