Have to agree with the Green Nanner on this one. People will search for hours to save 50 cents on the fare, then spend like crazy the day of travel. Had 100 bags in the hold on a recent flight. That's $2000 additional revenue in one flight. Add in cocktails, a meal and a movie, internet connection to send Aunt Bee an email and the ticket price begins to look like the cover charge at a club.
I think WN is leaving $$ at the table, but Shhhhh, let's not tell 'em!
