Why anyone flying today would depend on the Airline to provide food and entertainment is beyond me.
If I fly in Cattle Class I always take food and an MP3, computer, whatever as odds are the movie is some family crap without sex, violence and those naughty words... or the seat I have has the "Broken Unit"
As to the food, its probably so unhealthy that you could do better with a McWhopper. Take your own food and water, you will enjoy it more..........OR fly First Class
