About the only use for such a small amount of miles is to purchase internet but 1,0xx miles is probably not enough for even the shortest flights. Miles cannot be used to purchase food on onboard (but a some UA hubs they can be used to purchase food -- again 1,0xx miles is too little)
UA presently does not offer pre-order flight food.
To earn miles for the flight, you should have you MP account attached to the flight before departure
