Rules of Priceline

Here are what I think are the rules Priceline abides by in the order fo thier importance. You will take advantage of these rules to get a cheap flight (remember your goal is to go for less than 75 each way)

1. Priceline allows you to book until 4:30 PM in the time zone of the airport you are departing from
2. Priceline garuntees the date you depart and the day you return
3. Priceline will attempt to book you on the cheapeast flight
4. Priceline gives you at least 3 hours between the time you book and the time you have to fly out
5. Priceline offers no garuntees on the time (but they do garuntee the day) you are flying back

An additional rule is required (as suggested by a commentor):

1. The airline is offered a choice - fly you or fly an empty seat. They would rather have you on
