there is working a trick for long distance flights. I used it a few times to get cheaper tickets: when you are buying long distance flight tickets, pick a city close to where you will depart (this will add an additional flight transferring from your departure city). When you get multiple transfers there is a possibility that the offered price will be cheaper (I confirmed this with an agency when I initially figured this out). If you get a cheaper price buy it and call the airlines to tell them you will miss the first flight, and have them correct the check in location to your departure city. I was able to save $100 travelling from europe to east coast last time I did this.
