I have bought plane tickets online many times but I have encountered a bit of a glitch. Since the Boston airfare wars have begun our October flights have gone down $51.00, on AA. Now I had planned to wait but this is even lower than JetBlue and better flights for us. However I can only get 3 tickets at this price and I need 4. Should I try buying 2 and then go back in and buy 2 more? We are traveling with DH, DS, DS's girlfriend and myself. As long as we have 2 seats together each , we don't need to sit all 4 together. Any imput on this? I would hate to miss this great fare!!!
