There recently has been "noise" about JetBlue having the ability to identify IP addresses, and store buying profiles. When they find customers who will buy higher fares, they supposedly skew offering prices. There has also been discussion about ticket buyers with Apple hardware, being offered higher fares, the notion being they tend to be higher income types. That kind of data mining could be contributing to browser issues. In my case, both my smartphone, and Google Chrome browser, cannot connect to the B6 website unless "cookies are enabled".
