Bradley Airport, I salute you: BDL, the airport serving Hartford and Springfield does what all airports should do: They provide free wireless connectivity to the Internet for passengers using the airport. They are wise and considerate to do that. On the other hand, Nashville’s Airport (BNA) still wants to make $7 each from passenger who desires to use his or her computer while passing through there. BNA provides free air-conditioning. It provides free access to restrooms. I think it’s time they join this list of enlightened airports who do the same for wifi.
