T-Mobile to install Wi-Fi in remainder of Delta Crown lounges in airports: This deal was announced last fall, but only a handful of lounges were equipped. Now, they're installing all 40 nationwide.
Interestingly, as I talk to folks in the airline industry, it's becoming clearer and clearer that this carved-out lounge deals could wind up getting wiped out, not grandfathered, as airports stop renewing leases on airlines -- turning them into renters or imposing new conditions -- and build out unified Wi-Fi infrastructure. Of course, that means that a provider could still offer access on the infrastructure and only allow lounge members to access it, but that seems less likely.
