Mirabile dictu, the UAL terminals (7, at least) at LAX now have Tmobile WiFi. I spotted the access point on top of the gate counter, and checked it out while waiting for my plane last night. Previously, WiFi was only available via leakage from the United Red Carpet room.
Booting up, I quickly spotted the Tmobile access point. I did hesitate a minute — recalling security warnings past and current, even tricksier hacks, But I went ahead with it via a VPN client, since the one on my laptop for company access includes Tmobile access. That made me feel quite a bit more secure, it worked like a champ, and the charges were automagically routed to the company rather than requiring a credit card of my own.
Wasn’t there long (fortunately), since I got on stand-by, but it was nice I could get on at all. Did some office work, a bit of writing, and then headed home.
