Unfortunately, usual rubbish at the gate for SAS reporting that boarding is underway, but clearly that was not the case. Internet worked to start with, but at some point it wouldn't connect using any of the devices I had with me and remained that way for the rest of the trip; could not even blame being out of network coverage, for all of that, as surely it should work across continental USA - worked for so little of the flight for me that I wouldn't have advertised that such a service was actually available; if I had had to pay extra for internet, I would have been demanding that money back.
