There is a brand new Ipass partnership with Scandinavian Airlines
https://businessclasswifi.com/
19.95 Euro / mo (apparently auto renews until cancelled)
US Customers - you can select US as country of residence. US credit cards OK
Covers up to 3 devices
Uses Ipass client, Apple, Android, and Windows apps available.
Each device goes through the Activation process described on this (or the DL) thread. I set up an iP7, an iP7+, and an Air 2, no probs
BUT:
Can I also use the service in a SAS-airplanes or other airplanes?
Inflight Wi-Fi is not yet enabled, but it may get enabled in the future when the service is wider available.
Personally, I'm delighted with this current deal as I used to have Ipass provided by my former Megacorp and it was sweet.
Mrs JT8D and I have a 4 week Asia / PAC trip starting next week and look forward to the Ipass ease of use at hotels, airports, etc. Just to be sure, I'll check the actual onboard connectivity, or lack thereof, on DL and AA and report.
