I’m on a flight from ORD to CLT , I connected to the inflight Wi-Fi because it allows you to use the AA app or a web browser to access AA’s site for account management or to check the status of flights. Having missed my first flight from ORD to CLT because my plane got delayed from BWI( don’t ask ) . I wanted to make sure my flight from CLT home was on time and I would be able to get a seat. I looked down and saw this.

I thought it was odd it showed “VZW Wi-Fi “. Did their free limited Wi-Fi allow my phone to tunnel back to VZW ? apparently yes it did. I was unable to send iMessages but SMS was allowed , texted my wife and friends through SMS and to my surprise got texts back.
Thanks AA !
