An email from AA today linked to an AA page (https://entertainment.aa.com/en/wi-fi/) that says T-Mobile customers can now get free WiFi on most domestic AA flights. I've flown them a bunch of times this year, as recently as early May, and not once has that been available. Did this really just change? Would be great, but would appreciate confirmation from someone who flew in the last week or so and used the free T-Mobile WiFi. Thanks
