APC is listing that all Delta mainline fleet is equiped with wifi, however, I don't believe that to be true, so wondering if someone can confirm that for me, purely to satisfy my own burning curiousity. I was just on a DL 767ER twice within the last 2 weeks and never heard any announcement about wifi. They were int'l flights tho, so not sure if they activate the wifi on long-haul flights.... Thanks.
