Bad idea to guarantee. Even airlines tat gave wifi it usually varies by flight. I used to fly AA and it was hit and miss at best which flights would have it. US Air also has on some flights. United is so far behind the times no WIFI or Directtv. I don't care as much on CO as I use Directtv and work on email or something I don't need Internet for. Good Luck with our wife. I would tell her the truth as it is not hard info to find out and she will be even more mad if you lie to her.
