Thanks everyone.
My husband and I are going on long overdue long weekend vacation Thursday-Monday Labor Day weekend and celebrating 20th anniversary.
We are taking a morning flight out and an afternoon flight back.
I was surprised to see no wifi on the 763 and didn't notice that before.
Will definitely need wifi on Thursday to keep up with our offices. Not as important on return as it will be a holiday but have not been on a flight w/o wifi in very long time even when spotty.
Looks like maybe the 763 will not work for us.
