We're booked on a 777-200 from SFO to DEN in Aug. We selected seats 40a and b, a two seat row. There was no fee associated with these seats. However, other than the United site, I haven't found any seat rating site that contains a 777 with that configuration. I'm trying to figure out whether the seats are especially good and should be kept or have downsides such that we should move. Any help would be appreciated.
