This is so off-base I don't even know where to begin. "Maybe you just don't get to ... ride on planes" -- so the kids never get to meet their grandparents or great-grandparents who are too unwell to make the trip because you won't give them a screen for an hour or two? Like everything else in life, dealing with screens is a balance. Every day for multiple hours is too much; a couple hours on twice-yearly trips is not going to have any effect on them.
