Now, I'm not one to normally complain about such things usually, but if you haven't heard about this, it's worth a look.
This link is to a video shot on a Jetblue flight of some passengers getting into it about unruly children. And...the grandma ended up being detained for shooting the video. I love it.
I'm gonna have to agree that I think screaming children on a long plane flight is unbelievably annoying, especially if you're trying to sleep. Parents have to assume a measure of responsibility when it comes to that kind of travel, and not necessarily blame the airlines for it.
This one's also good:
I love how they were about to use 'restraining tape'. Whoopee!
