but for the second time this summer, on a united flight between the mainland and hawaii, we were seated across from a family that diapered their kid in the seat (actually, when it happened in may it was an infant on the tray table, twice and this time it was a 2 year old on the empty middle seat, with no diaper pad or blanket or anything between the child and the seat).

last time flyertalkers were like "take a picture," but i did not want to whip out my phone and flash it in their kid's butt...and the mother had been pretty upfront about how wild her kid was going to be on the flight and i didn't want to tattle on her....but is it too much to ask that united take some interest in mentioning to passengers that seats/ tray tables are not diaper tables?

is this just considered acceptable behavior? just like last time, the flight was not under seatbelt lockdown when this happened...just a routine diaper change...but once again a big yuck.

and then the used diaper was placed by mom -- raw- not in a baggie or anything-- in the seatback pocket until the end of the trip when the fa's collected our trash.

does this happen on other carriers?
