Is Delta really prepared?
Not all 100% of the passengers on a Delta flight are nice people, some, even, might be scary seated next to a child.
Will it take is one accusation of "inappropriate behavior" with a child sitting next to a stranger with no parent next to them to have them rethink this?
Even if one is willing to pay the additional fee for to be seated together, there will be occasions where there are no available seats together...No?
Is it REALLY over 5 as being considered as able to fly "unaccompanied"???
