Only negative were the twin boys, flying unaccompanied, sitting behind us on return flight. They argued with each other loudly, kicked the back if my seat; etc. Very interesting that 2 young boys sitting across from them, also unaccompanied, told them to behave, several times. Luckily, it was only a 2 1/2 hour flight! Those boys, not related to the first two, were very good, all through the flight.
