The Malaysian Airlines connection in Kuala Lumpur was terrible. They changed gates on us last minute, with no info or apologies. We were an hour late leaving, the line to security was awful and the security guards rude and unhelpful. The Malaysian Airline staff at the counter was dreadful.Holding a sleeping child and two bags and with another little child in tow, they made me put each of my boarding passes in my passport photo page without any help or kindness. Malaysian Airlines really needs to train their staff to be more kind and helpful! Worst service ever before getting on airplane in KL Airport.
