On 9th february 2018 I flew from amsterdam to hanoi with aeroflot with flight number respectively su 2551 and su 0290, I arrived and was announced that my luggage was not placed in the plane in time so I would get it back at my door the next day. I filled in the form and waited and the local staff called me to deliver the luggage. But when he arrived he came with very bad attitude and asked me "why I did not go to the main street to get my luggage but let him ring my door bell?'. My house is in an alley which is 50m away from the main street. I could not imagine how he can be so rude to me and the agreement from his colleague the day before was to deliver at my door. I signed and got my luggage but after that I found out the gold flying blue card I attached to my luggage was gone! I am very much unhappy about this. Aeroflot crew on that flight had a long and tired trip as so many vietnamese coming home for new year holiday, I appreciate their effort to make the flight pleasant as much as they could. But I do believe the ground staff can work better and I do concern about my card whether it would go to bad person and what they would do with it. Hope to hear your response. Thank you! Diep phan
