This was worst experience of my life., with lufthansa airline. On sunday 23 rd june 2019, i reached vancouver airport at 11.00 am thinking that finish all boarding formality and relax in lounge. As i went on desk the lady said that she did not have any details of my tickets and she asked me to get the transfer from air canada. As i rushed to air canada window they said that they have already transferred the deatails to lufthansa air.
After so much discussion a gentleman issued me the hard copy of the details. It took me almost hour an half finish all this. I went back to lufthansa with all the details. Now the same lady came up with new issue, she told me that i can only have one check in baggage per person. Whereas my ticket clearly indicated 2 bags per person. And i did travel with 2 bags each when i came to canada. But she refused to listen and she asked me to pay cad 320. Again i had to rush to get the money exchanged, as i come up on the counter to pay the amount another lady asked me for cad 330 and she was not ready to cooperate at all as i was getting late to board. Again i had to rush to get additional cad 10, i went to the counter and paid the amount cad 330, as i was still there, now she asked me i will have to pay cad 191 instead of 330 and i will be getting the refund of the difference on the departing gate d 55.
I ad fellow customer with the same problem traveling with me in the same tour program. And his all 4 bags were checked in for free, where as i had 3 bags between 2 o[censored]s, she charged me overweight. I would request to look in to the matter as i had to go through so much hassle.
