On July 13th, 2014 my colleague, Zephon Howard and myself, both students in China returning home, were denied boarding onto a Vietnam Airlines’ flight VN513/VN37 from Beijing to Frankfurt. From Frankfurt we were to transit on to Condor Airlines DE1258 to Tobago. The agent at Beijing explained to us in both Chinese and English that we were not allowed to fly because we required a visa to transit Germany's Frankfurt International Airport. This however proved to be false when I contacted our local German Embassy in Trinidad and Tobago. They informed me that we were allowed to transit Germany if we were to transit in less than 24 hours. Our connection time in Germany would have been from July 14th, 2014 06:00 to July 14th, 2014 13:35, well within a 24-hour time period. Due to being denied boarding onto VN513/VN37 we missed our connecting flight DE1258 to Tobago. We provided both our Vietnam Airlines and Condor Airlines tickets to the Beijing agent. We then had to sleep in Beijing International Airport and await the next morning to purchase new tickets on July 14th, 2014 on Asiana Airlines and American Airlines to Trinidad. US$1413 extra was spent in addition to the initial US$1136 due to the Vietnam Airlines' agent’s error bringing a total of US$2549 in the entire ordeal. This has been very costly and it was due to an error from Vietnam Airlines. We have been in contact with the manager of Vietnam Airlines at Beijing and requested that Vietnam Airlines compensate us the cost paid on our travels. The manager at Beijing Airport has been very unhelpful, initially when we were denied he hid from us when we sort him out for proper explanation, he has even called me "immature" in his email replies. He is very unprofessional and has since changed the reason that we were denied after we provided the German Embassy information starting we were allowed to transit, claiming that we never provided an onward ticket from Frankfurt to the agent.
