I went on a trip from London to Vienna and it was an absolute nightmare. For context, I am a 20-year-old female student, and I was solo travelling with a transfer on both the outbound and return journey. My outbound journey was to stop at Cologne, and was delayed for 3 hours at departure. I was to miss my transfer in Cologne, and no attempt was made to contact me in regards to booking me onto the next available bus, as stated on the help page. I ended up having to look for my own alternate form of transport, which was significantly more expensive than my originally planned ticket, and was stranded overnight in Cologne with no food or water. Mind you, I was later made aware that I was not to receive compensation for my delayed journey as I decided to take it anyway, and rather than refunding my more expensive alternative bus to Vienna, my original ticket was to be refunded, which was appalling enough as is. I thought the nightmare was over, but my journey back proved to be significantly worse. Once again, my bus was delayed, and I was going to miss my transfer, this time in Belgium. Once again, I had to book my own alternative transport, as no attempt was made by Flixbus to rectify their own mistakes. This time, however, I was stranded overnight for a whole 12 hours, and had to organise accommodation myself. I would like to remind you that I am a female student and felt incredibly unsafe and abandoned in an unfamiliar city, and was lucky enough to even find room in a hostel that I had the funds for. My subsequent transfer suffered only a minor delay at departure, but missed the ferry, due to which we were stuck at the port for ages - once again, no opportunity to get food or water, absolutely boiling in the bus. While I did manage to get home (fast-forward 48 hours, for both journeys), it was already nighttime by the time I arrived, so once again I was left incredibly vulnerable. I feel the only fitting description of my experience with Flixbus is Murphy's Law: 'Anything that can go wrong will go wrong'. I am shocked at just how uncooperative the company was, and even at the state of the delays of the buses, and I can safely say I will never be taking ANY journeys with Flixbus again.
