This flight was one of the worst I have ever had in my life. I wanted to pamper myself, so I bought business class. I was looking forward to my new experience. I will not mention the chaos of changing gates several times, as these things may happen. What surprised me was the lack of attention to passengers. The flight itself was delayed by almost 3 hours. Even though staff offered vouchers, we had no idea where to get them, and we were told that we only had about 10 minutes to use them because boarding had already begun. Firstly, I did not see anyone with the voucher, and secondly, even if we got it, we were not able to use it. When I finally got to the airport, there was another waiting for about 30 minutes after cross check. Meantime, we were told that due to problems, they did not load any food, so the flight will be without any food on board. The only food offered and given to everyone on the plane was a small bag of nuts. As a business class passenger, I was offered drinks only. All in all, my business class contained 3 small glasses of juice. This is the business class on British Airways. Due to their delay, I missed the last coach, so I had to order a taxi as I travelled to Slovakia. This cost me another 160€. I received no apology or compensation from the company at all. If this is business class with British Airways, I am more than happy to use cheap Ryanair or Wizzair instead. You will get the service you paid for. Unfortunately, I cannot say the same about British Airways. It was a disgraceful and cheap service for a very expensive price. I must admit that I have used them three times in my life, and every time I used them, there was a delay and an issue. Having had this experience, I would not recommend this company to even my worst enemy. A big shame on them.
