The communication between us, the passengers, and the BA team was awful. We were promised a 30 minute delay, which turned into a 2 hour delay. We were not being kept updated on the delay at all, leaving us all stranded at the airport. In the early morning hours we were told the flight would be moved. We were not informed of a time and we were not informed on what will happen to us.We were sent to collect our baggage. After we all collected our baggage, we were told we would be checked into a hotel. We weren't told were, just that we had to go to the bus stop. Once there, a woman claiming to be the manager, told us she didn't have the resources to find us a bus or a hotel and that we would have to make our own arrangements. I did not habe enough money for a hotel or transport, so I was stranded at the airport until 4 am. At this time passengers from my flight were returning from a bus they were told to take. They said the bus drove around for an hour and just dropped them back at the airport. I was terrified, because I had nowhere to go and I am on chronic medication, which I could not take. I was feeling sick and tired and so confused. It was terrible and I felt abandoned. At least 40 people were stuck at the airport with me. We had nowhere to go and security kept sending us out into the freezing cold because they didn't want us loitering in the airport. At 5 am in the morning we were told to get on a bus. We weren't told where we were going and I kept trying to explain I can't afford a hotel anyway. Finally a lady promised us we would not have to pay and said the found a hotel for us. I felt like I had some infectious disease, because the people in charge were incredibly rude and shoved me into an overcrowded bus. When I tried to find out what was happening, I was scoffed at and shrugged off. We got to the hotel at just before 6am. The hotel was great and the staff were friendly. The total opposite of BA and airport staff. I would have been fine at this point, but the next day, we were informed a shuttle would collect us at 4pm. That was pretty late for check in, but we felt we could make it. The bus was never arranged for us! At 4pm we kept calling and a shuttle was scheduled for 4:30pm. It didn't show. Another bus was arranged for 5 pm and it only showed up at 5:20pm. I was in a panic as I was very late for check in. After check in at the airport which was at 18:30 pm, we were told the flight was delayed to 22:15pm! We could have been spared so much stress if BA had just kept us properly informed! After getting onto the plane we were delayed by another hoir because BA confused our baggage with another BA flight. All in all the most terrible and frightening travel experience I have ever had. The situation was handled terribly and we as passengers were treated with no respect or even an after thought. I will never in my life fly with BA again. I will never recommend BA to anyone. Looking back now, I would have cancelled my flight with BA on that first day and travelled with another airline. My family was worried about me and my safety. PLEASE DO BETTER. WE ARE PEOPLE TOO!
