Cheap Business Class flights to Iceland

The flight experience was good. The problem was the situation I faced with them prior to the flight. I bought in Dec 2023 the flight Geneva to Reykjavik, I paid more expensive than the other routes, because I wanted to have a direct flight. In April 2024, they cancelled the flight and rebooked me with ITA Airways and Icelandair. So, it became ITA Airways from Geneva to Rome and Icelandair from Rome to Reykjavik. Two days before I called them because I could not do my check-in with ITA Airways. I called them and they told me my flight was rescheduled only from Rome to Reykjavik. I said I lived in Geneva and this change did not make sense. They told me they should have offered to me the closest airport and the refund. The person speaking with me had no idea what to do and said they would call later with a solution. Finally, they called and said Rome was the only way. I told them that was an absurd and they should pay my Geneva to Rome flight. They even lied saying there was not more seats with ITA Airways, which was a lie, since I saw that I could buy tickets yet. They just did not want to take the cost. Finally I remembered she said they should reschedule with the closest airport and I told that was Zurich. They rescheduled me, but I had to pay train tickets from Geneva to Zurich and Zurich to Geneva. Terrible experience. Terrible customer services. Worse airline I ever had the bad luck to buy a ticket.
