Problem with flight change
Hi I have a flight from brussels to lima with a layover with in Barcelona by iberia. However the flight from brussels to baarcelona is operated by vueling. I received an email from iberia saying that my flight from brussels to Barcelona has been changed. So now, I miss my connection from Barcelona to Lima. The problem is that the change is not visible in my booking with iberia. However, iberia gave me a reservation code for vueling. And in vueling, the change of the flight is visible
I also called vueling and they confirmed that my flight had been changed so now I miss my connection. I called iberia and they told me that since the change is not visible in their system, I should ignore the email I received. Vueling says they cannot do anything because the reservation is under iberia. Iberia says they cannot do anything because the change is not reflected in their system. I have called iberia twice and asked to speak to the supervisors since they did not give me any solutions. Both times they did not want to refer me to the supervisors.
Does anybody have any experience with something like this or any advice?
