A flight was booked with Volaris leaving December 26, 2020. I received an email stating they have changed my flight to leave 24 hours later. This new flight does not work. In the email they provided two options..either change the flight or get a voucher. We tried to change the flight to next year on the same date date but that date is not available to us. The voucher only allows us to travel within 12 months from the day it was issued which will not work either. The email stated if those two options do not work to call but and find out other options. When i call they say i have no other options. in order to complete our travel this year i would need to book another 4 flights with is not an option as they will not give me my money back. I have tried to resolve this with a manager but they keep disconnecting me when i ask for one. I would like my money back as they have proven they are an unreliable airline. This is a significant trip and I will not be able to change everything if they cancel or change my flight again next year. reservation number A9M3NJ STEPHEN VANDER HART DIANA WEHRLI HAYDEN WEHRLI MIKAELA WEHRLI
