Planned a three day trip to Vegas. Flew Spirit out of Detroit. The flight was delayed 9+ hours. Boarding should have occurred on or about 9:20 pm on June 1 with a take off of 10:02 pm. The flight took off at 6:20 am the following morning June 2. The gate agents provided very little information during the delay other than they were waiting on a pilot to come in off another flight. During the wait time, the pilot that did show up "timed out". Eventually the staff announced the flight would not leave until 5:15 am the next morning. Frustrated customers were given the choice for refund or to book on another Spirit Flight. Customers were so angry with the gate agents and Spirit for the delays, lack of communication and overall attitude that local police were brought to the gate to supervise Spirit's shenanigans. Vendors close early at Detroit Airport. For those of us that could not rebook a flight, no food vouchers were offered, no hotel vouchers offered and if you wanted to rebook a flight, only Sprit was offered (no other Airlines) forcing Spirt customers additional days of delays. When it came time fly out the following morning, a pilot was late causing a flight attendant to time out. In 9+ hours, Spirit couldn't get their stuff together even leave close to on time the next morning. Tried to resolve with customer service. No response from Spirit's CEO, and Spirit's customer service agent was useless. Do not fly this airline! They do not deserve you! During the process of dealing with customer service, I had booked a flight with Spirit in September for which I asked them to cancel and refund. Even with all the issues, they would only provide a credit for the flight. I advised them to donate my credit to charity. I will not fly Spirit again. I advise you to reconsider Spirit in favour of an Airline that will treat you with respect.
