Flight was canceled and instead of rescheduling at the gate we had to go out to the ticket counter. Unruly kids kicking the back of my rows chair with staff to inattentive to say something.

Customer feedback I sent to Spirited today: “I will never fly Spirit Airlines again and will work hard to convince my friends and family to boycott/avoid Spirit Airlines at all costs. I booked three seats for me and my 8 and 10 year old children on NK 1222 from Orlando to Kansas City for 12/7/25 leaving Orlando at 10:37AM. This itinerary was abandoned by Spirit and we were rebooked onto Spirit flight NK 213 leaving at 9:06PM without any notice. Then the nightmare really began. Flight 213 was delayed a total of 12 times, finally leaving at 6:35AM the following day. The gate was changed 5 times and our electronic boarding passes were invalidated at midnight. The worst part was that the 12 separate delays were incremental making it impossible to plan for accommodations for my family. My kids missed a day of school and barely slept under the harsh lights with lots of noise on the filthy airport floor. The customer service agent at Spirit Airlines told us we would be emailed a voucher for a hotel which never happened. I asked about it multiple times and it never arrived in my email inbox. This whole unfortunate situation could’ve been avoided if spirit had taken a realistic approach and delayed the flight from 9 PM until 6 AM from the beginning. My son gleefully deleted the Spirit app from my phone once we landed and we will never fly with Spirit again.”
