Absolutely everything about this flight experience was awful. My flight was initially cancelled due to Hurricane Ida, but at no point did I feel the customer service was aimed at helping me find a way home to New Orleans. My flight was then changed again last minute without any warning or timely communication, removing me from the flight altogether and rescheduling me, (again, without my consent or knowledge) for a flight to Baltimore for the next day. Still trying to figure out why they thought that was a good choice, taking me even further away from my originally planned destination and now devastated home. The gate agents were overwhelmed with the number of disgruntled and confused passengers (I was not the only one who was switched to a different flight without consultation) and were frankly unprepared for the number of passengers who now needed assistance, further delaying the boarding process & flights for everyone onboard. I learned my lesson trying to save a few extra bucks. I will never fly Spirit again.
