Bad experience. Unhappy with the changing of flight times and one particular flight attendant (Bartholomew) on our flight from Orlando to Detroit. Traveling with a large family of 7, including our 18 month old, can be arduous but when the airline changes your flight time from landing at 9:30 pm to landing after midnight, this becomes much more difficult. When our 18 month old was predictably over tired and fussy, my wife and I tried to move to an open row so we can console her more effectively. The flight attendent rebuked us and said we could not sit in an exit row. We were not planning on sitting there for more than a few minutes but just to have space to console our screaming 18 month old. Spirit did not allow for a family friendly trip. Likely will be choosing a different airline next time.
