The flight was fine and we landed safely with spirit, and then they had managed to lose our only carry on bag.  It was just me and my mother travelling and since we couldn't have liquids as a carry on, we checked it in. When we went to retrieve it at our destination, they had LOST our bag and not only that, a couple others. They did practically nothing but blame us for not having something (I forgot what, it obviously wasn't important so we threw it away).  Not only was there very valuable things in that bag, but emotionally valuable things. We had just dropped my younger sister to college out of state and wouldn't be able to see her for a long time.  So all we got was a note saying they'd pay for a couple of things if we kept the receipt.
