I have a 6am BWI-ORD flight on Spirit coming up and am worried about these ongoing Spirit flight cancellations due to lack of crew that have affected my specific flight 5 out of the last 7 days.

Booked this with my CSR. I will need to get to ORD that day for a U2 concert where I have a non-refundable and non-transferrable VIP ticket to the show. If Spirit cancels the flight, is there any benefit that will reimburse me for the cost of a new airline ticket on a different carrier to get me to Chicago that same day? We all know how awful Spirit is at rebooking customers on other flights (they basically don't.)
