Everything was terrible. Flight was delayed several hours, crew was abrasive. Stuck on runway for over a hour. There was an argument between passengers that nearly turned into a fight while waiting to exit plane, crew did nothing. Took nearly 3 hours to retrieve luggage at baggage claim. Lost an entire day of vacation. Will never fly spirit again under any circumstance

The flight from Boston to San Juan was boring since you guys don’t offer wings if during the flight. The returning flight was better offering WiFi to passengers. The food was horrible not enough on stock.serve paying customers better.

There absolutely needs to be WiFi on flights. Not sure why this new aircraft did not have the capability, but it made for a very frustrating flight. I honestly would have paid twice as much for another airline to have WiFi as an option, especially as a mom with kids who have disabilities.
