The flight, the pilot, the flight crew, and the ground personnel were all great, despite the sudden and lengthy FAA Ground Stop in Boston, which SPIRIT obviously had nothing to do with and no control over.

Flight and crew were good, no complaints at all. Easy, uneventful, quick flight. The delays, cancelled flight, hold time to wait for customer service on the phone were not good. One person that answered told me the delays, first on the way to Newark, and again on way from Newark were due to weather (there was no weather on flight coming in); turns out that was not true. Multiple flights were delayed and cancelled that weekend- 6 for the trip leaving on Sunday from what customer service at the desk told me. Newark was having issues with air traffic controller I believe. So, getting false information and only options of rebook (for another day, or one with stops to get in the next day), refund or a credit valid for 5 years, did nothing to help me get to work the next day or get my son home for school that next day. There was no sort of compensation for the wait or cancellation from airline or from airport. Just out of pocket for the uber ride and the missed hours at work.

Canceled my flight and refused to put me on a different flight to get me to my destination. Unacceptable and ruined my trip

Not great. Overpriced and charge you for everything. All but breathing was an extra charge. Never again! Oh if you didn’t check a carry on, you couldn’t use the overhead bins. Crew said those spaces were not available. Personal items MUST go on floor. Yet, there was only 50% capacity at best! So ridiculous.

Plane uncomfortable. Issues with engine caused a long delay, 2hrs, before taking off
