I mean, it’s Spirit. But it was frustrating to have our flight canceled, get bumped to a later flight, and then Spirit was unwilling to check our bag until 4 hours before our flight… tell us we could not sit in the waiting area’s chairs… and really negative experience getting checked in and dropping the bag.

2.0 Poor

Not having it be changed after we bought the flight tickets from a direct flight getting in at a reasonable time to a connecting flight red eye of 9 hours, so that we would lose our 35 dollars in nonrefundable insurance would've been great! Our country really does need low-cost carrier options, but this type of "service" ain't it. Fortunately, had a little better success with them flying to and from San Juan PR last month at least.

All was good expecting the seats need a bit of cushion. Besides that I can’t complain.

You get what you pay for, and the flights went smoothly. There’s no reclining chairs, no screens, And there isn’t always wifi, but the plane was clean and staff was friendly and the takeoff/landing were smooth.

The only positive is that the flight made it both ways. Getting charged for every little thing after the cost of the ticket itself is comical, considering how the plane and services are as bottom-tier as possible. The self check-in kiosks are useless. It’s nice to think that you can print your boarding pass, tag your checked bag, and then just drop it off. But no, they still make you go through the line once you finish- what’s the point of the self check-in then? Any questions for the staff seem like the biggest inconvenience and were met with condescending responses. This was my first and now last time ever flying with Spirit. After all the extra costs, subpar plane and staff, I see no value. I’d rather drive the 13 hours than give Spirit another dime.

The flight was fine however what started as a reasonable priced ticket could have become an overpriced ticket with additional charge for carry on as well as checked bag $79 per bag per person each way. Additional charge for choosing one’s seat, additional charge for beverage and snack, we were on what was described as a new plane yet there were no audio/visual on the jet. A bare bones service but not at a bare bones price. Will think twice before flying Spirit again. 😕

Flight was delayed a bit, but that was expected (and updated), so really not bad at all for the price. Could’ve used one less email asking me to upgrade my seat; otherwise no significant complaints

I love Spirit. New aircraft, great cabin service, the airfares are low cost which helps me visit my hospitalized daughter anytime I can without paying a fortune.
