Attendants were pleasant and the flight was smooth and relaxed.

It was fine. No drinks nor snacks offered though. I thought that was unusual.

Things were delayed a little. But that didn’t affect my plans. It was fine. I was surprised it was so full thanksgiving day. The crew were friendly and professional.

The flight was delayed multiple times, again no fault of American but again the extra cost, for everything makes it feel like a cheap airline! Especially when flights are outrageously expensive already

we landed at cmh ten minutes early but had to sit on tarmac for twenty minutes because a plane was at our gate despite the fact that 3 other gates were open.

I have a gluten allergy so did have any food

We were very rushed by a staff member at the gate when transferring from American Airlines to Fijian. Then the plane stayed put for ages anyhow! The plane was delayed and my bag sent to San Francisco instead of Fiji

Wish some foods provided rather than just biscuit/cookie for flight more than 2 hours

Flight was delayed leaving Dallas. Arrived about 2 hours later than scheduled.

The only thing to like was that we eventually got to our destination

Honestly horrible. The plane on the way back was delayed 6 times with no explanation on why. When I asked for a refund or some money back because I had to miss a day of work because of the desk, they told me no. Because of how poorly it was handled I will most likely never take spirit again

I hope you continue to be one of the great company

I stopped flying spirit as much because they are crooks and thieves. It's not like other airlines where you can at least get credits they just take your money.

Always comes in handy when I want a quick weekend getaway.

The entire staff from check in agents to flight attendants were pleasant and professional. Would suggest a complimentary water.

Spirit is low fare air line. Food also cost you. No free food.

Everyone was kind for the most part. I did travel with children and paid for seats and even then it was not as suitable. I tried calling their customer service prior to check in and I was told they couldn't help me because I didn't purchase my tickets with them.

I think the staff was nice. They took time to explain safety protocols. Boarding was great. They started early and our flight left a little early which was convenient. Having free games to play would have been better

Just total easy flight experience!! What could you do better..? Hmmm..? There was nothing I can remember. Spirit was a far more comfortable and easy process than American, United & Delta. I'll always look for Spirit and I've told a few people about, since flying this past trip!! I'm a SPIRIT FAN!! Thank You, SPIRIT AIRLINES!! Very, VERY well done, 100%!! See you...SOON!! -Best, Linda R.

The flight was 3.5 hrs delayed. I was not notified prior to arriving to the airport via spirit app. or via boarding pass that I already had loaded on my phone. The agent that i saw at the counter didn’t mention anything about the delay either. I only saw the update after logging in to my email account.
