Good! But your flight crews don’t need to ‘eat the mics’ when making announcements. If they held the mics 3 to 4 inches away from their mouths, we could understand them so much better. Otherwise, all is well.

Your flight crew and boarding area crew need to have microphone use training. They all hold the microphone right up to their mouths, way to close making understanding them almost impossible. The microphone should be held about 3 to 4 inches away from their mouths. This would provide for much better clarity through the PA system. ‘Eating the mic’ DOES NOT work.

It was the first time I flew on that airline and had a very positive experience. Nearly identical to Jetblue which consider the standard of airlines excellence.

A bottled or canned drink, whether water or soda would have been appreciated upon settling in and flying, without being charged for it.

Horrible experience. First and last time using this airline. Made an announcement that boarding will start in 15 minutes, canceled the flight 5 minutes later due to no airline staff. Had to book another flight on Delta since Spirit had no other flights arriving to my original destination the same day. I wouldn't recommend anyone to fly with Spirit. No wonder why it consistently ranks high among worst airlines.

Once again, the staff seem to think they are above the customers and treat everyone with disdain, belittling people.
