New high end luggage ruined/zippers broken, items missing. All happened on return flight from msp to mso. Do better! Not store bought luggage but high end personalized ogio custom embroidered luggage. Total slap in the face ontop of an extra luggage fee that took me 3 hrs on chat to resolve.

Third flight in two months where the crew was not there. Comfort seating does not guarantee overhead bin space. Passengers with children are allowed on the plane first - if you are flying to and from Orlando, this means half the plane has boarded before you get on. And somehow all the bin space is taken up. 3 out of 5 flights have had issues with equipment or procedure. Some of these instances caused the flight to be delayed because of a "nuisance" light. One time it was a bag that had been brought on board but did not belong to anyone so we had to return to the gate. Last night we were told the "AC" on the plane doesn't work well and we're 10th for take off- because the crew was late - and that it will get cool when we're in the air. Not sure if this is usual, but I didn't think flight crew could jump seat in first class. Movie and TV selection has not been refreshed for several months- flying one to two round trips each month easily exhausts the list of content.

Definitely a southern flavor. Cordiality was evident even though no drinks or snacks were served.

N Everything was perfect from boarding to assistance to baggage in Tampa

Flight was delayed by 3-hours and their fix was… complimentary pretzels.

It was a great flight and the stewards and stewardess were all kind and accommodating!! The seats were comfortable and entertainment screen excellent!

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.

The flight was overbooked and the staff at the gate started calling for volunteers to drop out and offering incentives. That delayed the flight

There was no wifi even after my husband paid for wifi it wasn’t working. The plane looked and felt old.

Update the cabin with tv screens or at least music sources.
