Lost my luggage and terrible experience with customer service trying to track it down

Lost my luggage and terrible experience with customer service trying to track it down

Flight departure was 90 min delayed, and the boarding experience was confused, stressful, and generally poor. Additionally, the wifi on the plane was malfunctioning for all but the final 15 min of the flight into ILM.

Boarding at BDL gate 24 was confused, but balanced out by friendly, responsive gate attendants. The crew were friendly and made for a straightforward flight. Seats were fine, but the aircraft needs to go in for cabin maintenance. The air nozzles overhead were all loose and could not be closed or adjusted.

The return flight was soooooo much colder than the departure flight to Connecticut! I appreciated the layover because I didn't have to change planes. The staff and the service were the best! Everyone was so professional and accommodating. Having internet was great, but for the movies the flight offers through the app could be updated. THANKS EVERYONE! I fly BREEZE every opportunity I can get.

I was surprised at how wonderful it was. The aircraft was clean. The crew was warm and welcoming and as a result the passengers were friendly. One warning the only free thing was water. I kind of liked picking wet hat I was willing to pay for and what I was willing to skip.

The flight wasn’t big on frills, which is fine with me. I flew into Islip MacArthur Airport, which saved me from having to go through LaGuardia to visit friends on Long Island. It was inexpensive and super convenient!

Really appreciate the great crew and pilot for keeping us informed about everything going on, updates, etc. It's so reassuring just to know (for example) why there might be a delay, etc. I'm very satisfied with the excellent service.

This was my first time flying Breeze. The plane was one of the nicer planes I have been on. The flight attendants were friendly and helpful. I will fly them again.

Easy boarding and great communication, smooth flight- all was great!

Food and entertainment were non-applicable here Flight and boarding were great

It was good. Last flight was delayed but I always say that is in God's plan

Flight coming out of Buffalo was delayed, so we had to be rescheduled on another flight from Baltimore to Phoenix which means we had a long layover and got home 3.5 hours late. Shuttle to parking stopped at 10pm, so we had to pay for an Uber to the parking lot and got charged an extra day of parking since it was after midnight. Not the best experience. Long day!

Plane was late. Zero service for 2+ hour flight and it was not that bumpy.

The staff was very friendly, professional, and courteous. The overall flight was a great experience.

southwest just starting charging for luggage. hadnt realized it until it was too late. now out $70 when i couldve bought a carry on if i wouldve known. free bags was one of the only reasons i chose southwest over another airline (the other being no assigned seats, which is apparently also being changed). stupid business decision. wont be flying southwest anymore.

Cluster mess boarding. Can't wait for SWA reserved seating. Internet didn't seem to work on the plane.

The price of the tickets isn't matching the flight experience. No matter how long the flight is, you're only getting pretzels. The flight attendants looked unkept and over it.

I liked the boarding by group and numbers. I didn't like my inability to guarantee our seats together. I didn't like the $8/flight for Internet, but I did appreciate the inflight movie options on their app. I didn't like that there were no charging stations on the seats during either of our flights. One flight was over 3 hours.

I never like the fact that if I don't check in exactly 24 hours before the flight time, I get to board C, and that means sitting between 2 individuals. I would like assigned seating in the airplanes.

Flight only half full. Room to spread out. Newer plane. Very satisfied.
