Near 4 hour flight with only 1 service. Had to use call button to request water. Internet and power not working until into flight. Internet would stop working during flight.

Near 4 hour flight with only 1 service. Had to use call button to request water. Internet and power not working until into flight. Internet would stop working during flight.

Southwest's seats are the least comfortable I have ever sat in.

The cabin was quiet for the redeye flight. The area was clean. The staff was great. The 787 Max was in good condition. Drawbacks were that the seat widths were tight for some passengers. The seat padding was at best average and for a long flight uncomfortable.

Southwest like most American domestic airlines, is a mediocre airline. But it is among the cheapest. Oh well.

My flight was delayed 50 minutes and we were rushed to board to then sit for 15 minutes until the pilot arrived. Unacceptable since we could have waited to board. Also the delayed flight was updated AFTER we boarded to more than the 10 minutes as originally stated.

Other than a bit of a delay, everything was good. Again, the boarding process and picking seats is the only thing I don't enjoy.

If we are going to have to pay for luggage, make it easier to do. Put something on the app during check-in so I don't need to do it at the kiosk. I've done it twice recently and I ended up having to pay at the desk because something went wrong at the kiosk in Tampa.

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.

The quality of Southwest Airlines continues to degrade each time I fly with them. If it were not for the free luggage, I would probably choose another airline. Their prices are a little bit competitive, but way too high for the quality of the service. Southwest is not unique in this way. Domestic flight in the United States of America has continued to be a lower and lower quality product. Very sad when you compare the quality of domestic airlines to that of many international airlines around the world.

Very smooth checking in our luggage with a super pleasant SW agent. I enjoyed a fun entertaining movie.

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.

Head rest did not move, very uncomfortable. Staff was great. There was no entertainment, would be nice not to have to pay for snack.

Worst airline - on our flight down from MCO to EYW, there was a huuuuuge delay. We were supposed to take off 12p and it was pushed back to almost 2:30p. We boarded the plane and then sat on the tarmac forever because we were "over" weight and had to burn fuel. Rather than ask guests to volunteer and leave, they kept us on the plane. Finally a family decided to off board and take their luggage with them. Shortly after, we left the terminal but then the pilot told us we may have to sit at the end of the runway for 15-20mins to burn more fuel. Which we ended up doing and of course it started to rain. We finally took off 2:50p. We were supposed to land 1p and didn't land until 3:45p. Basically had time to scramble off the plane, grab our luggage, request transportation to our hotel, unpack, rinse off and hustle over to our 6:30p dinner ressy. It's a shame Breeze is the only non-stop airline from MCO to EYW. For this, not sure I'd ever go back to EYW - most def will not take Breeze again.

Flight was rescheduled from (originally) early Saturday departure to a late Sunday departure. Then the late Sunday departure was delayed again (weather) and got in very late. We’ve enjoyed Breeze a lot, but this particular experience was a little disappointing.

Breeze was good but the sandiego airport had traffic and waiting 1 hour in the plane till take off

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.

The flight was comfortable with the usual slight turbulence. Macadamia Nuts would be great snacks to purchase in flight.

This is one of the worst trips that I have ever had. Ending up with an overnight delay. I’m not happy with the fact that they did not provide and set up the arrangement needed for lodging that we had to do it on our own. I also feel there should’ve been Compensation for food.

Had to approach landing twice which caused concern but probably due to weather

This was my first time flying your airline and it was okay. The people were nice but I am not used to all the add ons and no movies or even water. But I knew it was going to be that way. I think I prefer paying for the extras to be more comfortable.
