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

10 hour delay with minimal updates. Couldn’t leave terminal and then ended up on redeye with a dirty broken plane. It is literally impossible to reach customer service via gate agent, app, phone, text or email.

I thought that I had pre-purchased carry-on luggage and was surprised when I tried to check in that I did not have it.

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.

Great experience and In love flying in and out of Provo airport

You get what you pay for. It’s like a bus but flying. No frills, no snacks. Leg room was fine, boarding was good.

Overall good. Plenty of legroom and fairly comfortable seats. No issues with capacity and the overhead been even though most people brought several carry-ons on. I don’t think Breeze really enforces the pay for a carry-on rule.

Surprised at how much I enjoyed Breeze. Paid for the Nicer upgrade which made it closer in price to a flag ship carrier but with more comfortable seats and much more leg room. Crew was polite and since we brought our food no loss there. Would make the point that the ‘have to pay for a carry-on is BS’. Most people did not and had several. Still was plenty of room in the overheads.

Comfortable seating, adequate space available, nice to have USB port, polite crew.

My experience is typically great with Breeze. This trip wasn’t any different.

WiFi did not work. Boarding with the new seating assignments took too long. The temperature in the terminal was obnoxious. +/- 80°

The seats are now more narrow. I paid for front row the seats in the front are even more narrow than before.

Only downside was the legroom and seat width, which is always a problem unless I spend more for a premium seat.

My flight from Denver to Minneapolis was excellent. My flight from Minneapolis to Denver was one of the worst I flights I have ever experienced. I had a window seat, the gentleman in the middle seat was morbidly obese and SW should have made him purchase two seats. His elbow dug into my arm most of the way even after I asked to please be careful. I was literally squashed between the him and the window with no wiggle room. The plane was full so it was not possible to ask for a different seat. I realize I should have complained to the flight attendant but I didn't feel anything could be done to rectify the situation. I fly SW often, I will continue to do so as this was my first negative experience.

I was assigned seat 7E, yet my boarding was Group 5, which caused me to have to put my luggage in the back of the plance above `19 or 20 aisle, as passengers who had boarded earlier took the overhead bins in the front. SW needs to monitor bin space and ensure that bin space above the seat are aligned to those sitting near their seats. Also the seating assignments needs to align with group number. Maybe board those last first and so on? Having said the ALL the passengers on the plane were gracious enough to allow me and other passengers in this dilema to retrieve our luggage and helped us along the way. I always love the flight staff, as always their fantastic and I can't rave about them enough!

I appreciate the staff who allowed me to board though I arrived a little late! Regarding the assigned seating, I had booked my flight before this change and wasn't aware of the change at the time, and so I didn't select a seat at booking as I didn't realize it was relevant. Better communication about the change would have been helpful for preparing.

Flight attendants very hospitable and friendly. Pilot flew a smooth take off and landing.

Paid for premium extra leg room but the bin space for rows 1-3 had to go in rows 4-6 and 4-6 had to go to 7-9 because flight attendants have snacks and their luggage upfront. So we pay extra to have to fight thru traffic to get our bags. Only 2nd day of new seating so hope they fix this.

WIFI was great. My selection for seating is an aisle, but during my trip, I never had an aisle seat. If we can get that corrected, I will be thrilled. No snack or drink on this flight.
