Ever since Southwest starting charging for bags, passengers don't want to pay to check their bags, so the gate agents have to beg people to check their roller bags now because there's "not enough space". This was a terrible business move by Southwest.

Ever since Southwest starting charging for bags, passengers don't want to pay to check their bags, so the gate agents have to beg people to check their roller bags now because there's "not enough space". This was a terrible business move by Southwest.

Delayed flight. Nicest crew member was a SW pilot flying seated next to me who kindly move to seat the final passenger. Flight extra delayed. My cup of refreshment of ginger ale was so packed with ice it was literally 2 sips.

We had a nice flight. Boarding was easy, our seats were comfortable and the on board service was pleasant.

Service was great, boarding and exiting went smoothly, and the flight was very pleasant.

Southwest Airlines is behind the times with a woefully inefficient service animal policy that leads to major inconsistency and stress for passengers and crew alike. Despite so many attempts to share feedback and request better support, they bungled it once again and provoked a panic attack in the process, with no apologies or acknowledgment that their crew was failing to adhere to their own inadequate policies. WiFi didn’t work, flight was delayed by an hour, it was about what I’ve come to expect from Southwest these days.

Flights were full but SWA still managed to get everyone loaded and depart on time. No snack or beverage service on the first leg due to turbulance. Seats were clean but very little cushioning. Reasonable amount of leg room.

Our flight to Oakland was great bc the plane was new but it was delayed by 15min not bad at all. Over all it was an 8/10

Our flight to Vegas was delayed by almost two hours - I appreciated the updates but it was a bummer of a start to a celebratory trip. The delays meant we missed our dinner reservations we made a month ago so that was disappointing. Once we got to the gate, though, the crew did all they could to make up for the lost time and to keep it efficient and enjoyable, so I appreciate their efforts!!

There was a problem that delayed boarding for more than 20 min. and once everyone was on board, the plane did not take off for another 30 min. which then made our arrival in Phoenix 1 hour late.

Our two flights from GRR to MDW and MDW to OAK were both delayed due to weather. Be sure to build in a sufficient buffer in the transfer time to account for this type of problem. SW recommends connections as short as 40 min. Don't do this. We had to change concourses in MDW, a pretty long walk, to make our connection. Rule of thumb I use when traveling on flights with multiple legs is for connections of 80 min or more, unless there is no plane change, in which case it doesn't matter.

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

I had a cancelled flight because of technical issues going to my destination, and a delayed flight coming home. All told it wasn’t a total bust.

Seats are uncomfortable. This has been a trend in the industry for decades. Trying to fit more seats on each plane to increase profits at the expense of the passenger.

Women boarding passengers at the gate was absolutely rude and disrespectful of passengers. The flight attendant was absolutely delightful! Smiling and connected with the passengers. So happy. The seats are cramped and uncomfortable but I guess that’s just the way it is Communication regarding flight was excellent

I understand stuff happens, but plane failures are likely due to lack of maintenance. Additionally, air conditioning wasn't working, no snack/drink service, no WiFi. Fortunately, the crew was communicative and light-hearted. United grabbed another plane and we were able to get to our destination.

I was supposed to be on business class at first class from Denver back to Miami due to weather changes. I missed my connection and it’s put on a flight to Fort Lauderdale. Instead of honoring my business class/1st class ticket, they put me in coach, but there were two first class seats open. I think it’s absolutely disgusting that I paid for first class $1300 ticket and they put me in economy and they had to open seats available and I have still not been refunded the difference. I ended up having to eat a snack box instead of the meal I was supposed to get and did not get home till 2 AM so I think that’s a little pathetic that I had to live off crackers for dinner And my poor dog ate some cheese and salami. Oh yes, apparently when they switched me to the new flight they forgot to mention I had a service dog

It was fine. The flight attendant appeared to be in a bad mood but everything was fine.

I am not an electronic savy. I don't know how to maneuver the APPS for services. Why can't I just buy food without the apps.

This was a short flight with no food. The attendants were great but the comfort was poor: just to cramped. The flight from Denver to Frankfort was excellent! Seating was roomier, food was good, service was good. This was a great experience.

Flight was ok. Unfortunately it was a Boeing 737, which is a cramped / tight airplane. I prefer the Airbus as they are a more comfortable flight experience.

It was awful ....my first time flying on it and I will NEVER fly it again ....everything about it was terrible .....most especially the flight attendants

I liked the turn-style feature at gate 209B at LAX. Very efficient process. The gate staff also made several, clearly directed announcements so I felt very informed.

I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.

Allowed me to chose my seat without extra charge (I purchased full-price ticket) and boarding was in group1. Didn't even serve water.

Every day about it was very different all the boarding pass where all wrong l miss flight no refund all crazy

Staff members pretty horrible when boarding. No care for customers

Long lines, rude staff, everything that's offered you have to pay for.

The flight attendence were extremely rude and I am disabled

I did not enjoy the trip home on Frontier for several reasons: there is too much cost besides the flight, which was more than I would normally pay, then having to pay for luggage, and carry-on, seat (if you want to reserve when booking) then you must pay over $3 for a can of soda, and $4 for a snack. A cup of water is free.

There were 3 leg for the trip and each leg was delayed by 90 minutes or more. The boarding process takes forever with people waiting on the jetway even though most folks do not have carry-on. The whole process is poorly managed.
