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.
