Communication about the delayed flight was poor. We were told to move gates three times but that was bad information. We went from gate 128 to gate 126 and then to gate 123 and back to gate 126. Communication about the delay was bad. Ended up being 1 1/2 hour late getting home.

I have roller bag with food and medication told me I couldn't bring on my 2nd flight today. 15 years flying with SW never an issue with that bag.

I have not flown Southwest in awhile and had a very pleasant experience. From ticketing to boarding to the flight. The flight left on time and landed ahead of schedule. It won't be so long next time!!

Everything went smoothly and we even arrived a little bit early.

Boarded on time but once we were ready for take off, the crew determined that, although every seat was taken, somehow someone was on the wrong flight. Delay, delay delay, announcements and ended up with one person checking EVERY ID against their passenger Manifest only to figure out it was a "clerical error." We departed 54 minutes late causing me to run in the St. Louis Airport to make my connection and lose the priority boarding spot I had paid for. Unnecessary delay.

Flight was delayed due to plane not passing inspection And one of the crew had to time out and we had to wait for another one A 3 hour delay

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

It was one and half hour late... Not sure if any other experience matters.

For my birthday trip this was my second time ever flying, this trip was the best.

Boarded the plane in Portland and sat on the tarmac for four hours before being given clearance to take off. Apparently a "scratch" was detected on the preflight inspection. This delay resulted in me missing my connection in Baltimore. I therefore had to stay overnight and then catch an early flight this morning, which resulted in my missing a mandatory class. I would like a refund / voucher to cover the cost of the missed flight. And additional voucher for the time spent on the plane in Portland would also be appreciated.

It was as good as it could be. Flying is not a pleasant experience these days.

The plane was old and thus the seats were not good. No cushion left whatsoever, and it all was a bit worn out.

We departed early and made up time in the air allowing us to arrive 30 minutes early. Capt was incredibly genuine and thanked every passenger for flying with Delta. Completely humble and professional!

The boarding process needs to be refined. Sometimes the gate crew calls out the zones and then flip to showing the.zones boarding on the gate monitor display. So, unless you are huddled around the gate lanes watching the monitor, you could miss your boarding zone. Suggest the zones be announced each time a new zone is allowed to board.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

On 2 different flights the wifi was horrible and there was no drink or snack service.

Delta did an awful job w logistics at DTW. Missed connection. We were there an hour early. SUCKED

There was no FREE wi-fi nor entertainment screens at all.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

As we lined up to board they gave our plane to a flight going to Newark. So then we got delayed until they could find another plane. Flight crew was ok. I’m assuming since it’s a shorter flight they only offered water and coffee.

Crew was amazing, takeoff wonderful. The bathroom was disgusting from before takeoff the odor made the flight uncomfortable as you could smell the bathroom from the center of the plane where we were sitting. Smelled like raw sewage. My daughter was throwing up as we landed due to the smell and horrible turbulence as we approached Newark.

Both my flight where delayed Had 25min to make it to my transfer flight

Airport terminal was outdated, flight was on a small jet with no wifi

Essy to get on. The hostess gave very little pop, the plane was late getting in, and we are still waiting for our bags. This sucks. :/

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

Short flight - no food understandable. Flight was delayed for over an hour. Overall, it was good.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

We boarded and buckled and then deplaned due to no pilot. Had to wait over 3 hours for a new pilot. Not weather related, just poor management.

Last minute gate change nearly caused us to miss our flight. Change was not announced or displayed in the main board at the old gate. Terrible communication. When we landed we had to wait 20 minutes because there was another plane at the assigned gate. Not the crew’s fault, but adding 20 minutes to a 45 minute flight sucked.

Flight was 3 hours delayed. They gave our plan to two other routes. Need to knock that off.

We called Kayak for a change due to the TSA situation in Atlanta. What we got was a canceled return flight (in error) and we had to find the mistake. Not happy with Kayak who blamed it on AA.

Small plane, poor meal choices for first class, bad terminal and boarding experience at LAX

Boarding delayed 20 minutes for no reason, no wifi, in flight entertainment, or snacks / waters?

This flight captain and crew were amazing, started ahead of time of departure and reached 30 mins before arrival time. Amazing!

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Improvements in communication and empathy are absolutely necessary for American Airlines staff (top down). It’s like they are numb to the needs of their customers.

I had a TERRIBLE experience with the AA crew. I believe it was disability-related. It’s unlikely I will fly AA again.

Flight was delayed after boarding and no idea when it would take off. Crew in Portland did arrange for transport to Boston for a different set of flights to my destination.

Seats are so close together. Middle seats should be discounted.
