Southwest is Southwest. No frills. If you're luck enough to get a happy crew (we did), then it makes for a nicer flight.

Southwest is Southwest. No frills. If you're luck enough to get a happy crew (we did), then it makes for a nicer flight.

Southwest is typically delayed, and it gets wearisome. It is no longer a discount airline and you get way less than you pay for when it comes to comfort and Ce.

We sat on the plane on the tarmac for 4 hours.

I'm not a fan of Southwest's model. I don't like the herding style of boarding.

Flight crew and cabin crew were great. I had to rearrange flights because my original flight was 3hrs delayed for weather, the rub is the flight I moved to boarded on time then we sat at the gate for 2 hours because scheduling stole our first officer for another flight, TWICE. Then our actual FO was an hour delayed. To make it worse my original flight went from a 3 hour delay to departing 15min EARLY. Just poor scheduling operations all around.

Bring back peanuts Take our drink orders when were all seated, especially after you switch to assigned seating.

Staff was far less than helpful at all times. Departure and arrival times mean nothing to Southwest. Extremely disappointed, will never fly with them again, and I’ll be sure to share my experience with all.

It is southwest seat was ok. Not the most comfortable seat

I’ve always loved Southwest. No issues at all. I was flying standby and the gate agent was extremely friendly and helpful. Boarding was smooth and I was able to get a window seat in the emergency exit row. Crew was fantastic! They were very professional and accommodating. We had to divert from our destination due to weather but the flight crew kept everyone at ease and informed us of all pertinent information. Excellent flight

The price of the tickets isn't matching the flight experience. No matter how long the flight is, you're only getting pretzels. The flight attendants looked unkept and over it.

Loved the staff, boarding and drink options! Wish the comfort of the seat could have been better nevertheless

The chair cushions may need an upgrade. I have been noticing they are so worn out, thin so you’d sit in a dip 😄. Other than that, all was an enjoyable trip. Thanks AA!

I’m impressed that we were on time in Sacramento after having a late departure in Newark and our made it. The staff was friendly and warm.

Cramped seats. FAA should make airlines have more legroom, for even short people complain

5.5 hour delay with no explanation on why, along with no proactive effort to reaccomodate me.

It was one of my worst flight ever. First they were changing the gate for at least 4 times, changing from gate D7 to D12 to D44. Considering the size of the Miami Airport, we are talking about long distance and the train at the airport was not working. Then the flight was delayed around one hour. Then finally we boarded into the plane and when everybody was seated, there was an announcement that there is an issue with one of the tire of the plane, so we all had to get out of the plane with our belongings, to replace the tire. So we had around 2.5-hour delay

Most miserable flight ever. We waited almost 2 hours on the runway because the flight was oversold. American offered $1200 credit. Then there was some nonsense about weight distribution. Ridiculous. No food for 8 plus hours on the flight. I will be writing a letter.

Honestly, I haven’t flown American in years, probably due to the pandemic and my being unable to travel for certain periods in the last two years, but it was a good experience to dig out or obtain a new American Airlines account after many years of traveling for business with American in the past.

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

Plane, flight, crew, captain were all great. The first flight had a Chipotle box lunch...delicious.
