Worst experience I had on Southwest. Still better than most, but the seating was barely tolerable.
Worst experience I had on Southwest. Still better than most, but the seating was barely tolerable.
It was okay. The plane was delayed from earlier in the day, but they kept updating the departure time, sometimes later, sometimes earlier. That was stressful. Once we finally got on and took off, it was fine. I was supposed to have a connection in Chicago to Los Angeles, and the time for so late I was rebooked to arrive in LA 3 hours late. The departure time to Chicago later became early enough to have taken my original connection and arrive earlier but that wasn't an option.
Everything was on time. I was disappointed by the front section female, African American flight attendant. I did not see her name tag or would have identified by name not race. As passengers moved to the bathroom early in flight, she would say with a disdainful tone “I have to say the seat belt light is on” then go back to her book. Better trained flight attendants say something like be careful the seat belt light is on.
Flight was awfully bumpy and landing was a bit jolting. I was in the restroom when snacks and drinks were served and was not asked if i wanted any. I had to ask for water finally.
The movies using Southwest WiFi kept pausing and I had to restart multiple times.
This was a nicer flight - not fully booked and so we were able to spread out.
I like that it was on time and the staff was friendly.
A bit expensive for the overall service; but the flight departed on time and arrived early.
Board Milian spokesman with pre boarding , not after A group and without my spouse. Total BS, back to Alaska Airlibes I GO. oner 1.2M miles and 900 flights, and every time I fly SWA I regret it, thos will be last time, I only flew SWA but to time requirements fir a Funeral. NEVER AGAIN SWA
The crew was nice. Boarding sucked. Instead of loading from the back to the front people just sat wherever and you had to wait for them to move to get to a seat. And the flight was 25 minutes delayed.
Flight attendant in first class gave poor service (like he didn't want to be there) and food was awful. We sat waiting for gate upon arrival over 45 mins.
Weather delay in Chicago?. No sense of urgency to make connection in Chicago for our connecting flight that wasn't delayed. Connection was missed.
Overall it was good. I missed my connection but I was put on another flight.
Overall a very poor experience - booked premium economy tickets but due to last minute flight delays , all my itinery went for a toss and had to fly economy class with no access to lounge or any compensation by united airlines to make up for the flight delays . i had expected better experience than that from united.
It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.
I liked that the flight was nonstop from ORD to CIU for $200 round trip.
While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.
The first flight was better in terms of the aircraft.
Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.
Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint
Any flight to ORD after about 2pm this summer has been challenging. Flight was delayed getting in (coming from ORD) and that led to it not leaving before a ground stop due to lightening before they could fuel the plane, and so forth. They made up some time but we were still late in arriving at ORD, and that led to missed connections.
Food was ok, but not as good as I have had before on AA.
Pretty good. The food was just mediocre, the boarding and crew were good.
My flight got switched and my prepaid bag didnt transfer over properly so I paid to check ANOTHER BAG. I was placed in a middle seat and it was just miserable. At least it was a bulkhead row so I had legroom. The flight just never seem3d to end
Was not able to watch most shows on the entertainment site. They would not load
On Wednesday, July 30 we were in mid flight from Manchester to Charlotte and we turned around because the right engine was malfunctioning. That was the last flight out of Manchester that night. I was rebooked for Thursday, which became a weather event Friday. There were no seats left on the flight from Manchester to Charlotte. Consequently I didn’t leave Manchester until Saturday morning and we flew to Chicago so to say the least my scheduled flight and return to Iowa was three days off and it messed with my business schedule. Consequently cash flow. I would like some sort of acknowledgment of this event.
Dreadful experience. Our flight was delayed more than 8 hours due to a maintenance issue and the assistance from rebooking was poor. I was travelling with a bad knee and needed assistance waited in one place more than 3 hours before someone came with a wheelchair. The woman next to me was a 91 year old great grandmother who had waited more than 4 hours. There were moments of support from the staff but it appeared as they were going against the direction of management. It was apathy, lack of ownership and dismissive responses with small moments of kindness and understanding typically from grey haired, female, veteran staff..
Couldn’t get the door on the plane to close leading to a nearly 2 hour delay. But, hey at least they didn’t cancel the flight.
The flight was fine and the crew awesome. The problem is ORD and AA. Computers went down, ORD fell apart and a 40 min flight turned into a 3 hour trip. Guess the answer is to not try and fly to ORD after noon. But, as I said, crew was awesome and did everything they could to lesson the flight time.
The flight was fine but the 8 hour delay in Chicago was awful - 5 gate changes and repeated delays without an explanation. No vouchers. Nothing.
Late departure by 1:45min. No explanation why. During boarding inconsistent policing of their baggage rules. Before takeoff and lamdimg strange obsession with window shade and armrest positions. Don't know why they care. 15 min tarmac delay on arrival, they blamed airport congestion but we were the o lh flight waiting, it was clear it was due to poor staff planning (only one ground crew to receive airplanes and multiple arrivals) Got there but was rrally lame the whole trip.
One of worst experienc my family have every had with this airline. I was informed my Kayak that my flight was delayed and that my family will not make it to houston for our connecting flight. I contacted Spirit customer service to get my family on a later flight due to the delay in Vagas and them not making their connecting flight. The customer rep keep telling me that the flight from vagas is on time and not delayed. She even make to go to the spirit app on my phone and show me how to look up weather or not the flight was delayed. The app showed "on time" 20 minutes later when my family arrived at the airport for their flight, they were told that the flight was delayed and she will not make her connecting flight. I call spirit airline customer support again that night and spoke to another rep who apologize for his collegue and he told me that my family will receive a credit for this, this was on Saturday I still have not received the credit or an email letting me know when I will be credited for this inconvenience. This is not good business and it need to be fixed.
Flight was cancelled. No reason given. No apologies. Next available flight is two days later. Ruined our 4th of July plans.
Flight delayed over 3 or 4 hours because no captain to fly plane. I couldn’t make a connection and had to wait 9 hours for another flight. Had to fly red eye flight. Sucks
We paid for upgrade seats (3A & 3B) the seats on front and the seats behind us got complimentary water & soda, but we got charged, had to pay for everything. Does not make any sense ?
Horrible considering I didn’t go and I bought travel insurance and I didn’t receive a refund.
Spirit gets you there; it's no worse than any other aircraft, all things considered. (It's not like everyone else is such a hero). But - holy moses - do they nickel and dime you to absolutely every nickel - I was really expecting to have to pay to use the bathroom. And when the captain comes on with a 5 minute sales pitch about getting "points", that was like something on Bizarro world. Other than that, everyone else was professional and worked hard to get us from point A to point B. I'm not loving all the "self-service" stuff but there it is - just when the machines don't work you don't have anyone to talk to.
The ease of booking the flight was very good. Speaking with customer service was also good. However, the crew people are unfriendly and unwelcoming which I found this as unprofessional. As far as comfort it was mediocre. This was my first time flying Spirit and I chose them because of the flight times met my needs and my budget. However, I would be reluctant to fly on Spirit again. In addition, if the crew were more friendly and at least appeared somewhat happy and welcoming personally it would probably make the experience of flying with Spirit better.
hahaha we are delayed for one hour plus.. but thx we arrived San Diego safe
Canceled my flight and refused to put me on a different flight to get me to my destination. Unacceptable and ruined my trip
sluggish boarding and arrival procedures, fake nice flight attendants, and lots of delays.
Disaster. They lied every step of the way. We ended up being delayed due to crew and then allegedly abandoned the flight because of a curfew at LGA. No rebooking to LGA at any reasonable time. No hotel. No meal vouchers. Had to sleep in the airport and fly to Newark instead. Will never fly Frontier again.
What I expected, nickeled and dined and a frontier flight attendant loudly complained about her job and lack of communication as she headed to the gate on her cell phone. Not professional.
As every law enforcement agency I could imagine surrounded the plane and we didn’t disembark for 2 hours and then had to stick around for another hour to go get our personal belongings after leaving them behind and being bused away from the plane, it was scary and inconvenient. We were given no information as to why this was happening. Lack of communication with passengers was disappointing.
After boarding and un-boarding twice over 6+hours, the flight was canceled.
Severe turbulence. Captain never came on to reassure passengers after things settled down.
My first flight was delayed 5 hours. The 2nd flight was canceled til the next day and the never even tried to compensate for it. Worse I was delayed again on the flight the rebooked me on.
baggage clamed had to wait over a hour and half for all people on my flight it was terrible
Both legs of the flight were changed. The day of the flight and length of the trip.
First of all, we never got on the connecting flight to Denver. They delayed our flight for two hours. If we would have gotten on that flight, we would have been stuck in Denver for 13 hours. So we re- routed our flight for a straight through flight to Oklahoma two days later. THEN, they delayed that flight for two hours. After that we were able to finally get on our flight and come home. Frontier Airlines - one of the worst airlines I have ever been on.
