Great flight but super high price. Glad it was a business trip and not personal

Great flight but super high price. Glad it was a business trip and not personal

On time. Friendly staff. Took to long to pre bord all the specialty groups. Cramped small plane

The seats were comfortable, and the boarding process was pretty smooth.

3 hour delay. Had to change plans and was still delayed.

No delays and arrived to destination 30 min early. Staff was super friendly.

Everything a cheap airline should be at normal airline rates.

Full cans of soda would be nice. A choice between two snacks would be appreciated.

Tried watching free movie and it kept freezing so I couldn’t finish.

I was re-booked onto another flight because my original flight was delayed and I would have missed my connector. I ended up in the “C” group after paying extra to be in the “A “ group on the original flight. At least if you’re going to re-book people, re-book them into the same group.

Was good. I miss the free 2 checked bags. That was part of what made Southwest special

There was no wifi available on this flight. And there were no screens, no onboard entertainment, no entertainment options at all. It was like travelling in the 1990s again, except without even a main screen for options. Seats, as usual, were tight and uncomfortable.

Good seat comfort ORF to ATL. Bad seat ATL to SEA (terrible lumbar support, hard, ouch)..

Because I was moved to an exit row, the snacks in economy comfort, the selection of snacks was better.

I upgraded to first. Quick and easy boarding. Comfortable seat with power and a nice IPA.

Probably not the fault of Delta but there was delay after delay after delay and I ended up getting home 4 hours later then I should have at 1:30 in the morning

No in flight service, no explanation - FC got service, C+ did not, unsure about Economy. No turbulence to speak of, so I guess another way to cut cost, or promote health and well being of Delta employees? Also, boarding in MEM combined zones, and with overhead space already full on both flights after Zone 2/ Diamond, presents a huge challenge to find a space for a bag. Delta, other than point A to B, is no longer reasonable to fly - very poor experiences, not even taking into account the chastising at the gate and rude crews, across the board.

It would have been better if the flight wasn't delayed by 2.5 hours

Delta’s staff is unmatched. From the gate agents, to the pilots, to the flight attendants… all top of the industry.

Delta flight Delay for ,more that two hours i.e original flight was 6.30 PM and it starts at 8.45 PM, When we connect Delta team for meal vouchers as it is late arrival in designation,But we did not get it as per delta policy , which is not good for mid night arrival,

Inexperienced boarding crew allowed too many bags on to a full flight and delayed takeoff causing a missed connection and unplanned overnight stay. There was a hotel at the airport but Delta would not pay for it offering only to shuttle me to an area hotel. Never even offerred so much as an apology by anyone working for Delta.

Delayed, toilets did not flush, pilot parked to far away from Gate

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

United is an incompetent airline. They parked the plane on the tarmac for an hour after arriving because they “didn’t have a gate available” it was actually some sort of lie because as we de planed there were approximately 9 open and manned and empty gates that we walked past. Many people on the flight missed connections for the hour long sit on the tarmac. Utterly baffling and incompetent behavior from United flight ops.

I boarded flight UA#1318 at Sacramento International Airport going back to Houston TX. The flight was scheduled at 5:10am. I was able to check in virtually using the United Airlines app. When I entered the airport, there was no one outside assisting with checked bags as it was for Delta Airlines. Immediately upon entering, there was a LONG, EXTREMELY LONG line to the kiosks to get boarding passes. I stand in line to get boarding passes then had to move to ANOTHER EXTREMELY LONG line to get my bags checked in. While standing in this line, we noticed an agent taking customers to 3 at a time to her station to check their bags in. Lucky for me, she called me back, checked my bags for me and I was on my way. I then encountered another long line at the TSA check and to avoid I ending up having to sign up for CLEAR to bypass it. So glad, I did.,...Both of my flights were great with no issues, butthe check in progress at Bush Airport was so much smoother. Check-in at SMF airport needs to be anaylzed and corrected. Do better United, I know you can....thanks

Ot was overall fine. Left on time and had basic snacks. Weather was finicky but that’s not the airlines fault.

Even though we were delayed, we were able to make our connection

Crew and customer service were excellent. This flight also had plenty of leg room and seat mounted screens for entertainment. A very pleasant flight all around!

I was in first class. The outlets at my seat did not work. The plane was shabby and run down. I had prepurchsed a day subscription for internet that was not redeemable. I had to repurchase the internet for my flight and then it didn’t work anyway. Quite disappointed in what was supposed to be the launch of a great vacation.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

They made me pay $40 to check a bag that was listed as free when I bought my ticket. Then before boarding they offered to check any bags free.

The seats from lax to DFW was so tight that I could not move my legs . No WiFi and had to pay . Not a good selection of entertainment

The flight was good. We had to spend almost an hour on the tarmac when we arrived in Dallas. Waiting for a gate. What’s the point of arriving early if you have no gate to park at?

Lower WiFi prices; allow us to see our flight on a map; more variety of drink choices.

Kayak was among the missing. There was not the usual advice regarding next gate after arriving in Dallas. No communication after the reminder to check in before the Moline flight. What happened?

They should have allowed for extra time to de-ice the plane before boarding passengers. This delayed us about 10-15 mins after we boarded. Overall experience was fine. Crew was friendly and on top of everything. We didn’t have any issues during the flight.

Our flight from Eagle to Vail was delayed to the point we missed our connection to Savannah. Now we’re a family of 4 in a hotel room with luggage, no toiletries, no clean clothes. Gate attendant said the delay was mechanical but it was put in the system as something else so no compensation. That’s just wrong.

I take this flight about 6-8 times per year. It is convenient and saves an hour or two by skipping PDX, SEA, PHX, or ORD (but it takes longer to get bags to the carousel than Alaska Airlines). I wish the food service were better (but they might cut back on it because it is a red-eye). The WifI seems to go down about an hour out of Anchorage, and then comes back about an hour later...so be warned if this is an issue for you.

WiFi didn’t work the entire flight. Very disappointing. Minimal food and options - sadly the state of current affairs. All other aspects of the flight were fine.

For whatever reason, the flight was not catered -we were told it would be a 45 minute delay waiting for catering - so no food. There were opened candy and peanuts in the seatback pocket. Flight landed early in DFW but due to the assigned gate not being available, we sat on the ground for 30 minutes waiting for the gate to open - making the flight actually arrive at the gate late.

Horrible experience. First and last time using this airline. Made an announcement that boarding will start in 15 minutes, canceled the flight 5 minutes later due to no airline staff. Had to book another flight on Delta since Spirit had no other flights arriving to my original destination the same day. I wouldn't recommend anyone to fly with Spirit. No wonder why it consistently ranks high among worst airlines.

The plane was supposed to leave at 12:59 Amma and another plane took us around 9:30 am. There were 7 delay announcements. We were to receive a voucher of $12 back to pay for food at any place in the airport. One passenger tried to use the voucher was denied. I did not receive the voucher for me, my son, and grandson. I went to the desk and informed them and they took my phone # and email and they told me to wait. I did and was never sent. The plane was uncomfortable, the crew was dismissive of anyone beyond the last two seats. I will NEVER fly or recommend Spirit Airlines again.

I knew what I was getting into, but never again. Hour long bag drop. 1.5 hour delay. 1 hr 45 mins sitting on the tarmac after landing. They lost a bunch of bags but luckily not mine. Awful experience.

Our flight got rescheduled 48 hours later, the airline didn’t pay a penny for our expenses.

Uncomfortable seats and tiny tray table. Expensive snacks. Flight was on time and crew was pleasant but take me back to Southwest!

Boarding and unboarding processes were pretty smooth. I gave a low score for Boarding because of how my flight was missing from all the boards at the airport, and when I checked the flight status on the Spirit website, it said it would be departing from Terminal E, gate D15. There are no "D" gates in terminal E.

The flight was on time and the crew was very professional and accommodating. When other airlines are canceling flights Spirit is still flying with on time flights. I have no complaints and will continue to choose Spirit when it is the best option for me.

Prices for bags are extremely expensive and if you go higher on weight, the charge is ridiculous.

Waited at the airport for over 4 hours to board this flight. Terrible airline

They specifically ignored a luggage tag I had for a dialysis machine. It's a life saving machine that they tossed on the baggage carousel, damaging the suitcase and almost breaking the machine. The crew promised me it would come to me at the gate and they ignored it.
