bulkhead seat had very little legroom - even in bsiness class.

bulkhead seat had very little legroom - even in bsiness class.

The plane was an older model, so it wasn’t as comfortable as others. The flight attendants were not helpful during onboarding. It was a full flight so there was chaos finding space for baggage.

Sorry I didn't realize I was writing a review for each leg. Please see my previous review - it applies to the entire flight, not just a single leg.

This is the first time I've been disappointed with Delta. I was called by Delta to see if I would volunteer to change flights since my original flight home was overbooked. I accepted. The modified booking only provided me a 35 minute layover - when you subtract the fact that boarding closes for a flight 15 minutes early, that gave me 20 minutes to run for one end of the airport to the other. I barely made it. On the 2.5 hour flight to Tampa, the crew repeatedly let us know over the intercom that they cannot serve drinks or snacks due to safety/turbulence. I would have accepted this reason if they did not CONTINUALLY SERVE DRINKS AND COOKED FOOD to First class. If safety is the excuse then the entire plane should be strapped in for safety. On top of this the air conditioning vents were not working correctly and the plane was uncomfortably warm. I love Delta and am a loyal Delta traveler, and I have never had an experience like this. I don't know if there's a disconnect between availability among third-party sites like KAYAK and the airlines or what, but when overbooking causes issues like this for travelers it should be reviewed and changes to the booking process should be made. I blame BOTH KAYAK and Delta for this terrible experience.

boarded at 5:30 pm, pushed away from gate at 6pm ... takeoff was not until ~6:45pm; disappointing

Smooth boarding, pleasant and professional lady checking us in. Crew service was excellent, again pleasant, but professional. Nice touch-down on landing! Thank you Delta. 💗

Originally, I was booked in economy. I paid several hundred additional dollars to upgrade to first class. Then I paid several more hundred dollars to change my flight to a slightly earlier flight. I asked if the changed flight would also seat me in first class, and I was told that it would. When I boarded the plane, however, I was seated in economy. So, I paid $500-600 more than I paid for my original ticket for an upgrade and a changed flight - received the changed flight (which was nice), but did not receive the upgrade. So, I was not completely satisfied.

Awesome! On time flight, early arrival, and a complimentary upgrade!

Paid for wifi that didn't work. No plug in seat to work. No entertainment.

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!

Both of my flights arrived early and check in process was smooth

Terrible. No customer service, no food, no drinks on a 6 hour premier economy booking.

Short flight, but no drink/snack service. The flights both going and coming were delayed.

Much better than Spirit. I was please by the easy fast check in and boarding

Check-in and in-flight staff were better than average. The seat was a fair size but too hard and not enough padding. The cushion/pillow provided is poor (thin and seems to be disposable ,it provides no effective cushioning or support). Food was OK-ish but no choice of inflight snacks and no easy place to get drinks other than water (I could ask for juice by intruding into the staff area at the back of the plane) Entertainment was very good actually. Overall better than I expected from a US-based airline (sorry!) but compared to ANA or Singapore it was so-so. (I live in Japan so they are my comparative airlines)

Everything was on time Will use united again for sure

Plane outlets in my row not working to charge phone. Staff response was, well it should be. Plug into seed for volume not working well. Had to find the sweet spot for plug in or it would shut off and on.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

Fine not above and beyond as I had a connection that was delayed due to maintenance

The power at the seat didn't work and the seat itself was difficult to adjust - this was a business class seat. Flight attendant gave me miles to compensate. The attendant was very professional and on top of his game the entire flight.

The seats are too uncomfortable for anyone over 5ft 8in. I'm 5'10" with a back and hip issue and I was in pai for the full duration of the flight.

The flight was on time/early, attentive crew, and everything overall went smoothly. Disappointed that WIFI was not working for the flight.

One day, I do so hope for a gluten free snack! Seems like with the rest of the world FINALLY figuring out what gluten free is, American Airlines would too. Fingers crossed!!

The flight was significantly delayed for 6.5 hours because of snow. There was no communication once the plane returned to the gate regarding when the flight would resume. Other flights were departing while our flight was being unloaded for reasons unknown. Our flight also seemed out of the queue regarding further deicing, refueling, and waiting to Taxi to the runway.

Flight was on time and the meal and service were good.

The accessible bathroom should be visible to people in Economy class.

Flight was delayed for 2 hours, then last minute the change to on time. The satélite location is far and a nightmare to get to.

This was a horrible experience. I’ve experienced several delays at this point and still not home. I was supposed to be home by 8:30 last night and here I sit at 7 am on a plane STILL unable to go home because of American Airlines.

Lexus in first class was absolutely amazing! Beat flight attendant i’ve ever seen.

Generally good. Flight left on time and the seats are comfortable. Plenty of space in front if you in you choose a comfort plus seat, completely worth spending the extra money given the amount of hours the flight lasts. The food tastes good but I would say it’s a the amount is too little. The crew was friendly and efficient. There was a some turbulence at different points into the flight. American Airlines has good deals to NZ if you book with plenty of time before you plan on going.

My flight was at 11:34am at February 4th don’t know the names of the crew, but they were the best, My first great flight. Loved it 😊🥰 Thank you!!

The entire experience was so surprisingly pleasant. And the blocked extra seat between us was such an amazing and nice bonus. Great experience all around and I can’t wait to fly with spirit again!

Horribly late because they had no crew!!! And then jet bridge didn’t work!! Then we arrived at a gate at lax miles away that we had to take a shuttle to a terminal!! I was over 3 hours late to getting the LA! Should have been here at 8:30 and at an appointment at 10:30 and arrived and left lax at 11 am!! Horrible experience!!!

Liked early boarding for disabled customers. Seat comfort could have been better, would have appreciated an empty seat between my wife and I since I suffer from arthritis, neuropathy, and spinal stenosis. Also aisle seat armrest was immobile and this made it difficult to get into and out of my seat during the flight

The airplane had a strange noise that was constant throughout the flight. Thankfully I had noise-cancelling over-ear headphones that muted much of it.

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 liked that the crew looked well put together. I also liked that there were little turbulences.

Absolutely horrible. Usually pay $40-$50 to check luggage in. I tried to check my suitcase in and the price is raised to $70. That's ridiculously greedy c'mon. I had to leave my suitcase with all my clothes and hygiene products and repurchase once i landed in Atlanta. You guys make it really stressful to travel. Don't even want to travel anymore.

I was never aware that I had to pay $100 per luggage to them on the plane that are simply carry-ons. This is discriminatory and I’m going to be alerting my entire family and friends and my Instagram following up over 75,000 of this issue and misunderstanding, including mismanaging.

Delayed due to no pilot. Per FAA policy I do believe we are to be reimbursed.

First of all we hade waited 3 hours in the airplane waiting to leave. Second the return schedule was changed and it messed up my entire vaction. I won't buy never again another flight and recommend to nobody traveling with them.

There was no food and no entertainment, so I'm not sure why these are even in the survey, as my understanding is frontier does not ever offer food without a few, not even a snack, and there are no screens so unless the flight safety talk is our entertainment why ask how we liked it?. One of the flight attendants say in the back of the plane as people filed in to their seats, yelling orders about where to put baggage and telling people to hurry up. It was the least professional experience I've ever had on a flight.

Very well recently! Frontier is improving and less harrassing customer on luggages! Positive!

Good for a budget airline! It was easy to get on, staff was really nice. Can’t say anything about the food or entertainment because it wasn’t available, which is fine.

I am writing to express my disappointment with my recent Frontier Airlines flight. I was charged $99 at the gate because my bag was said to be too large, yet once onboard there was no available overhead bin space, and I was required to place the bag under the seat in front of me anyway. This made the charge feel unnecessary and unfair. Additionally, before the flight even took off, I was asked to move from the seat I paid for into a middle seat so another passenger and her cat could have my seat to themselves. I was not offered compensation or an explanation for being moved from a paid seat. Between the unexpected bag fee and being forced to give up my seat, this experience fell well below acceptable customer service standards. I would appreciate a review of this situation and appropriate compensation.

It was costly and difficult to check in. $85 to take a small suitcase with me, carry on or checked and $75 on the return trip, Plus $25 if I didn't check my self in check in $25, because I couldn't do it on the kiosk. Small very uncomfortable seats, waited on the runway for near an hour each way. It was my worst flight to date.

It was ok. It was expensive to check 2 bags ($75.00 per bag), and then it took a long time to wait for shuttle to take us from one terminal to the terminal where the plane was taking off at LAX. And all of this for a flight where we had to pay for any food or drink that was not water.

It didn’t happen. I booked it and then was told it wasn’t available and then forced to pay far higher prices for a worse option

A 630departure flight Delayed 6hours! They changed my gate, I moved to the new gate. Had our flight on the screen for 12noon departure. I go get above to eat, check screen again and the flight was gone, no notice no announcement, nothing!! They sent my bag on the flight I wasn’t on, got it back to me 3days later. Thank goodness they did refund my money but I will NEVER fly them again.

Due to weather, my flight was delayed, further delayed, then canceled. I eventually got through to a support person who helped me find a different route out of MSP, but to get to DIA, they didn't want to, but eventually did help with the connection ticket purchase. But even this replacement flight was delayed time and time again, and I would have missed my connecting flights and I didn't want to get stuck in a layover city, so after 12 hours at the airport with two young boys who were very tired, we just cancelled our plans and spent the week at home, instead of Nana's.
