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.

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!

Was forced to check in my small carry on, even though I informed the crew it has very fragile items inside

This was one of the worst flights I’ve been on in years. I upgraded to comfort and had such an uncomfortable experience. The person next to me was oversized - which I understand - however, they took up their space and mine. I could only use about 50% of my seat space to not be physically touching this person the entire flight and there was no spatial awareness. I also could not use the seat outlet because their body was obstructing it. It was very inconvenient. Their body kept touching me repeatedly during the flight and I felt very uncomfortable. To pay more for an upgraded space and then not even being able to use it was highly disappointing.

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 got delayed and eventually canceled, then rescheduled. I and several others had a connection from Boston to Paris and asked several times if we would make it. They assured us we would and then rebooked us mid flight without our consent and closed doors early even though they said they communicated we were a bit delayed. We got stranded in Boston and I opted with being rebooked for a different connection to France since they refused to pay for a Hotel. I've now been in Europe for 5 days and still haven't recieved my bags. There was absolutely no urgency for the fact that I'm in a foreign country with absolutely no change of clothes or any of my medication. Such an overwhelming and frustrating experience.

Automated scanning was slow and somewhat haphazard. Too many people were unfamiliar with the tech and were forced to learn on the fly. The hands off approach of the gate staff made it more uncomfortable. This needs work. Overall the flight and cabin crew were excellent.

The crew for the flight was A+ top notch. They were friendly and professional and made the flight a very relaxing and enjoable.

Rude crew member. She seemed annoyed at me without me saying a single word. Also loudly admonished me for having my bag next to my seat instead of tucked away before landing. Just telling me to put it away and guiding me without giving me a lecture would have been enough.

No included food for a 5 hour flight and the entertainment was only accessible if you had wired headphones (not provided). Otherwise though, great and smooth flying and customer service.

Crew were fantastic and so catering and wonderful! Full score for the entire crew!

Because of weather and mechanical issues our flight was 4 hours late. The only compensation offered to us was a meal voucher to be used only at Boston Airport and only on the day issued. But by the time it was offered to us all the restaurants were closed, so there was no way to use that offer.

Friendly crew, efficient boarding and flight arrived early. Couldn’t ask for a better experience

Terrible. They canceled our early morning flight after midnight on the day of and had no available flights to rebook my family on for the next 72 hours. Yet they still had other flights that were not cancelled from JFK so it couldn’t be based on the weather. It felt like they canceled the flight based on it not being profitable enough for them. I am not interested in traveling with the again. The absolute worse customer service and lack of accountability.

Horribly rude check in at airport, worst in 25 years of flying. All over a simple issue they could have googled to resolve.
