The WiFi has been awful on my last few Delta Air Lines flights.

10.0 ExcellentCarolyn, Oct 2024JFK - CVG
Read more Delta reviews

The WiFi has been awful on my last few Delta Air Lines flights.

Only one side of the heafphone jack work. Crew was friendly and helpful.

Typical flying experience in the US. Nothing particularly good or bad.

I was able to select a gluten free meal for my outbound flight operated by KLM but my selection wasn’t saved on Delta so I ended up not having a hot meal. The cabin crew was nice enough to offer some cheese so I could pair it with some gf crackers I had. The seat would recline but slowly but surely would come back up so I couldn’t sleep as I would have wanted to.

Forced to check my bag which fit in carry on, boarded and then sat for over an hour waiting to take off with no explanation.

7 hour delay for mechanical reasons Handled badly by crew and delta personnel

It was reported to the passengers that Delta failed to schedule the crew properly. This error caused the pilot to show up about 30 minutes late. All in all Delta's inability to take care of this basic function resulted in about an hour delay.

Food was not the best. Too many items had sauce pm them with a lot of spices The seat was not comfortable especially when you lay down

Don't need the male flight attended lecturing. The whole plane on how to act when there was no problems.Other than that everything was great

Loyal Delta traveler, but last nights flight was a train wreck. Seated in 1B after multiple delays. Then we couldn’t takeoff because of an issue with the passenger that was ‘not in compliance’ and had to deplane along with the threat if they did not deplane, all the passengers would be required to do so. Finally they were escorted off, but the experience threw off the crew. Disruptive for everyone. Service was a mess, televisions didn’t work, bathroom door kept swinging open during the entire flight whenever empty …

I tried to upgrade to premium economy anis seat online during the checkin process. The payment didn’t work due to a technical glitch on KLM’s website. I wasn’t able to change my seat unless I called Amsterdam. Since I was in Canada and there’s a time difference this wasn’t practical. So when I arrived early to Ottawa airport my seat wasn’t available and I could only get a middle seat in premium economy which isn’t great. These middle seats are priced at the same rate as an aisle seat which makes no sense.

Seats were comfortable crew members support was very good but AVML ordered or selected by us needs a lot of improvement.

Transavia flight, was booked as KLM but i couldnt select seat or access boarding pass with KLM at all. Crammed seating and very no frills experience all around. First and last time.

Transavia flight. Couldn't select seat or anything prior to flight. No connection with klm systems. Seats are very crammed. Extremely no frills.

Overall a very pleasant flight. No significant issues on either flight. Amsterdam airport is very convenient for connecting

The IFE was quite old, but it worked fine and the content was good. The cabin crew were excellent and the food was as also very good

Great flight because I upgraded to Premium Comfort. Made a huge difference in the experience.

The baggage service at Malpensa was the worst ever. We wanted for over an hour without any information, they broke my suitcase, and the services of the local luggage services company was below any usual services level of a KLM partner.

Good experience, just i couldn’t connect me to the wifi

The flight was great, the only reason for middle scores on entertainment and food is that it was a short flight so not included (but snacks were served including alcoholic beverages free of charge). I would definitely recommend KLM.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

Overall good flight. The pilots were excellent. It was a nice flight, but the seats were a little uncomfortable.

There was no air on the plane and it was very hot.

Flight crew was amazing! I don't like that the Polaris seats are side-by-side.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

Flight was 3 1/2 hour delayed with no credit or meal vouchers

Smoothly flight, pleasant flight attendants. I wish there were better food choices.

Everything was awful Flight attendant was condescending, rude and not helpful at all. Small outdated plane. No service, uncomfortable seats. Flight attendant was really the worst. He used hand gestures to communicate instead of words and whenever he used words he was condescending.

They need to improve their boarding process. Group 1 and/or paying first class passengers shouldn't be in the middle of boarding process

late departure due to some unspecified issue with ventilating the cabin. They got it running but it was FREEZING for the whole flight. I asked for a blanket but they didn't provide one. They could not turn up the heat. it was quite miserable.

The boarding process was incredibly slow, as was deplaning. They started beverage service and there was an extremely small amount of turbulence, so they discontinued it. They said they’d resume if possible, but even thought the rest of the flight was perfectly smooth, they didn’t bother. Getting our checked bags took longer than I’ve ever waited and they couldn’t even tell us which carousel they were coming out on, so everyone was running back and forth for 30 minutes.

It was really good. The boarding was good and smooth. They even checked our carry ons if you wanted to without any charge.

Flight was delayed , waited in the tarmac for 3 hours and then came back and was cancelled

Extreme weather delays. Missed my flight to France and I ended up leaving the plane.

I arrived to LaGuardia Airport 50 minutes prior to my 6am flight but was told that I was too late and would have to flight standby to Dallas in order reach my final destination of Jackson, MS. Hundreds of people were in my situation but the agents chalked this up to being normal for any day. Had my been able to board my original flight I would have arrived at my destination by 10:30am. I didn’t arrive until 7:30pm which included a 30 minute wait on the tarmac. Strangely my luggage arrived at my final destination at 12:30pm of the same travel day. This was by far the worst travel experience I’ve ever had.

The food was horrible compared to other airlines, there was no space for the overhead bins for carry-on luggage, and the seats were very uncomfortable.

I got food poisoning - lasted 4 days after starting medications - someone should check with food delivery.

They were not helpful in letting my baby and I rebook a flight early in the day when it was clear we were going to miss my connection (we did). The seats are much smaller than I remember. I did not get the option to board early with my toddler. I was flying solo with her and that would have been a big help.

On an overnight flight people behind me kept lively and loud conversation, which meant I couldn’t sleep. Food was really lousy, im sorry to say.

I am very disappointed with american. We have flown American airlines numerous times, as well as other airlines and never had such an experience. My son's flight for Sunday afternoon was cancelled around 11 am. We were told not to do anything bec AA would. After an hour of not seeing a change in his flight status. I called AA. I was on hold for half hour then opted for a call back. That call back never came. So I called again, in meantime I started looking online at my options. No flights were leaving that day from AA. But other airlines were flying out. We needed our son in Chicago asap.i kept calling AA for a callback, but never received one. Finally i called back later in the afternoon and a representative answered the call. She told me there were no flights out till Tuesday morning. I asked how this is possible, I had seen flights from AA and other airlines leaving Monday. She said she checked all NYC airports and there were no AA flights till Tuesday AM. Then I asked about getting on another airline. She responded i would be responsible for that. When I asked how AA would reimburse. She became nasty and told me AA has not responsibility to reimburse anything they will put me in a flight for Tuesday morning. When i explained he must be there Monday by 8am, she told me there's nothing to do and practically hung up. At that point I just asked her to book the Tuesday morning flight. I had this experience with other airlines, cancelled due to weather and they and their reps were much more helpful. Either way Tuesday morning flight was delayed as well. Over an hour! I expect more from AA.

No fast track available, no organisation. Unpleasant boarding system at gate 20 at JFK. When giving feedback to the lounge team I was told to talk to the manager instead of taking the feedback.

Flight attendant kept banging her cart into my aisle seat. Hard. Couldn’t lean seat back. Should be warned of limitations when booking seat

Lost our luggage going to Spain. Missed our connecting flight returning to home

It would be great to have at least two choices for a food, instead of just plain pasta 😏

Cabin crew were not nice. The plane was an hour late arriving.

Flight was on time. Boarding process was tedious. Not much overhead cabin space. Seats very close (front to back). Uneventful trip just the same.

Great staff, very personable, attentive. We had a spare seat next to us so that helped

The flight from Porto was delayed by 3 hours. Arrived in the US late at night. Exhausted from all the waiting. And staff did not communicate well with customers.

The crew will not help you with the overhead bin even if you are business class. If they do, there's always the sentence " we are not supposed to lift anything".... To charge for seat assignment in business class is nothing short of money grabbing/ ripoff. The ground service in London is better than Vancouver, which was atrocious.

It was purchased as British Airways but for some reason was Iberia ???
