Enjoyed it very much. Especially liked the free WiFi that Delta offers.

Smooth flight. Left on time, and got in 15 minutes early. Onboard video was great

For some reason, TSA Atlanta didn’t have my bag on the flight on time and they don’t have to provide Delta a reason for that.

WiFi didn’t work on two of four planes. Flight attendants were not overly friendly or welcoming. Planes were extremely slow to board and deplane.

Delta does a great job with entertainment and free wifi. I can still be in touch with my colleagues while in the air.

Aside from a completely packed plane, I really have no complaints.

Bus to plane was delayed for no apparent reason and our luggage was still on the belt when they shut it off. Took about 20 minutes to turn it back on to get our luggage.

It was a pleasant surprise to have complimentary Wi-Fi on the flight

Much better than Latam, the worse airline company ever. I hope I don't have the need to fly Latam ever in my life again.

Seats in Delta Main are unbelievably close to the seat in front of. Hard to get a backpack under the seat.

Excellent service in Polaris class IAD to ZRH. Arrived rested and well fed after the overnight flight.

My flight time was changed without any notification to me which ruined my time sensitive plans so I ended up completely changing my travel plans and no reimbursement.

Excellent! I got to Munich and was transferred to my Lufthansa flight quickly, in 15 to 20 minutes, so I did not miss my flight. However, I had checked my overhead bag at the boarding gate in Tampa. That got to Tunis the next day. That is to be expected.

It's a short hop. My carryon was checked at the gate, I didn't have to drag it all over the airport. Excellent wheelchair assist.

WiFi didn’t exist , seats were super cramped, lights stayed on near my seat for a long time while others were dimmed, the food/trash/drink cart hit my shoulder at least a couple of times while moving, food options were down to just one option by the time it got to my row, the utensils were garbage (knife bent at a couple of places by the time I was done eating) the spoon was very flimsy plastic

Friendliest Flight Attendant I’ve seen since I flew on Southwest Airlines. The whole trip was outstanding…and arrived Early!

It was good overall except from Omaha to Denver when flight a was a repeatedly delayed apparently due to some issue at Denver. Communications could have been handled better. I had to board then deboard with luggage and board again

I didn’t have a seat assignment and my seat was very dirty on the flight from Frankfurt to Budapest.

Left an hour and a half after the listed time. Up side was it had TV screens on the seat.

No screens or meal options. Freezing cold. Dirty seats. Left late.

All airline travel outside of First or Business class is an ordeal to be endured. This trip was ok, small o, small k.

TV was broken and could not shut it off. The flicking was bother me and gave me a headache. The WiFi wouldn’t work correctly, I was able to text but not search the web or surf social media. The plane itself had a lot of wear and tear it is due for an update.

JetBlue not only has the most comfortable planes, but also used to have the best customer service. Lorie Wright, the lady at the gate was very rude not only to me, but to other passengers as well. Her colleague, the gentleman was also not very friendly. They both were acting like they were doing passengers a favor. The crew on board was very nice.

Flight was on time and smooth. Customer service was decent

The space between seat rows seemed to be larger than other airlines. I didn’t check their food or entertainment since I slept most of the way. They do seem to have a lot of options for purchase though.

Kayak sucked. You gave me a confirmation number that was not useable by the jet blue system. Nor did you send any check in emails. I’ll not be using your site again. Nice work.

Direct tv did not work on flight Short flight so no good service offered Arrived early to destination and had to wait for gate to open. Deplaned LATER than if we arrived on time!! Poor planning Jet blue has had something go wrong on every flight I’ve taken with them in last five years. Terribly run airline

Given us a free miles or free flight for waiting for 9 hours I didn’t get home till 5am in the morning and I was supposed to be home at 9:30 touch down.

Excellent price. Everything on time. two bad parts. Kayak said I couldn't sign in for the flight online, but I got an email at the same time from Jet Blue and they let me sign in online. Second bad part was that, although I had provided my known traveler number, neither of my boarding passes, for this flight and the previous one, had TSA pre-check showing.

Jet blue was great But the Jayak system Wasa pure nightmare and wasted so much of my time and energy by not giving me a way to access jet blue to check in the flight back I didn’t even get the number confirmation code 24 hours before. Because I didn’t receive the email with the confirmation code I could NoT CHECk IN. I spoke to a kayak third party and they informed me I could not carry a carry on, on the flight which caused me so much extra stress it was just too much. You can be sure I will not be using it recommending your site. Again.

Fine. Nothing to write home about. The plane left on time, and arrived on time.

I was downgraded from first class to coach due to an airplane change. They pulled me out of line and I was the very last person to board the plane stuck in the middle seat with no overhead place to put my carry-.on. Very poor customer service.

Seat comfort was poor (no lumbar or lower back support).

The airplane seats were spacious and comfortable, and the flight attendants were friendly and attentive. The food was delicious like never before. The blankets and toiletries were thoughtfully provided. The captain's navigation was steady and reliable. In short, having flown with Starlux, I won't consider any other airline next time.

STOP MAKING THE SEATING SO CRAMPED. WE NEED A PASSENGER BILL OF RIGHTS!

The passenger in front of of me reclined their seat back all the way the entire flight. Their headrest was in my face the entire flight! I barely had room for the little plastic cup of water to fit on my tray table; can you make the seats and space between the rows any smaller??? You can’t even get up to use the restroom! Worst flight I’ve had in a very long time!

We had several flights and they were all on-time and flawless

My Frequent Flyer nber wasn't put on as I was told it was..... This resulted in a last group boarding and no priority tags on My bags.

Premium Economy Good crew, good service, excellent food. Seat back screen just not bright enough.

Terrible steward... Plane was quite empty... I asked to move "back" in the plane and the steward said no... Unnecessary power trip of mediocre people.

They did not let us board because one member needed a transit visa, which was not evident at the time of ticket purchase.

I was charge a baggage checking fee $68!! I volunteered to check my duffle bag which usually goes under my seat!

I did not like anything because the flight was cancelled yesterday and I did not get to arrive on time in Toronto as I was rebooked with another airline. This caused me to be really stressed out as I am an individual with back injury and to be forced to stay longer in an airport to accommodate a change of airline and the transfers associated with it Due to this I am probably not going to book through your website to eliminate this potentially chaos in the future

shittiest airline in the hemisphere. To improve - start thinking you're flying people, not cattle

Easy boarding, inflight refreshments came on time and comfortable seat

It was good that our flight left early. It was a nice smooth flight and landing.

All good……but luggage didn’t make it on the airplane. Had to wait 3 days. Was a bummer.

Small suitcase used for carryon the last time was refused by boarding crew this time. Appears to be at the discretion and mood of the person on the day. Flight was only half booked, there would have been no problem with space.

It was a problem because there was a delay where we sat before taking off from newark,then when landed in Toronto we sat on tarmac and they wouldn't let us out for a long period of time. When we finally were released to the airport in Toronto the attendant scanned our boarding pass that we were here for our connection to Brazil. We ran all the way to the gate and they said at the gate the door is shut so we can not let you on the plane. We explained that we were checked in by the attendant when we arrived at Toronto airport to go to Brazil and they should not have shut the door. We were ignored at the gate

Flight home was delayed multiple times, did not get home until 2am
