Flight was delayed multiple time and for more than 1 hr. My onward flight from BOS to MCI was also delayed. These delays have caused me so much inconvenience and Delta does nothing to ensure flights take off on time. No one knew why the inbound flight was delayed and what was the issue.

Our flight was delayed by over 4 hours due to a maintenance issue. They announced a new plane was on the way. We were given a $12 food voucher ( airport food is quite expensive You can’t even by a water and a small snack for 12:00. 4 hours later we boarded and landed in Atlanta at 10:20 ish pm. Of course we missed our connection and we were given a hotel voucher and another food voucher ! We didn’t make it home until 11:00 the next day ! Unacceptable

From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.

Delta has too many delays now days. It is 1:06 am now. I was supposed to land in Norfolk at 10:30 pm. I got re-booked through Detroit and I’m still in Detroit. I hope to be landed in Norfolk by 3am. I’ve been in airports for 12 hours as of right now. There is a weather delay now but most delays lately have been maintenance.

Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!

My flight was canceled after being rescheduled for four days canceling my trip. Kayak and everyone affiliated with it I.e the airlines, and just fly have been excruciating to deal with. My trip to visit family had to be canceled as there was no way to make it. I am furious at all of you.

They delayed our flight because of bad weather in NY which was completely understandable. Then they cancelled our flight and a later flight that evening. The earliest we could fly was the next morning. We ended up buying last minute tickets on another airline and made it home slightly delayed but safely that evening. Delta kept saying it was weather related but if that was the case how did we make it back on another airline? The weather in NY was cloudy but not bad.

The plane smelled like a sewer. Multiple passengers complained. It’s a safety and quality issue to clean these planes.

We were delayed 2 hours leaving STL. I had 20 mins from when we landed in SLC terminal A to make it to SLC terminal B. I had to actually run! thankfully I made my flight but 3/4 legs were delayed to some capacity.

Looks like a local flight. Food was horrible. No entertainment system.

Economy travel is really hard with no room to move especially when the person sitting beside you is an XL or XXL size person who if moving could hit your face

I purchased Qatar airways after seeing ads about its service. To my surprise Qatar is marketing gimmick and horrible airlines which I don’t recommend to anyone Flight was dirty including flight from Miami to Doha And Doha airport restrooms are dirty On top of this they use this pathetic cheap indigo From Doha to Hyderabad which I will never fly Also they lost one of my baggage in Indigo and still waiting to receive it. I will never travel Qatar and will never recommend

There was not enough staff during boarding which had created big problems . Another thing once you enter gate area there’s no way to use bathroom and you have to be in that area 2 hours before boarding which is too much.

I would advice everybody not to fly by Indigo, no entertainment in flight, rude behavior of staff, worst experience of my life

Flight could have been better. Sandwiches provided in the meal were inedible. Service was pathetic

Ordinary Indian food... Not great. Limited movie and TV selection

Each and every requirement was nicely provided by all staff no very be happy

Qatar said few times that the luggage will be at the final destination but they were wrong. Please check where your port of entry is at the destination. This is where the luggage would be. The food was terrible.

We were stranded in bus for 10 min waiting for baording..Specially when you are traveling with kids and long previous flight. Flight has no information regarding time to destination. Wish to have screen for international travels.

Good but I don’t received my bags yet is been 5days still no update

Congested seating area Toronto Poor announcements Terrible food in flight Limited entertainment options

Flight cancelled. Major disruption to our travel. Do not use Air Canada from KC. To few flights.

Friendlier staff who are nice to the elderly who need assistance

Service was great. Flight was delayed an hour which made our connection very tight and stressful. But we fortunately made it.

There was a mistake with the first name we only discovered at security. Air canada was unable to correct it to match then passport since it was booked through an agency. The agency could not correct it either since they need at least two hours to do that. We could not fly and lost a bunch of money. Learned my lesson about kayak.

Fresh fuit or veg snacks would be so great, but there are two good restaurants in Denver airport. Try Etais UDIS or Freshens DIA for nutritious delicious pita sandwiches/ donairs and crepes in Freshens.

I appreciate the fact that the flight took off and landed on time What I didn’t like they never offer a snack eg nuts/cookies/chips

The flight took off an hour late but no update was provided on why it was delayed and what is the expected take off time.

Air Canada seems to be understaffed which caused delays at every point of the flight—delays at departure, delays in the air (circling), delay after landing, delays at the gate before disembarking. Horrible experience. And my son, who departed Toronto today, experienced delays because the passport scanning system was down and was told that he would not be able to board his flight. Toronto airport is a mess!!!!

Very friendly, service oriented and responsive crew. Very pleased with th service!

Very disappointed. None of the bags from Newark & Toronto flight were loaded onto connecting flight to Mumbai. And yet, no announcement during the flight. No placard near the luggage carousel in Mumbai. Absolute mayhem at Lufthansa lost & found counter. Each agent taking 20 minutes to record each incident. Stood in line for more than 1 hour, after suffering through a 8 hour flight.

This flight was operated by Air India and it was good experience

Food was good, flight is old, no leg room and restrooms are downstairs not easy for elderly people

Great, wonderful crew, comfortable flight. I had an excellent experience!

Plane was bit old and sits were cramped. But flights crews did an amazing job to take care of us. I would consider Lufthansa again just for them.

Airport facilities poor. Misleading information about the airport where boarding was to take place.

Flight got struck in gate for 45 mins for no reason. Flight got delayed reaching Mumbai causing lot of discomfort

Usually a business class traveller had to do economy this time due to last min travels and no business class ticket available The staff treats u like substandard citizens . Especially to coloured ppl . This would not have been the case if I were back in business or first At Munich I asked if there was an option of upgrade and not for free I would pay but within 30 sec she said the flight is full ..the interesting part is I did not even tell her which segment I am.flying . But seems like she was not interested in talking

Treating basic economy customers like untouchable and giving worst services just because we bought that ticket is ridiculous! We were not given option to choose the seat even at the time of checkin, we had to request the boarding staff at the gate as me and my wife were given different seats. She did not have seats together after letting us know rudely that they are not supposed to give any services to basic economy customers. Even bag purchase charges were extremely high!!

A little bit late but it went smoothly overall. Delicious food on Indigo!

Overall, the food and entertainment were great. The staff were amazing, polite and professional. They did not have WiFi on board on this leg but that was okay. There was a delay in boarding from London and landing at Mumbai airport but the pilot communicate DC the reason for the delayed landing. They even sent us an apology afterwards for the delayed landing.

Nice experience. Baggage arrival in Mumbai wasn't that quick and needs improvement.

Need a do not disturb sign if you wish not to have any meals so that they can wake you or have the meals served . Left very sad and hungry .

Our flight from ORD was cancelled and BA rebooked is on a flight that originated before the time that they booked us on it. They did not realize we were already arrived in Chicago. Then American Airlines helped us get checked in to the new flight (the one BA assigned to us) which flight we did take although it was delayed about 2 hours, and our assigned seats that we paid for - on the original flight- were lost we did at least get to sit together. It was not too painful for all the changes and we made it to the UK alright though all in all with all the delays and cancellations the flight took about 20 hours to get us here.

though there was space in the cabin they asked us to check in our trolleys. As a result lots of things arrived damaged in Larnaca. They were fragile. When we asked the attendants why that.....they said talk to the captain!!! Unbelievable!

Luggage handling an response received on lost Luggage, was pathetic

No food as per my diet restrictions even after advance request and delayed baggage without any notifications

It was a good experience. Flight was good, service was good, staff was good. But no charging ports in the first flight and in second flight there was a charging port but it was not working, so couldn’t use it. Need to improve in that field. Now a days it is very important. My TV was not working and then I couldn’t use my phone because of no charging.

For the amount of money charged, it was ludicrous (actually quite insulting) that they used such an old plane for a prime long haul route. Food was terrible. Entertainment was a joke. Time travelled back to the 90s with a 7 once screen and 3 ridiculous options for a hindi movie. The staff was the only saving grace. They were extremely helpful. I will give this route one more shot with BA - if it stays this way, I reckon we'll fly with some other airline. Lots of others saying the same thing as we were all chatting after getting off the flight.
