Indigo airlines is terrible. Staff is awful and so disorganized. They are so rude and unhelpful. I will never travel on Indigo airlines again!!!!!

I felt that when I was rerouted it should have been to business class.

The flight was smooth Thank God but the delays and changing gates for 3-4 times made me so tired of walking back and forth with heavy bags I thought I was going to pass out with heavy headaches but Thank God finally found the final gate and home safe. These delays happen anytime for important reasons so just be patient when you come across these situations.

Worse fight I ever take since I start flying , still have even made home , and crew abandon us half way home . No water no food and no even anyone to answer our questions

The Achilles heel of the experience with Qatar Airways is the Doha Airport, especially for travellers arriving into Doha and not transiting. This airport suffers from being ambitiously big and the immigration into Qatar being overly time taking. At the end of my particular flight in which my travel was ending in Doha, the plane parked at a very remote terminal, from where it took me 30 minutes to arrive just at the immigration counter, with fast paced walking and the time on a train inside the airport. Then, at the immigration counter it takes up to a minute or more to process each tourist visitor,due to time taking face and finger scanning processes and langugage barriers if there are questions or information to be exchanged verbally with the officers. If several planes have landed at the same time, it is not unusual that one has to wait 45 to 60 minutes in the immigration queue. In short, the frustration of arriving at Doha takes away all positive vibe of the airline, as the airline and the airport are heavily intertwined and are marketed together.

This trip was the most comfortable one I have ever experienced, the team was excellent and very helpful. I am so glad I picked Qatar Airways.

The space was tight, hardly any leg room and the crew surprisingly were busy and did not take the time to attend to passengers, felt rushed. There was a delay for check in since the systems were down the airport staffs were accommodating

My experience with Qatar airway was very unsatisfactory. They lost my child’s stroller and I was told they found it and will send it to the hotel which was a lie. I had to go back to the airport baggage claim and pick up myself after trying to contact them many times!. There was a lack professional and communication. I am very disappointed in Qatar airway and will not be recommending them to friends and family nor will I be flying with them in the future.

The food is not good and also if you ask crew to bring something they say ok I will bring but you will never get it. Please they should listen good to passengers

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

The economy seat was so uncomfortable, had not enough leg room for 13 hours flight, front seat basket was broken and couldn’t hold anything, food quality was horrible( we got food poisoned ) we charged for logged which used to be free. We paid too much for this flight and very disappointed. Turkish air line better to make satisfy and respect people instead of find different way to scam people.

With a 4 hour delay its was a very basic flight which was just bearable. We were offered food vouchers for the delay and then they didnt work, so that was annoying. Also poor communication about the delay which got pushed out 3 times.

I hate to have pay for my first luggage 165$ when I did my search on Kayak with 2 luggages .I don't plan to use kayak in the future and go with Turkish airlines directly

The security at the airport was excellent. The one criticism is the boarding process just before entering the plane. There were only 2 boarding lines and there were no barriers thus leading to a mass rush to enter the plane. I suggest that they board by rows, eight or ten rows at a time to prevent the mass rush to enter the plane. Otherwise, I would highly recommend Turkish Airlines

I liked everything: the work of the flight attendants, the work of the crew, the frequency on the plane and in the toilet.

Light and recline did not work on my seat. Very uncomfortable and could not read in the dark

for the second time disappointed with TK, they like JAT = joke about time

Very punctual, the onboard staff was friendly and correct, the flight was fortunately very calm, the toilets were clean, in short, an excellent experience Thanks

Both my luggages were never sent from Istanbul. After 10 hour flight from DC to Turkey and another 12 hour layover in Istanbul Airport, I would’ve at least expected to find my luggages when I arrived in Addis Ababa, but that wasn’t the case. After 2 hours of waiting at the luggage carousel, we were told that our luggages would be arriving the next day after midnight. I was already so exhausted, that I hated having to come back to the airport the next day. Thankfully, I received both my luggages the following day. It’s just, the whole experience was exhausting.

Flight Singapore - Istanbul was perfect. Flight Istanbul - Sao Paolo - Buenos Aires was really good but there was a big delay in Sao Paolo (Brazil) due to a problem with the ground staff and not related to Turkish Airline. Overall a very good and solid experience
