I lost my lock from my luggage, I don’t know someone took something from my bag.

Except for the uncleaned tray, and the delay in serving food for our section (which may have been due to the location of our row) everything else was good. The crew were very professional and responded to our requests promptly throughout the flight. We as a family were not disappointed by Emirates.

It was great, a little more leg room would have been better particularly since we were in premium economy

The boarding process was smooth and the stewardesses were nice. Some delays with drinks at the end of the flight, but no issues.

Thay crew was so nice.Air hostess il ham was so nice.my mom was little scray with airplan turbulence she help us alot.

Seat 💺 was all the way on last row. Food was okay .

Charged for internet that never really worked. The food selection was just ok.

Boarding, seats, entertainment and service were all great. Food was great except for the fact that there were too many sweet items.

The entire crew went above and beyond. This was our first flight with our 3 month old, and they were accommodating and friendly. The crew is attentive and marks a HIGE difference to the regular runs with Avianca and LATAM.

Business class on this plane was adequate, service, amenities, swag, and crew was amazing!

Pleasant business class flight experience with good onboarding experience. Flight service team was excellent with usual book-the-chef menu available

SQ service is great as always. However, the food quality seems to have gotten a lot worse recently.

Wish the underseat compartment don’t have a restriction, can fit a personal item such as backpack fully like most Boeing

Airline should consider adding a small meal at the last leg of the flight, right now there is 7 hours of no meal break.

Crew and service excellent. 2 hour delay for takeoff. SQ app showed flight on time.

Good service and food. For buying items on flight should be preordered as they don’t keep much stock on board.

Very good flight from Boarding to landing -efficient and comfortable with decent entertainment options

Construction at PDX resulting in very lung walk from the rental car to the gate. SFO, extremely long walk between terminals to get to connecting Singapore airlines flight. My smart watch recorded a total of 3 miles.

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

Everything was great keep up the good work 😁, can't ask for more.

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

I was travelling 3.5 years after. Agree Economy is no business class but the food was mediocre. Ordered a Hindu meal, the salads were bitter . The food was really below quality and had no tast from what I had in the past. Indian Railways probably have a better quality food when compared. However the kids meal was really nice and really appreciate how they were taken care of. The restrooms were dirty .

My flight was with American Airlines 120. The flight was delayed 3 hours and I missed my connection. When I arrived in Doha, the AA staff told me to call an 800 number to rebook a different flight, which was unacceptable. Eventually a Qatar Air staff member helped rebook me on a flight to Manila, that was 12 hours later. They offered me a hotel and meal voucher which I declined, because I didn’t want to leave the airport. Long story short, I spent 12 hours in the Doha airport waiting for my next flight.

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

Reason for travelling Tampa to Orlando is to fly Qatar Airline. we end up with American Airline. This was the miserable experience I ever had in my entire travel history. Flight attendants were rude. They hit my knee with the food cart and I was holding ice pack for 2 hours. I still have the pain after a week. WE boarded the flight twice because of the temperature inside the plan.

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

Second leg of Turkish Airline with Indigo is disaster for following reason. 1) You have to carry your cabin bags through ladder to boeing 777 because it was parked somewhere in parking lot and was not given a gate to board passengers and this seems to be people traveling to and fro from those flights and is not issue with flight itself. 2) I choose non vegetarian food on Turkish portal way ahead of checkin to entire trip, However the Indigo flight gave me random veg food saying they code veg food code from Turkish. 3) Indigo did not served any alcoholic beverages stating some weird reason which is non nonsensical. 4)Indigo have TV screens in front of you but it displays nothing except "Welcome Onboard" with annoying white black ground in dark flight. This is the most stupidest and annoying part because you are held hostage for 7 hours and only thing you could do is stare back at white screen which does not have entertainment package or even flight tracker. Such a shame.

nice and clean plane but the seats and the comfort was not what i expected. i expected more based on all the ads and reviews that i've read. I guess you get what you pay for in economy.

Overall it was good. Food was bad. I ordered gluten free vegetarian meal. But I got gluten free chicken for my long flight from Seattle to Istanbul. I don’t eat any kind of meat. Second meal I got eggplant with meat which I couldn’t eat. I don’t understand why we can’t get gluten free vegetarian meal for a 12 hour flight. I eat the bread and that was it.

Worse worse worse, i would not recommend this airline to anyone. Istanbul airport maybe State of the Art facility but staff is rude, only works if they get tips, and they push you to give tips even though my family had spent $50 in tips. Airline staff doesn't speak english so you really can't understand them. It was a nightmare travelling with Turkish. Never again.

As a big guy the seats are way too small for me. Would prefer more comfortable seats on these long haul flights.

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

Boeing 777 is a bad choice for a such a long flight.

The staff at IST airport could have been more helpful. Too much wasted time and the plane from IST to KHI was just horrible. The plane was not clean and smelled bad!

This is my 2nd time with the Turkish airline. Would definitely recommend. In stability we connected to Indiago would not recommend, very cramped seating. No inflight entertainment..service was inferior.

I wouldn't know what the flight was like. AI canceled my flight reservation!! There's no way to speak to an actual human to fix the issue! NEVER AGAIN! ALWAYS BOOK YOUR FLIGHT DIRECTLY WITH THE AIRLINE NEVER GO THROUGH KAYAK OR JUSTFLY.COM!!

As budget airline everything was good. Except that - boarding process can be more organised. Then if entertainment systems are not operational. Its better to keep them switch off.

Flight cancelled after 4+ hour delay. Indigo created a nightmare scenario and showed the most callus attitude towards the passengers I will refer to them was IndiNoGo!

Very nice and pleasant. Boarding was quick and the crew were responsive

Foreign nationals are not permitted to check in online in advance. We can only check in at the airport, so choice of seat was limited. I was stuck in a very uncomfortable location. I would expect a meal included in a flight of this duration. The food options to buy are very basic. IngiGo are a very good domestic carrier, but if they are serious about operating more international, longer haul flights, they need to improve this service to match every other airline I know.

IndiGo is low cost and therefore no frills, but is always a pleasant experience. No mood lighting and fancy features but clean aircraft, professional crew and absolute value for money.

Very hard seats. No food service, even though price is not competitive.

Very hard seats for long flights. No food even on International flight. Won't fly Indigo again if I can help it.

Terrible experience at IST airport due to mismanagement by ground and wheelchair staff.

Some seats don’t recline. No USB port or power outlet, no inflight WIFI - not even for SMS/Messaging apps. Ontime performance was very good. They should have at least one crew member who speaks the local language, for flights like these.

Although we took the XL seats with more width, we found that you do not have a seat in front to stow your personal item, nor can you stretch your legs. This is not the best option for a comfortable seat. Boarding was timely but disorganized without any row based entry.
