KAYAK’s top tips for finding a cheap flight from Seattle to Kolkata

  • Also known as Kolkata Airport or Kolkata Netaji S. Chandra, Netaji Subhas Chandra Bose International (CCU) is the airport that serves the Capital of West Bengal state, India, Kolkata. If you’re traveling to India with a companion animal, consider using Air India, Jet Airways, and SpiceJet because they allow pets on board. At Seattle–Tacoma International Airport or Sea-Tac, pets must remain leashed except when visiting Pet Relief Areas on the Subway level of Concourse D, Mezzanine Level of Concourse S, the Mezzanine Level of Central Terminal, etc.
  • As the 10th-busiest airport in the U.S. that serves more than 36 million passengers per year, Seattle–Tacoma International Airport (SEA) can get very busy between 5 am to 7 am, 9 am to 11 am, and 4 pm to 6 pm. TSA recommends that travelers arrive 3h before their departure flight, so there’s ample time to navigate around the terminal, check-in, go through security, and find your gate.
  • If you arrive at Sea-Tac with time to spare before your flight to Kolkata, you can purchase a day pass to access The Club SEA in Concourse A and the Alaska Lounges in Concourses C, D and the North Satellite Terminal. Lounge facilities at Kolkata Airport are located in the Security Hold Areas of the Domestic and International Terminal.
  • Passengers that need to keep their kids entertained can head to Sea-Tac’s children’s play area near gate A, next door to Qdoba or use one of the seven lactation pods situated throughout the four Concourses. Located at Departure Level 3 and arrival Level 1 at Kolkata Airport are child care rooms available for traveling moms that need privacy to breastfeed, pump or change diapers.
  • While post-security wheelchair services are provided by your airline, Seattle–Tacoma International Airport, in conjunction with Prospect Airport Services, provides wheelchairs, including complimentary Meet and Assist services to passengers with disability. Communicating your wheelchair needs while booking your Kolkata tickets through KAYAK is advisable.

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

Ove the A380 planes. Comfortable seats. Served great Indian food and Masala Chai!

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. The food was great except for the fact that there were too many sweet items.

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

Best airline I think. No problems with anything. Crew were great, no problems with the airline food and entertainment and a smooth flight.

I was in a middle seat where I felt a bit too cramped otherwise the trip was good

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.

We were not given option for meals since they ran out of the other option but good thing the remaining options tasted great.

Both the staff at check-in counter and on board were pleasant and helpful. My chicken and mashed potato was good, sauce was tasty, but the zucchini, carrot n other accompanying vegetables were over-cooked a little. (I understand the meal has to be prepared earlier). Yet I would fly on Singapore Airlines again and recommend it to family and friends.

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.

So happy I flew with Singapore Airlines. The customer service is top notch. I am terrified of flying and the staff made me feel so at ease. Will only fly Singapore internationally moving forward.

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

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 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.

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!!

Paying extra for premium seats was wasted. Turkish Airlines takes 2 seats for bassinet. The lady next to me had a baby with bassinet Bassinet was in front of my seat

Rude staff. I would avoid using the word racist but definitely partially or discriminatory. My 72 yrs old mother who is also disabled was traveling on this flight. She was the second passenger boarded to the plane. The First elderly couple ahead of my mother were allowed to use the airplane bathroom but my mother was denied entry stating it was for safety reasons. My mother objected the the couple in front of her were allowed but hostess still stated that due to the flight safety reasons she can’t use it. Even my mother explained that he is using blood pressure medication that’s why she have to use the restroom frequently but the crew continued arguing her. At one point the Mae attendent even suggested that if that’s the case my mother can urinate in her seat. The level of disrespect against an elderly lady is beyond my comprehension. This matter will be taken to the social media to shame the employees involved.

my experience was great with Turkish airlines . the problem i encountered was with kayak booking. When I booked . it showed that im allowed a bag . and when I got to the airport, i had to pay $165 for one bag.

Not up to Business Class standards. Two of the three toilets were out of order. The hostesses were aware and didn’t show any responsible act to do something. Food quality was not what we expect from Turkish hospitality. Overall we were not impressed and disappointed.

During mid flight, try to get a flight attendant to help I couldn’t find one Otherwise, everything was perfect
