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.

All in all the flight was good. Love the fact that for airline food it was piping hot

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

It was a great flight Food was great Crew was spectacular

In general good, but the machine seems to be long in operation and some functions were restricted as e. g. Adjusting of seats.

It seems paying premium economy does not make difference with economy. No priority boarding, not worthy paying extra$$$ for premium economy.

Wonderful service, planes and interior in great condition, very pleasant experience

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

The singapore airline now compared before covid, I like the service before covid. SQ was the best of all airlines but now I am going to look for different airline if I am travelling in asia.

Flying with Singapore airlines is always excelllent - the crew are lovely and the food too is great. It’s my number 1 airline

Perfect experience from boarding through to leaving the flight, comfortable and personalised service from all staff, highly recommended
