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

  • If you’re in a hurry and need to get to Boston Logan Airport (BOS) as quickly as possible, take a taxi instead of using public transport. Not only are they easily accessible from anywhere in Boston, but they also take a very short time from downtown Boston to the Airport Terminal.
  • Boston Logan International Airport is a major hub for Delta Air Lines. Therefore, you should consider booking your flight with them since they will have more flight options compared to other airlines.
  • To get wheelchair services at Netaji Subhash Chandra Bose International Airport (CCU), ensure that you inform your travel agent or airline that you will require the services at least 48h before departure. This gives them enough time to organize with the officials on the ground and make the necessary arrangements.
  • When booking connecting flights, go for the automatic transfer instead of the self-transfer option. This will save you the trouble of having to check yourself and your bags into every individual flight.
  • Consider the offsite parking options if you plan to leave your car at Boston Airport. In most cases, they are usually cheaper than the parking lots inside the airport. On top of that, they also offer a free shuttle to the airport terminal.

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.

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.

Not sure how we end up with American Airlines instead of Qatar Airways. From Philadelphia to Qatar they boarded us then they asked us to unload. After 30 minutes later they board us again. The inside the plane it was burning hot and we were sweating like crazy. Crew members are absolute rude. The way they served the passengers were horrible. One of the crew members hit my knee with food cart and kept going. I was holding an ice pack for almost 2 hours. I am still with the pain.

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