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.

we bought trip insurance from you and could not use it. 'underrated' only return 50 % of trip cost. my doctor told me i have stage 4 cancer and that I might not live till the end of the month..

Flight got canceled without any prior information and it caused lot of trouble

Worst ever. No assistance and communication from Emirates crew. No visibility of when the flight is flying. Couldn’t understand if we can go to lounge to take rest. Emirates system at a certain point said flight is not operating and suggested to take the next flight and in few minutes it suddenly opened the gate for boarding. unsupportive and rude crew. Worst experience ever. Flight was delayed by 5 hours so need the compensation for that.

Staff were friendly, and provided great service. The food was plentiful and delicious. Food could have been hotter.

I was traveling business purposes and I only had one carry on and a personal computer back pack . My carry on was 8.5 kg little more than allowable. At jfk airport check in they did not let me carry it . I was little disappointed.

More leg room and comfortable seats at least for long flights

The entertainment selections are amazing. But the live TV is sometimes spotty. If you’re going to have it, then have it. If you can’t make it consistent, then, perhaps it’s better not to have it. The crew are always cordial when approached, but they seem to do the minimum and sit around, talking to each other in the back of the plane during the flight. I realize that delays are not always predictable, but I missed my flight in Dubai because we left 90 minutes late from Washington. I will say that Emirates took very good care of me in Dubai. But I would rather not be delayed.

Probably the best flight I’ve ever been on. Emirates first class is leagues beyond British airways and Lufthansa’s.

Great flight. Comfortable seats, courteous service, and excellent selection for entertainment.

Emirates flights always nice. Service rendered by the staff is superb.I am always comfortable in Emirates flights.

I arrived 59 minutes before the flight in Tampa due to Massive traffic jam and the flight was closed and I was told that I’d simply have to “book a new ticket on line myself and the gate agents couldn’t help me”. Even though the flight was delayed over 30 minutes, (leaving one hour and 29 minutes before departure, they refused to assist in any way explaining that it’s automatic and there can be no exceptions. Horrible experience due to poor management at gate. I fly this option 2-3 times a year and have a good experience with the cabin crew etc. But, Tampa agents are not trained or allowed customer service. I once was a gate agent for USAir, I know times have changed, but forcing me to purchase a new ticket and complete indifference and inconvenience. No thanks

Crew members were good. Seats were packed and too tight .

Carry on luggage size for economy passengers significantly smaller than other airlines, so nearly all ecomy passengers had their bags taken and checked.

Had a short layover in Zurich, luggage marked expedite and short layover but still didn’t get luggage when arrived in Split until 3 days later even though husband got his.

On time flight, I requested wheelchair in Zurich , when I arrived they were no where to be found, I had one hour between flights I had to walk with great difficulty.

We had issues with upgrading our seats. The flight itself was fine.

Horrible experience. They "GAME" with seats they decided to play where you can`t select or get seat during check-in without paying and then forcing you to stay long line at the Customer Service at the gate to get a boarding ticket with seat assigned is pathetic. Will never fly with United again!

SO disappointing. I spent so much money on this ticket, for them to cancel and not be able to rebook me in time. They were very unhelpful, and condescending throughout the whole Swiss airport. Will not be flying again.

So terrible. They would not rebook me for a flight until 2 days. I had to spend so much money to get my own flight. They were rude and not helpful.

Overall a good experience, the flight was on time, the crew very attentive and friendly. However the seats are too cramped, there is no space, and as soon as the person in front reclines the seat, it's literally in your face.

Besides the flight cancellation, everything else was prefect. Kudos to Malaysian Airlines.

Operated by American Airlines. Very chaotic and the crew was bit rough responding any enquiries. Restricted leg space.. Qatar would have been better

No towels or tissue and chocolate and mint provided before arrival

Qatar airways from Doha to guangzhau was excellent big bird Boeing 777 more room and smoothly flight, I Love it

It was good no problems made it on time for the next flight overseas!

They made us deliberate waste time by holding our passports and boarding passes making us miss the flight

The made us waiting and held our passports and boarding pass making us miss our flights

Not impressed. Only allowed one carry on on such a long flight.

The flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.

Bad experience with the delay n long wait time for connecting flight after missing the connection flight from Doha.

Lovely crew - comfortable journey despite it being an older plane.

Overall mediocre experience. Check in was good. They're were discriminatory. They were not attentive, food choices were not vegetarian friendly. The food served was frozen.

Good range of movies but lacking decent tv shows. Wifi was really expensive on this flight, considering flights under 7 hours have a $9.99 USD charge for streaming, to jump up to $24.99 for a 7 hour 40 flight seemed a little bit of a rip off. Staff are inattentive, and really need to improve on the customer experience. The new airport is fantastic, as is the new lounge, a huge upgrade from the old airport and lounge!

It has been a couple of years since I flew with Etihad last, after having a unpleasant experience with them coming out of the pandemic. I can say that the experience has uplifted, but I can’t really rate the service. At Barcelona airport the service was great, with their dedicated Etihad staff very helpful. The onboard experience wasn’t great, not very personalised and it really makes sense why Etihad doesn’t feature in the top 10 2023 Skytrax awards. The crew just seemed to be inattentive and almost absent from the cabin. I felt that I had to keep getting their attention. Even after I’d finished my meal, an hour went by before I had to call them to clear the tray/plate etc.

The staff was kind and polite, but it was very very hot and no ways to have some fresh air.it would be also be nice to have more time to sleep, since it was a night flight

One thing is very important is you people not giving seat arrangement together to couple, senior citizen. You have to take care of senior citizen. Do not look about money. Money is not important everywhere. Make relationship strong is very very important. I like Etiyad air line out of all air line. Food was hot and delicious. Air hostess gave very good service, nice attitude, very good behaviour. I gave 10 out of 10 marks. Thanks Jivraj

Entertainment did not work from flight from Abu Dhabi to Kolkata. Emirates has a much better flight in that sector.

Ripped off and broken seats in Business class. Seats stink and need to request the staff for additional bedsheets. Crew if very friendly though

Food was very good. Again tray could use a non-skid mat. I had a regular seat - comfortable - able to sleep undisturbed. Boarding was uneventful.

Boarding was quick and efficient. Ground staff were pleasant and courteous. Food was tasty, portions were good for me. Food containers kept slipping on the tray. Tray would look better with an anti-skid tray mat. I had the bulkhead seat which was very uncomfortable for couple of reasons. Aircraft is designed with no throughput to move across aisle to aisle. Passengers kept jumping over my legs to get from one side to the other to use the toilet. Secondly I had a mother and 9 month baby next to me. Mom had to hold baby for 12 hours in her lap as he did not fit into the bassinet. Half the baby was on my lap during the flight. Aircraft temperature was very cold - light attendant said it was the central cooling and nothing could be done about it. Movie selection was very poor old and outdated.

There was a screaming child behind our seats. This prevented us from getting any sleep during the night.

There was a screaming child just behind our seats. This prevented us from getting any sleep during the night!!

Staff disappeared after dinner service until breakfast, no help with beds, no help running to our gate to catch connection cause flight was late, our luggage didn’t make it, took over 24 hours to get luggage to hotel, no compensation!!

Everything was good except food. I believe there is room for improvement

Houston to Porto flight delayed landing made us miss our connection. Tried to get on standby for the next flight and even though the lady knew we wouldn’t be able to get on it and she sent us down there. We sat there three hours and then we’re told there’s no way you’re getting on this flight. So we had to go to customer service and ended up having to spend the night in Frankfurt and missed a whole day of our vacation in Porto

my flight was at 3:45 after that they delayed to 4:40 I have transit from Chicago to Frankfurt and Frankfurt to vina airport from vina to Erbil buy the Time I come to Frankfort my other flight left me I have to stay at airport all day with my 5 kids ask for help no one help me I spent at airport almost $450 just for food was horrible flight ever I call and ask for hotel from united customer service they been telling me we can’t provide any hotel I need some refund or fixed my flight when I return to America need some one respond my email

My experience would have been greatly improved by arriving on time to connect to my Porto flight. The staff that dealt with the aftermath of the late arrival evidently booked my group into a hotel in Frankfurt. This reduced my time in Porto Portugal a day and half. I do want to commend Jorge Klein for his hard work. He spent a great deal.of time trying to rebook the flight and he eventually did rebook for the next day and did provide accommodations for me overnight. This was a big issue for me and the group I traveled. The rest of the trip was good.

Not your fault…..didn’t get my drink until just before landing….bumpy flight.

Lufthansa flights were great. United flight from houston to Frankfurt had very small seats with almost no space

Second time I took this flight, and they lost my luggage both times. Waiting for my suitcase now, last time it took two days to get it back.
