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.

On time take off and early arrival, what else can one want

My last few flights with Emirates have always been delayed at least a half an hour. When my layover is only an hour and a half to two hours, 30 minutes makes a big difference. I’m going to check out other airlines.

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.

I don't think I will fly Swiss again. I had issues with carry on luggage, connections were really tight, food was average, I paid extra for an aisle seat, then it was changed at check-in, the app/website don't allow you to add extra baggage if needed, and it was the first long-haul flight that didn't provide alcohol (glass of wine with dinner).

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.

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.

Long way to improve. Toilets not working. Bad handling when flight was canceled

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.

United delayed the flight to assist customers to make the connection. The Ohara customs area was overwhelm which created an issue for customers trying to make the Little Rock connection. The delayed allow several customers to make the final flight into Little Rock.

Missed our flight to London and we were put on coach seats to Munich.

Terrible. Missed our flight to Newark as well as our flight to London. Complete disaster

They canceled our flight last minute and we had to get another flight with twice the cost

Dinner was excellent - beef stew, the eggs for breakfast were only ok. It was soooo nice that there were so many options for movies and games.

Captain waited 45 minutes for late passengers boarding from Washington DC to Munich which was nice for them but caused our luggage to miss boarding our connection on to Bucharest. We then did not receive our luggage for about 48 hours after landing which was very inconvenient for our travel.

Poor, we had 1 hour to grab our checked luggage, go through customs, recheck bags and run across terminals to make our United flight. Poorly planned connections.

Check in in Albuquerque was awful. The people were great but they were over loaded. The procedures were terrible. We got through fine but it took 90+ minutes.

Will try to not fly with them again. Delays because of weather but got redirected to an airport where I could not make connection.

Staff didn’t care in business class. Closed the door on my mom while she was on the jetbridge and flight attendant told me she would make it from the connecting flight. They lied. My luggage was damaged on arrival. No success in filing damage claim.
