They provided a pillow and blanket which was very nice, and the crew were helpful in finding space for items during take-off and landing. The boarding and exiting were fairly quick.

Everything on board costs extra, including basic drinks and snacks, but that's to be expected on cheaper flights. I assumed that the inflight movies cost money as well, although I didn't watch any because I didn't have headphones.

The crew from the gate/customer service desks to the flight crew were very nice, Norwegian is very lucky.

My flight was delayed by almost 6 hours. For days I received alerts about it being my last chance to upgrade my flights. Many hours before my flight they knew the flights were delayed yet I did not receive one text or e-mail to let me know. I was at the airport for 9 hours. 9. Worst part is that I'm not even the only one.

There was one particularly pretty crew member with a great laugh and she was very friendly

I flew out with the same luggage that I flew in with. They charged me $56 for it. It seemed as if they made a new rule out of the blue and included my personal bag my carry on. It wasn't that they had to be concerned about the FAA weight requirements because the flight was only about 80% full. The in-flight entertainment was limited and there was no audio... so in other words, you could not simply turn on music to go to sleep by. This is a very bare-bones airline. Also, one flight attendant was perhaps the rudest person I've ever come across. "Go talk to someone else - I'm busy." All I asked for was a fork. She was simply opening a bin at the moment.

The flight did eventually take off, unlike a few others leaving around the same time.

We were delayed several hours and were never told why. Mostly there were no Aeroflot staff at the gate to ask. When there was, they said they couldn't help us because our flight was a codeshare with FinnAir. At the last minute they switched gates, sending us all scurrying.

The crew was nice

I flew American four times in 7 days, every flight was delayed. delay times varied from 90 minutes to over three hours. Fog in Chicago was beyond anybody's control, but the other times were not weather related, I recently flew frontier Air and their flights were also late. I jinxed myself by stating I never have this issue with AA. Great job at proving me wrong. I flew a good bit last year and these issues didn't start until after the new year., Thank you for your time.

None of the experience was pleasant

First flight was delayed causing us to miss the 2nd flight and we ended sleeping on a chair at the airport waiting for a morning flight. AMERICAN AIRLINES didn't even have the decency to put us in a hotel for the night due to their delay. Then they added a 2nd lay over which was delayed for hours also. Traveling was to visit my mother who had cancer and I was sick so this made the trip even more distasteful.

The flight from Toronto to Boston is extremely short, about an hour. I don’t feel as though I can rate the food since I didn’t buy any, it just doesn’t give me an option to not rate it. It was a completely full flight. It was as comfortable as can be. It’s a smaller plane so you feel everything but the captains were good flyers.

I’m not sure if this is something I can really complain about but I wish the flight attendants would’ve spoken a bit lower. For a plane where half of the people there had missed their connecting flight and were put on a 6:30 am flight, I don’t think we wanted to hear about their detailed personal lives.

I'm very disappointed because i wasn't allowed to travel back to the US from Brussels (Belgium). i was supposed to connect in Toronto but because I'm a foreign student in the US, I wasn't aware that i needed a Canadian Visa to transit in Toronto. so lost my flight and i hard to spend another thousand euros to catch the next flight that will connect in the US territory. I made all the call possible to resolve my flight issue and no one could help me either Brussels airline personnel or the kayak customer service. until today i didnt have not even a email to let me know what happen.

Generally like Lufthansa service - have been flying the airline for 15 years+ Pilots are always excellent

Every flight (to and from India) seems to have the chicken option run out. Why not order accordingly? Had a bad seating experience. LH.com showed that I had completed the boarding process. But when I went to the counter, my seat was changed without my consent (to a worse seat), and I was told that the online process wasn't complete!! Then the website should say accordingly. It's really annoying when this happens. I think the ground crew in New Delhi duped me. At one point, my call button for my meal was ignored for ~30 minutes on the plane. And then I was told there was no more chicken, and handed a veggie wrap. One wonders whether I could have gotten chicken 30 minutes ago!

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
