No one would update that the flight was delayed. They would not even communicate as to why delayed and would not put us in a different flight. Absolutely no customer service. Disappointed and would not fly jet airways again . I missed my conference lecture today as I was late.

No communication, nor will they tell you why it's late . Nor will they move you to another flight even wen requested

The crew was friendly and professional, the food was good and offered frequently due to the long flight time (10.5 hours). The plane was comfortable even though nearly full. Overall, it was a good experience and I would definitely fly with Virgin Atlantic again.

All flights have been on time. Seats and entertainment system are acceptable

Apart from the unorganized immigration and check-in process the service is very average. On both transatlantic flights the toilets did not work properly. Furthermore the business practice to charge you for any luggage $ 90 at airport without prior notice during the booking process is quite unpleasant and uncommon for transatlantic flights. Would be good that airline as well as internet travel agent would advice about this additional costs in a more transparent way before you purchase the ticket

Worst flight experience I've ever had and I'm 70+ years old. In Dublin we were diverted from JFK to Hartford due to "mechanical problems" and told we'd be met at the gate and provided ground transportation to JFK. Approximately 30 others going to either JFK or Boston were told the same thing and joined us on a half empty flight to Hartford. When we landed there was no representative at the gate, no ground transportation provided, and no effort to help us. A little investigation on cell phones revealed both the Boston and JFK flights left on time (and I'm guessing full). Needless to say the customers were quite upset. Some even raised their voices which caused the kid representatives of Aer Lingus to call the state troopers (really). When the troopers did nothing the Aer Lingus reps locked themselves in their office rather than deal with their customers. After 2 hours of waiting for the promised ground transportation we gave up, rented a car, and drove ourselves to our destination at our own expense. We were never provided even a free drink. Horrible. Lies upon lies upon lies. I'll never consider flying with them again

We were told over the phone that we could bring our kayaks with us to Africa but the airport staff denied not only our kayaks, but also our paddles which were in a standard ski bag. Their excuse was that both the kayaks and paddle bags were 2 inches too long. .. TWO INCHES!!!!!! We had record of the person we talked to and the time and date, but none of that seemed to matter. It caused A HUGE INCONVENIENCE for us since we are in Zambia for 6 weeks without our gear to paddle one of the most challenging rivers in the world... the Zambezi. Now we are constantly trying to acquire the proper equipment with very little success. We run a nonprofit called the Montana Kayak Academy which provides free whitewater instruction to youth between 8 &18 yrs old and we will be sure to tell everyone we know to NOT TRAVEL WITH EITHER VIRGIN ATLANTIC OR BRITISH AIRWAYS.... EVER!!! VERY DISAPPOINTED! !!!!!!!!!!!!!!!!!

We had lots of seat space because the flight wasn't full and we could spread out a bit. If the plane hadn't been full, the seats and leg room space were insufficient. The food was good. The on board entertainment was enjoyable, making the time go by quicker.

We weren't able to select our seats, they were selected for us. We also couldn't print out our Boarding Passes until we arrived at the airport giving us an uneasy feeling about the seats we would be assigned. Ultimately, our seat assignments were fine, but no need for the drama.

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.

If you have more questions or if you have a bad price to report to us,
