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

I got to Rio de Janeiro on time

cramped seats, minimal water offered by crew on 9.5 hour flight. I also found the extra charge to reserve a seat on this flight a serious affront to economic sensibility

Accommodating flight crew. Good food. Nice landing and take off.

I am a permanent resident of USA and have a Green Card and the portuguese boarding crew gave me a hard time about my paper work. I was very disappointed by the way they treated me.

Baggage charges that were not shown anywhere on the website. A nasty surprise when we checked luggage. Lost wallet on plane and customer service was unhelpful.

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,
please send us an and someone from our team will get back to you promptly.
