I bought a ticket for three persons: my wife, my daughtet and me. I am Nigerian, my daughter American, and my wife's Turkish. However, because of the diplomatic row between Turkey and the U.S., my daughter was refused entry into Turkey. Turkish airlines' policy was to refund the ticket of any American caught in this row. They said they will refund my one month old daughter's ticket. However, my wife and i will not receive a refund. We bought the three tickets together. Our ticket numbers ended in 235...51, 235...52, and 235...53. However, they will not refund our whole money by cancelling the ticket but only that of my daughter. So this is the question: Does Turkish airline want me to leave my one-month old baby in the U.S. and tavel with my wife to Turkey? What kind of parents will we be if we were to abandon our daughter to take a trip to Turkey. Even, the people in Turkish airlines will judge us evil parents, yet that was exactly the only option they gave us. Lose your daughter or lose your ticket money. They will not even just change our iternary or give us another destination we suggested without penalties which are almost 3/4 of our initial ticket price. They just made away with our money. You cannot say, 'We are cancelling tickets for American citizens' but make no exception for parents of infant citizens. This is the height of criminality. So, me and my family couldn't take the flight and lost $1500. We had to buy another ticket by airfloat to get to Georgia. But Turkish airlines refused to even contact us on the refund for my daughter. A truly criminal enterprise.

They had a vague refund policy for Americans, forgetting that American infants can also have none-American parents who are as much victims in this as the American infant. For them to be myopic and keep repeating talking points of their refund policy is unfortunate to say the least.

The food and entertainment was good. The crew was very nice.

seats too small. I am 6 feet tall. The guy in front leaned back and my knees were jammed for 12 hours. I think this is a violation of gineva convention.

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.

The food and flight attendants were very nice and accommodating.

I had a 17 kg big baggage and a 7 kg hand baggage and was forced by the hungarian check-in attendant to pay the equivalent of 112 usd. I nearly missed my flight as nobody understood why I had to pay extra since my baggage was under - weight. Outrageous! Will not use Tap Portugal again and definetly won't recommend. Maria Petrita

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

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.
