Flight on time, friendly crew.

Not so good meals. For a 9 long-haul flight only one meal provided, other was a cheap candy bar. Other carriers do offer breakfast. Traveled with child and did not allow priority boarding at LHR. Limited leg room, I assume this already a trend well known by travelers.

The food was great. The seats were soft and there was enough legroom.

We were stuck on an aisle where the seats don't adjust on one of the flights, but it was a relatively short flight. The boarding process was a little disorganized, but we were able to get on the plane quickly. The worst part was the home airport. I don't know how much control Turkish airlines has over that airport, but the bathrooms we're absolutely disgusting.

Food was ok

The customer service I received was horrible horrible horrible especially from the check in counter the were very rude . After booking my flight on kayak I called TAP customer service just to make sure that everything was fine .I asked them about luggage they said I had 2 free and a carry on when I got to the airport said I had to pay for the 2 i said no told them that i called TAP they didn't wanna hear it i asked for the manager she I am the manager and you bought a discounted ticket and there's no luggage with this ticket only acarry on in a mean way if you want the you have to pay $90 for each I tried to call TAP can't get through them when they finally got through them the guy confirmed that I ve called it on the records but it said now it's too late to do anything I am already at the airport that I have to pay and contact them later. I wasted good hour and a half on this and I had to pay $180. After all that at the boarding gate they announced that they will call by zone .they called especial need called frequent flyers zone A never called zone B all they said last minute was this is the final call for flight #.... and I was right in front of them and guess who were the people making the announcement yep the same people at the check in counter

I have been flying for a while but it is so difficult to find out what fare class you have. the website is not helpful with bag check in information. $90 is way too much to check in a bag especially for an international flight the line at Lisbon for passports is way too long

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,
