Punctuality, calm flight. I have been already too generous with my ratings, above!

To buy a ticket on their site is a mess! Never intuitive, a terrible maze! TAP´s president should be required to buy one ticket each morning... May be the site would improve. Got a ticket with seats “free of charge” on the printed e-ticket, but had to pay for them at checkin. It seems to be a scam... There would be more, but i lost my patience with TAP.

I had only 70 minutes transfer time and had to spend almost all of that time standing in line to go through security after just arriving from another flight!! I ran to the gate and was the last person through before it closed. I asked about my two bags and was told they were accounted for. Hardly believing it but glad to at least have made it I boarded. When I arrived in Zurich, sure enough my bags arrived too! Was very pleasantly surprised!

Though no fault of Turkish Airlines, having to go through security after just getting off one flight was stressful even if it might have been necessary. Almost missed my flight. The security area is not properly designed for accomodating many people at one time and the officials (actually two cleaning personnel) who did not speak anything but Turkish were manning the entrance. Even when I showed them my boarding pass they just rudely shooed me away!

In Business Class, the seats did not recline all the way to become flat. Other airlines (including Qatar and Etihad) have seats which become flatbeds even in 3 hour long flights. Very disappointed that Turkish does not have that options from IST to ISB. The boarding experience from IAD-IST was excellent...but it was the opposite from IST-ISB.

I contacted Turkish Airlines 4x times before my flight to learn how to deal with excess medical baggage, mobility assistance, and meal assistance. The Customer Call Center claimed to have made all of my necessary reservation updates for all of my special meal, medical, and mobility assistance needs. They did not! When I arrived at Check-In, there were no notes about any of my requests, nor services prepared to facilitate them. I spent over 30-45 minutes escalating the situation to the Shift Manager who had to contact the central call center and her own manager, just to find out what to do about medical baggage, what's permitted, etc. I was embarrassed for their employees, who not only didn't know their own company policy on the matter, nor were they aware of the industry standard. After much arguing, yelling and threats, the Check-In desk agents finally allowed my excess medical baggage and equipment without extra charge. I still received no mobility assistance to begin my travel after Check-In to my departure gate, nor were they prepared to offer this to me in Istanbul. Again, after a long wait, much yelling, screaming, and arguing, I was finally provided mobility assistance just in time for my flight. I almost missed my flight due to Turkish Airlines not putting my request in the system, nor caring enough about the traveler to do so at Check-In. When I arrived in Belgrade, 3x pieces of my luggage were destroyed and unusable again, medical equipment was damaged, and I filed a claim with Turkish Airlines. They tried every way possible not to pay, but finally offered a meager claim, nothing close to what it cost for the damage caused or to repair or replacement the destroyed luggage or medical equipment. Turkish Airlines is the Grey Hound of travel, sure they might be large, offer many itineraries and frequent travel, but their quality, customer service and professionalism leave them amongst the bottom feeders, still 3rd world in mentality, form and function. No honor, no integrity, no class. No reason to ever fly with Turkish again, and I'm happy to tell everyone I know not to fly with them!

Had to check 2 of our luggages, and it cost $95 per piece. Never flown an airline where I had to pay more than $50 per piece. Also carryon has to be less than 8 kg. Our small luggage that we had to check never had any problems with any other airlines about being a carryon but since it was over 8 kg, it had to be checked. Took a 7.5 hour flight and the entertainment screen was not working for anyone, as the system was broken. Will not be flying with airline ever again.

TAP Airlines did not fly this route for day and probably hired NEOS Airlines to fly as charter or contract this route only? NEOS Airlines is an Italian airline probably comparable to Southwest Airlines in the USA. It's a cattle car airline with no frills. Crew was very professional, food was actually good. A sandwich that was of course Italian ingredients. Seats were comfortable for the 3 hour flight.

Checking in and paying a $49 excesses baggage fee for I was better off paying a full fare. Discount fare, what a joke!Than finding out that TAP put me on standby status?? But I eventually got a seat. It was no relief thinking I would be left behind and my plans elude be delayed.TAP airlines had only worked the front desk check in, gate check in and don't know about the ramp service. So I can't give a full positive review of TAP Airlines

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,
