The food and the staff are excellent. 90% of the time I can get an exit row seat as I am 6 foot 2. I fly Turkish airlines frequently. This time the plane was full, so I understand that it was not possible.

A passenger and his wife were not seated together, so the passenger wanted to stand in the isle and talk to his wife over the top of me for significant portions of the fight. In a full flight keeping passengers out of the isle os key. I know this was a difficult flight for the crew.

I travel for pleasure a lot and this was my first time flying TAP Portugal. I flew from LIS to MAD and the crew were overall more friendly and smiling than on US domestic flights. The plane was clean and bright. I did not notice if the seats recline. I will be using them for short flights throughout Europe when I return for visit.

Flight was so short they rushed us eating the cookie and only water was served that I could tell. Also, TAP has their own boarding check-in wing of Lisbon airport. It was not clearly marked and Eropean arrows pointing up could mean to continue forward, as well as go to upper floors.

Food was good, many options with entertainment

The person making announcements mumbled and spoke too softly for someone who's announcing things on a flight. We couldn't understand half of everything being said. Also both flights departed late even though TAP reported them as "on time." We sat at the gate for almost an hour before departing with announcements at that time solely in a Portuguese - on a flight going to New York.

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.
