See / hear the middle-aged guy around seat 22 aisle coughing his lungs out throughout the 10 hour flight without once covering his mouth ? WTF is going on w an airline that would let a passenger behave like this ? Didn’t see the attendants offering a cough drop, or asking if he would please behave like a civilized human being. Looking for others corroboration. Spread the word like this guy this w his germs

I'm 6 ft 2. Legspace was adequate, and no silly boxes under the seats like other airlines that obstruct your feet. Great entertainment systems - modern, good selection. Food and staff excellent.

Their online checkin systems could operate a bit more smoothly. At one point, I had to go in in person, because the online checkin site had an already past flight from their codeshare partner SAS showing up as the next flight, and I couldn't perform online checkin as a result.

Surprisingly TAP told me that they could pay the hotel in Newark, but not in Lisbon.. Go figure! Called TAP Customer Service 4 times, 2 from Lisbon 2 from Newark... all cases more than 1 hour wait...

I bought 2 tikets from Chicago to oscow and back for me and for my son. I live in USA, son lived in Russia but he received immigration visa and I had plan fly to USA with him. From Chicago I used my ticket and say SWISS staff what my son will have trip only from Moscow. I paid for 2 tickets around $1700. Today when we should have trip back to USA, SWISS company said what ticket for my son do not exsist. And I spent for new ticket 220000 rubles about $3600. Nobody in SWISS company do not said me what my tocket for son canceled. I am shoked !!!

The food was good. I have Celiac Disease and they accommodated my gluten free necessities with GF bread!! Wow.

The entertainment for an international flight (9 hours) was horrendous. The tiny TVs were actually fuzzy and it is set up so that you cannot actually choose your movie. It is like watching TV where you may tune in to a movie 20 minutes into it playing instead of starting whatever movie you want from the beginning. To make matters worse, there was no plug-in in case you wanted to watch entertainment of your own on phone/iPad.

Not much. Crew was good but that is about it.

Tight spaces packed in like sardines. FAA seriously needs to look at how these airlines pack us into these seats. Can barely sit in the set, no room to stretch legs, tray table hits my stomach, and I don't even have a big belly. When the guy in front reclines, cannot even get out of my seat. Chaotic boarding process without any order or instructions or announcements, poor food and entertainment.

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,
