Excellent 8.0

Pros: The seats are comfortable.nice leg room.

Cons: Boarding on every airplane company seems off. Sitting in seat 6D and I’m in the second to last boarding group. That cheese on the burger pricing for getting on before others is getting old. Be better.

Poor 0.0

Pros: NOTHING because they cancelled the flight and wanted to charge me 100% more for an alternate flight during the corona virus crisis. They were price gouging which is unforgivable

Cons: Their leadership has much to do in terms of their actions in a pandemic situation. Shame on them!!!

Mediocre 2.0

Pros: The price was good. The staff really tried to help, but the restrictions from TAP headquarters made them effectively powerless

Cons: The flight was canceled last minute. TAPs phone support were not allowed to reschedule anyone on alternate carriers, but told me that the check in agents had that power. Meanwhile, the check in agents in Boston had been banned by TAP headquarters to rebook anyone on other carriers, and were unaware that the phone support were giving the passengers conflicting information. In the end I was automatically rebooked for a flight 72 hours later (not realistic for me...). I gave up and headed home from the airport after 2 hours. People who needed help with hotel bookings (not me luckily) most likely had to wait in line a lot longer than that

Pros: There is nothing to like about the flight

Cons: There was no entertainment , no food for a 4 hour flight. The flight is more expensive than other airlines. I will not recommend or flight with them again. The flight was full and I think the route is profitable to them. I guess if you can exploit people, why not do it.

Pros: The crew were very nice overall but one flight attendant in particular was incredible. I didn’t get a name but he was friendly, welcoming, and kind.

You would think with coronavirus it would be sealed like on American Airlines. No sandwiches or anything except some nuts and a small diet coke. I had to ask for a second one. It appears they only care about the people from London. Deplaning was from the middle door and it was a free for all. They have no idea about service well at least not in this leg.

Prices are per person, are for e–tickets and include all taxes & fees in EUR.

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 hires 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.
