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 3.0

Cons: Seats were atrociously uncomfortable for a 6'1" man. Less than zero leg room due to ridiculously tight row spacing and non-reclining seatbacks. Had to attempt to cram in sideways - resulting in serious pain by the time the flight finally landed. Intercom system, especially from the captain, was painfully grating and loud. Boarding was extremely slow, in part because gate personnel made no effort whatsoever to police and enforce the four-group boarding process (premium - no carry-on - group A - group B). People boarded whenever they felt like it, many carrying on huge backpacks and multiple other pieces. Will definitely avoid TAP in future.

Good 7.3

Pros: TAP always has great team members and crew. They are polite, professional and helpful. The flight itself is comfortable and relaxing; very enjoyable.

Cons: TAP does not check your bags all the way through if you are having a layover. This makes NO SENSE and requires that you retrieve your luggage from baggage claim, and then check in once more and then another trip through security once again! This never happens in the US - one of the few things we get right. Also, I have never had to board a plan from the tarmac since 1970 in the US - why do we have to always wait for and take buses from our check in gate out to the flight line? And how is this ever considered, "Premium Boarding?" It's like a cattle car. Fix these things and I will sing the praises of TAP forever.

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

Cons: the flight was fine, but not being able to checkin online is VERY inconvenient, and I spent TOO much time trying ot reach Aer Lingus, Justfly, BritishAirways to get checked in, with no success. The reference number needed to check in for the operating airline should be provided to the passenger.

Pros: the seat configuration is 2/4/2 so if you get a seat by the window, you have your significant other or friend next to you and no one else which is nice. Food was decent.

Cons: Entertainment didn't have any interesting movies or TV shows. Bottom of the barrel. No coffee or tea was offered before landing and it was advertised.

Good 7.6

Pros: The meal and drink service was quite good. The stewards/stewardesses were very attentive and kind.

Cons: There is not enough leg room. There is even less room if the person in front of one's seat has the seat reclined. The seats barely recline at all, so sleep is impossible. Sleep would be possible if there were enough room to rest one's head on the tray in front of the seat. This is impossible if the person in front of one's seat has reclined his or her seat. Thus, sleep is totally impossible on this aircraft. The sinks in the bathrooms also need to be deeper and need to drain more quickly.

Pros: Amazing crew, great customer service and high level quality plane, despite only 1 hr travel, they served small breakfast and chocolate

Cons: Despite the fact I bought my tickets with 1 hand luggage + 1 personal item, they forced me to dispatch my hand luggage stating flight was full, I refused and they said they could not allow me to board. Felt my rights violated, I HATE to dispatch luggage... and in the end there was space left on the airplane luggage storage areas. Not nice

Excellent 9.0

Pros: The food, the staff and the free movie on the airplane.

Cons: My American partner's passport expires 2 months after our return to the US. Unfortunately, the French issued a year ago the following rule: to enter France, the foreign passport must not expire at least 3 months after the return date. British Airways let us fly to London, explaining this to us, how it would be on us if there were problems further down, and that we would have to get our luggage in London. We chose to fly thinking it would be OK, we had listened to an online person who had had the same problem and the French later told him they would have let him in, also I am myself a dual citizen of France and the US, plus I am autistic, an invisible disability (in my case) that makes it impossible for me to travel alone. I usually do not even say it since not much is understood -by those who do not have it- on how to accommodate it However in London BA did not allow my partner to go on. Due to the fact yesterday was Easter Monday, the American consulate in London was closed. We have spent the night in a nearby motel and now, the next day, I am waiting alone back at the airport with our 2 large suitcases while my partner is at the American consulate. We are poor, do not have phone, currency or charger for England, and I do not do well with stress, so it is difficult. Now we cannot easily reach one another. We hope to be able to fly on a standby basis (that's what BA told us we could hopefully do) later today. Sorry for this long letter, I hope it does not bore whoever reads it (if it is even read :).

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
