I was advertised a free seat selection for a "Smart" fare through BusinessClass.com. I was never able to select a seat. I thus paid extra for a bill of goods I was never provided. would love to speak with a representative of Kayak

Overall good. We weren't able to find out about food options for the flight and there was nothing I could eat due to allergies. The biggest problem was getting our checked bag at Logan. Waited an hour!

I loved both of my flights to Ireland and back to Boston. The only negative was it took over an hour for the baggage to be delivered.

The boarding time for this flight was ridiculous, longest in all my time flying. There was a problem with the original plane so it was switched at the last minute. Not a good substitution. We were delayed in departing. The bathrooms for economy were not adequate. The crew were pleasant but not present in the economy section, in an ~ 8hr flight only twice did they come through offering water, easy to get very dehydrated. I had to go and ask every hour for more water. The seats were cramped, and I have no idea what they did to the coffee but it was undrinkable. The food, was disgusting, utterly inedible, I am stunned by the lack of care and quality with the inflight service, very disappointing, I had expected better from Aer Lingus.

Excellent cabin crew. They helped a number of passengers with mobility challenges and a mother with a 3 year old and an infant. Better than most other airlines by far. Well done Eduardo!

Good, I slept the entire flight so I cannot add many inflight details

The embarkation at Dublin was a kin to a Ryanair approach, in other words a circuitous and cheep access

Excellent flight and crew. Boarding at Dublin Airport was a very difficult trying to find the right gate.

Delightful flight, ahead of time with a super crew, thanks

I had a great experience. I wasn’t sure what to expect but the crew helped me check my bags and made sure I got in the correct line to board. It was a bit of a walk to my gate so arrive early. I would recommend securing a flight that includes checking in your bag if you remotely think your baggage is over 10kg/22lbs. Be safe and upgrade unless you are carrying a backpack or weekend type baggage.

The food was dry and tasteless. Boarding process was ridiculous. Lounge is Lisbon was of very poor quality. The website is nearly unusable. Customer service was challenging. This was my first transatlantic business class flight with TAP. There will not be another.

Disappointing Compared to other airlines , this one was the most expensive. But not even close, in getting what you paid for.

TAP canceled connection and we had to wait 15 hours for another flight to Milan. There were plenty of. Seats on earlier but because we were Excellence Class the would not let us downgrade which we were willing to. Don’t understand their logic? Plenty of seats but we couldn’t / they wouldn’t make the change.

Food is poor. Drinks in dixie cups, only white/red wine in Premium Prime despite business class food-which even that is a joke. Second “meal” on a 12 hour flight is a bagged sandwich in a cardboard box, which on premium airlines is a snack served BETWEEN meals. The premium economy product has some good parts but is obviously a cheap way of somewhat upgrading economy without actually putting any money into it. Lisbon airport is overcrowded and almost 3rd world as an airport. Crew is efficient but militaristic-crrtianly not “warm”. Entire experience feels like an intercontinental budget airline.

Excellent experience - from boarding through the super smooth flight The food was mediocre and the app could be better but overall great experience

This was one of the worst flights I have ever taken in my entire life. First of all, I traveled Economy, but the seats were TINY and cramped. Not just for me; everyone around me was complaining of the same thing and said they could not get comfortable. Then there was the issue of the heat. For whatever reason the heat on the plane must have been turned to FULL BLAST, because even at 30,000 feet, it was SWEALTERING. Everyone was drench in sweat. Then, they were SO STINGY with the amount of drink they would give you. If you asked for water, it was in a tiny, paper cup (think bathroom cup) and they only filled it 3/4s of the way as if the cost came right out of the pockets of the air stewards. Everything was a money grab, you could tell! You had to pay for the WiFi, which was garbage slow, and the onboard entertainment was limited and stale. If I EVER fly TAP again, it will not be Economy class. What a disaster!

Everything was good with Tap Air Portugal. It was Logan Airport that was a problem. The fuel system was down and delayed my 10:40 boarding. I wasn't able to board my flight until 2:00 am...after that my flights were great.

Seats had no charging ports. Our plane was rerouted to Boston and we were landed on the tarmac with no food or water for 3 hours (illegal). We then waited in the airport for 3 hours while staff had no information regarding where our bags were or when we were going to get them.

Very poor communications during flight. Our flight was diverted with no communication. We waited for hours in the terminal for word on how we would get to Newark No chargers on the plane Won’t be flying them again

An hour late. Plus literally everything was unavaiable for food and beverage service. Will never fly again. Ever.

Smooth journey made good time. The aircraft was littered and did not look very presentable.

On time departure; arrived early into Faro. Air Malta operating flight, crew friendly and efficient.

I didn't know that all connecting flights require online check-in two hours in advance, so I was fined 55 euros. This is a lesson learned.

There isn’t any entertainment. The food and drink was available for a price. I didn’t buy any.

It would be nice to have power to charge phone.

They boarded us but somehow did not manage to record us boarding, so rather than check if we were onboard they removed our bags from the aircraft. I got a call from Ryanair staff in Dublin when I landed in Madiera asking me where I was!!! When I said I was in Madiera I was told what had happened. Our bags were to be sent to Madiera the next day via Manchester, they didn’t arrive. They are now due to arrive two days before we leave. I don’t see myself using Ryanair again unless I am forced to and even then I may just refuse.

I haven't had a ok flight with Ryanair in so long!

Ryanair is the worst airline in Europe and easily one of the worst in the planet

Em relação a Ryanair, ter de ir ao check-in só para carimbar o cartão de embarque não foi muito fácil, são muito demorados, e atrasam a passagem do controlo de passaporte... E cheguei com 2 horas de antecedência

Usual RyanAir flight but disembarking was poor, no rear steps. The Faro Airport required lots of up step and down steps, no elevator Getting through passport control took 50 minutes in the EU line
