Easy process you definitely need 3 hours to get on board from Fuminchino airport

Very quick flight, efficient boarding, and clear and thorough instructions and attention from staff.

Amazing, not too crowded, great temp and the meal was good

The crew was good. The flight was not overly crowded so we had some additional space.

First time flying airline. Great experience. Clean plane, comfortable seating, great service.

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.

Business class seats were harder than expected, and lie flat we're not very comfortable. Less expensive than other business class flights, and much better than flying economy. The crew was excellent, as was the food.

Boarding was slow and getting off the plane took a long time. The crew did not have enough water for the trip.

Boarding was a bit chaotic, planes were on the oldish side. Otherwise, very nice flight. Would fly them again.

food was terrible on the plane, bring your own food, its not worth eating.

Turkey slices for breakfast. What happened to eggs, bacon, and sausage? The TV shows could’ve been more comprehensive as well as the movies.

The in flight meal was absolutely delicious. One thing I noted was that the meals weren’t just prepackaged tv dinner style options but were actual prepared meals you could tell were cooked that day in a kitchen and individually packaged for the flight.

Special AVML was terrible Movie choices were quite limited Otherwise excellent

On time. Good meal. Overhead cabin lights inop in entire cabin. Seat recliner did not work.

The flight took off two hours late. What was good was that I was getting an information on this earlier in the day. The lounge agent sent the passengers to the gate way too early. That was annoying. The food aboard was disgusting. The service aboard was okay. The seats were good. Overall, it's a very mediocre experience. Well, it's not a five-star airline and not one that aspires to be one. Comparing TAP Portugal to Iberia or Lufthansa, I'd rather see it as a three-star airline, even though it's website works much better than what Lufthansa has been trying to pull off for the past decade.

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

All went smoothly. Got assisted travel which was easily arranged and delivered.

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

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
