It was great like always had all my 3 luggage and I got to my destination safely

Everything was better but france airlines more better than them

Good leg room for people of all sizes. Pleasent crew.

WE didint profit of food , but for the other think all was good

Spacious and clean aircraft. Good food. Economy will always be squeezed but thankfully I had an aisle seat for stretching exercises. Good selection of movies, particularly Spike Lee joint.

Unfriendly, 8 hours delayed, no lounge access even flying business. Don’t fly Brussels

Flight from London was delayed so missed the connecting flight. Taking 2 days to get to destination which should have only taken a few hours.

Suitcase didn’t arrive to Stockholm. Chairs y comfy and not even water is offered

I never board the flight. My visa was delayed and when I tried calling Kayak, no one answer and I still have not heard from anyone.

Boarding time was a bit slow causing the flight to not leave right at 5 pm,but other than that it was fine.

Excellence’s Class booked and we had to wait 15 Hours when we could downgrade to an earlier flight. The logic makes No sense?

Flight was ready to depart on time. We had a 20-minute ATC hold. We still landed on time. The landing seemed fast and rough.

Flight was delayed more than 1.5 hours. Essentially no communication with passengers regarding how long the delay would last or any updates as to the delay.

Clearer signage at Lisbon Airport and more communication about delays

Flight smooth and on-time. Food a joke, crew humorless but efficient. Really a budget airline masquerading as a flagship, but it gets you there.

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.

Overall ok experience as couple feedback: for improvement: 1. The vegetarian food was less and ran out, so many of us didn’t get it. Not all the crew member were polite and could be more hospitable.

No onboard entertainment or food, but that was okay because it was a short flight. Pretty much everyone just slept on the plane. The plane was comfortable enough.

The cabin crew was very courteous, professional, and courteous. Great service!

Didn't get to go because connection flight was cancelled

The airline gets you from one place to another in a reasonable time. Not much more you can expect.

Easy short trip from Faro to Cardiff. Exceptional staff. Early landing and straight through airport in 15 minutes from touch down.

Guide passenger if fhey board from front or back door cause it was a total mess

Nothing unexpected considering it is a Ryanair flight. It does the job. Nothing above, at all.

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.

Flight was over an hour late. Boarding was really messy with long queues at the plane.

Their customer service needs an overhaul. I wish we could access them and the could be more helpful. Also, the website has been crashing and I had numerous technical errors. My flight was cancelled and we spent so much time trying to get help because the tech was failing.

It is what you pay for. Always delayed. Very small planes. Hard to fly with kids.
