Questionary would have N/A available, I did not eat, can't say I'm either sad or happy with that.

budget airline, you get what you pay for but pilots flew great, crew was awesome!

I mostly blame the dreadful Berlin airport, not Norwegian, but we departed in the rain after trekking for a mile to get to the gate, carrying everything including our baby and luggage down a couple flights of stairs and then walking to the plane on the tarmac in the rain and climbing more stairs to enter the hot airplane. The flight itself was fine, but sitting in the cramped chair, soaking wet, baby in lap, also wet, was hard to overcome.

Delays, uncomfortable, and no compensation or free water after being stuck in the plane for more than an hour!

Flight was 1 hour late. The luggages also arrived 45 minutes late.

The flight was delayed by 1.5 hours & the gate was changed, so it was a long walk from the 1st gate to the 2nd gate. The bags took about 1 hour to arrive after landing. Ridiculous wait for bags for which we paid extra $$$$$$$

The upholstery of our seats (7A+7B) were in bad shape: twisted, hard and uncomfortable. We also had a 55 minutes delay. Apart from that everything was OK.

We arrived on time to our destination and the flight was peaceful (and short!.)

30 minutes late as usual. Could not pay for any food or drinks, despite using three cards. Amex, Mastercard and Visa. Uncomfortable seats

I was not well I have got high temperature there for I never made to to airport

Short flight in an Embraier. Business class seats didn't have leg room, but the rest of the upgraded amenities were great -- priority boarding, great in-flight meal, etc. No wifi nor entertainment, but that's fine for a 1.5hr flight.

Bid process for upgrade is very frustrating. I was notified that I had won the bidding, then was told there was no seat available.

The quality of the food was 👍 excellent , I would have like to have in my meal : eggs and a protein bread, or dark bread , mayonnaise and a big cop for the coffee , cuz I am a coffee lover!

Overall a great experience. I didn’t like that they didn’t assign seats until we arrived at airport. All the employees we interacted with at the airport and on the flight were kind and helpful.

It was ok but no WiFi I think I’ll fly Iceland air next time

Basic flight. Great for something under two hours. Seats were a bit dated and uncomfortable

They lost my luggage and there is no update, no luggage and no hope that they will find it. It has been 26 hours since we landed

My daughter always gets sick when we order the gluten free meal option. Internet didn’t work as advertised.

Nothing to answer your questions appropriately. It was just a 2hrs flight from London Heathrow and we were served a cup of tea only. So the questions about food aren't relevant and also, there's no entertainment on these short haul flights. Overall, the flight ✈️ was okay.

The connection time from the flight to Stockholm and the flight out of Stockholm was too short. Due to a knee injury, I almost missed the second flight. From deplaning at E5 to boarding at F69 takes more than 40 minutes.

Had no disruptions or delays. Did not order any food.

I liked almost everything (e.g. ease of booking, price, punctuality, efficiency, friendliness, courtesy). A slam landing in Dublin airport took some of the gloss off it, though. Being able to paste here the text of the review of the same flight that I just wrote for Ryanair would make me feel better about Kayak too.

Take off was great but landing is always with a bump.

Staff were very professional. Much better than the outgoing flight from Dublin. Seat cushions were practically non existent. Making for a very uncomfortable flight.

They were extremely unprofessional and unhelpful at check in. They did not understand laws related to Spanish residents flying with family It was very discriminatory the way we were treated.

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

Flight was fine, crew were good, cabin director spoke far too much; disembarking at Dublin Airport and entry into the terminal building was just dreadful, like entering the back door of a neglected factory building. What an awful impression it must give to first time visitors to Ireland.

all fine - did not have food - there was no entertainment

Delayed delayed delayed and then cancelled very late not allowing for too much time to find a room for the night

Worst experience ever. First time and last time with Ryanair. I'm not a cow.
