Klm start boarding while somw air issue in the plan

The service was great. However the lounge only gets passing grade

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

You should not have to pay for WiFi in business class

Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

They only had vegetarian food left on the flight which I wasn’t happy about. I didn’t get any food to eat at all.

I would definitely use a Linus again, the price was right, the service is excellent. No delays. Wish I had a direct flight from my hometown Detroit.

There was no room in the seats, smallest room we've ever had and the food was awful.

I dont fly them much anymore. Other carries offere better pricing and better seating options

Seats weren't very comfortable for a long haul flight but the service made up for it.

This flight was of exactly the same high standard as the outbound leg, exactly a week earlier - except that we didn't have any food or drink because it departed at around midnight.

The Glasgow to Dublin route was very efficiently boarded, flight and landing and disembarkation were all super smooth. Dublin to JFK flight I was very pleasantly surprised overall. This was my first time on Aer Lingus and having already come off the short regional flight I was curious to know how the international flight would go. Aircraft was solid, entertainment options were better than expected, flight crew were experienced and operated like clockwork. Main entree left a little something to be desired but the snack was very tasty. Boarding and disembarkation again very smooth and pilots got us in earlier than expected. Would definitely fly again

Unfortunately the flight was delayed for 50 min. Just as we were about to board so that was a drag. The boarding was average. The bag check in process was new to us and efficient. And the flight itself was smooth- basically no turbulence.

I liked how they looked after couples by providing a row of 4 seats if available.

Food was very bad. Boarding was disorganized and messy. Crew was friendly

I believe it was short flight in plane I understand not that much compared to other airlines but weighting for checkin was too long need extra person for checkin or Atleast someone to let the customer knows don’t worry someone will be here shortly.
