All very good The food definitely lacks quality and at breakfast I was given a small muffin small orange juice and not even a coffee or tea were offered It would have been nice to have that first thing Apart from the food everything else was excellent

Everything is good, but my luggage was damaged. How are you guys gonna pay for my luggage?

It was poor overall. They cancelled our flight and changed it without notifying us. So we incurred extra costs by having to book a hotel for our layover. They say it's Kayak/Underpricer's responsibility to reimburse us. But Kayak/Underpricer have said it's Aer Lingus' responsibility because they are the ones with our 'booking information.' I find this situation confusing and unacceptable.

Staff was generally friendly and helpful. Attendants collecting trash were somewhat inattentive though.

It was my first transatlantic flight with Aer Lingus. Very enjoyable. Thank you for making international travel enjoyable again.

Everything went well. I made my connection which is always a concern.

The flight was delayed by about an hour, but the staff and signs at the airport never actually said it was delayed. At the expected boarding time, we were told we would be boarding in about 10 minutes, then 20 minutes passed, and were told again that we would board in about 10 minutes. That happened multiple times, such that "10 minutes" turned into an hour.

Both flights were delayed due to maintenance issues. Because they where late boarding all four of our bags where left behind on our last connecting flight.

Staff are so nice and friendly, plane was very clean and plenty of leg room

It has nothing to do with Aer Lingus and everything to do with Frankfurt airport. There eere no visual displays of the flight destination at the gate. They kept changing our gate with semi audible public announcements and eventually I was at the wrong gate and my flight departed from the other gate.

Huge wait to board after waiting for 2.5 hours delayed flight

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.

On time boarding, on time departure and early arrival. As it should be. Yes, the comfort and benefits are very poor, but therefore the ticket is 6 times cheaper than with a flag carrier. So I am not complaining about it. You get what you pay for.

We missed the flight due to very slow security control and lack of last call announcement. We only found out at the gate that the gate is closed. Altogether 14 or 15 people missed the flight FR4500 from Cologne to Dublin.

It was a short flight. I don't really have any notes. You bring your own entertainment but as long as you aren't boring or forgetful that's not a bad thing. There were snacks and they gave me chocolate before we disembarked!

Proximity of the the gate to the lounge could have been better but overall a nice experience. The lounge was exceptional. Getting from the Schengen side to the international side was also pain free. Boarding the plane, service on board , disembarking at Heathrow and quick delivery of bags all made for a good overall experience.

Such a comfortable flight! Food was yummy and staff was very friendly! Will absolutely fly Lufthansa again.

Again another extremely chaotic boarding for the flight. Could have easily opened up more automated gates and the staff could have proactively managed the queues as they're forming rather than sitting behind the counter, waiting for the boarding to start.

There was a stewardess walking up and down and keep spraying room refreshner on people heads and faces. I had to bread this and smell like a room freshener afterwards not to mention was keep falling on my face. It was terrible.

The food was fine. The seats are small but accomidating. The staff was very freindly. I would fly them again happily

My flight to Frankfurt was a very pleasant experience. The food was good, but what really stood out was the cabin crew, who were exceptionally friendly, attentive, and professional. The service was excellent—honestly, better than on some much more expensive flights I’ve taken. A wonderful experience overall!

Overall excellent service and Frankfurt Airport was very efficient and clean

Terrible experience. I was stuck in Germany for two full day because your flights can't leave on time. You guys suck!!!

Didn't have bar code on our phone based boarding pass. People at the counter didn't notice. We walked to security, couldn't get through, had to go back to check in to get a paper boarding pass.
