We arrived at airport around 9:30 AM and checked in by 10 am! Later we were informed that flight was 20 moms and later our flight being delayed by an hour and 10 mins. The arrival gates changed twice ! Plus traveling on the bus to and fro at both delayed further! This Placed an additional pressure on us in Dublin as we had to rush, run and clear both security and US customs. Where both sides were extremely busy with other flights to US. Luckily we boarded our LA flight just 5 mins before take off! No time for bathroom breaks or any shopping! Instead of relaxing flight it becomes more stressful due to timing and delays!

First leg of my flight: flight attendants - not very welcoming & also ran out of the snacks that should have been included on my flight. (I did not receive anything during flight because they said nothing was left - only things to pay for) Shouldn't they have had enough for all the people on the plane? Also, my seat, window and tray table were filthy - I had to clean it myself before sitting down. Second leg was better in terms of cleanliness - but honestly, both planes were really not clean (bathrooms included). The hot meal was pretty gross. But the canned wine was fantastic and felt elevated. No blankets, only pillows and plane was freezing cold. Pilots were great and landings were even better! As a frequent flyer... this was my first time flying with aer Lingus in many years and I have to say... I don't plan to fly with them again any time soon. I was overall disappointed.

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.

The Linate Milano flight was delayed. Landed at Frankfort at 12:10. Then took the bus on the tarmac and the bus ride was about 20 minutes due to the airport traffic. Got off bus went to passport control, used the kiosk scanned passport, took photo and finger prints and proceeded to wait in line. I asked the attendant that I had a connecting flight at 12:50 his respond was you have to ask the other travelers in line to let you go ahead. There should be a better system. Passed passport control and the gate was at Z69 to the other end of airport. Ran there out breath, I was last person to board due to a mechanical:electrical issue plane took off 2 hours later. Lufthansa need to a better job with international connecting flight. A 1-15 minutes is not enough considering the doors typically close 15 minutes prior to take off. So the window is reduced to 1 hour with all you have to go through with a slight delay it is not enough time. The crew on the flight was excellent and received exceptional customer service.

Keep an eye on your seat assignments - ESPECIALLY if you paid for upgraded seats - the airline moved us out of our prepaid seats THREE TIMES and I could only resolve it by calling customer service - who was very helpful. Expect to carry your bags down several flights of stairs for boarding on the tarmac.

It flight had a maintenance issue, that should be part of of preventative maintenance, and then they completely mismanaged the passengers on the buses. A terrible experience.

Absolutely horrible. We missed both of our connecting flights from Frankfort due to the new border control lines. Lufthansa had us running and walking around the airport trying to rebook. They were not prepared to offer us a hotel room for the night, but finally relented when I said I was done with Lufthansa, most were not so lucky. I also put put of the blame in Kayak. You need to update which connecting flights you are offering to allow for more time to deal with the mess that is border control in the EU.

Connecting in Frankfurt was a nightmare! Whoever scheduled our connection in Frankfurt for 90 minutes should be fired! Passport control takes 3 hours, minimum! Avoid Frankfurt airport at all costs! Never again! The airport is 3rd world. The WORST!

It was ok no problem on flight after the ordeal with passport control. Long line and nasty officers not very helpful.

roomiest flight in economy I've taken in years. Excellent experience!

I was disappointed that paying nearly $5000 more for business class for two didn’t really get me any more than a larger seat which as the last row in cabin reclined only mildly and the foot supports were of minimal help and left no room under seat ahead for carton bag. Second, our checked luggage was lost and took us two long days and we’ll after midnight each of them and multiple calls and 30 euro trip to airport in person to finally get them. Would you do this again?

I bought premium economy tickets with a fully flexible fare, and made seats selection for me and my son: window and aisle. After checking in online, Lufthansa cancelled the seat assignment without informing me. As a result, my son and I were assigned mid-center row seats, in different rows. This ruined the trip.

Overall excellent service and Frankfurt Airport was very efficient and clean
