In business class overhead bins were minuscule. Had to use cabin staff to find a place for my carry-on bag. Boarding process was shambolic, as “passengers who needed assistance in boarding” absorbed an excessive amount of time and attention that Aer Lingus was apparently unprepared for.

In business class overhead bins were minuscule. Had to use cabin staff to find a place for my carry-on bag. Boarding process was shambolic, as “passengers who needed assistance in boarding” absorbed an excessive amount of time and attention that Aer Lingus was apparently unprepared for.

Aer Lingus was fabulous.nhowever, Aiirfare Assist who Kayak routes me to to purchase tickets for m was awful. They messed up my reservation so bad that after about six hours on the phone with them over the week before departure, I had been choice but to show up at the airport. The Aer Lingus staff were amazing and got it sorted out but I would recommend not using Airfare Assist.

I had a great experience. I wasn’t sure what to expect but the crew helped me check my bags and made sure I got in the correct line to board. It was a bit of a walk to my gate so arrive early. I would recommend securing a flight that includes checking in your bag if you remotely think your baggage is over 10kg/22lbs. Be safe and upgrade unless you are carrying a backpack or weekend type baggage.

Dublin to Boston was decent. Food and entertainment was included and that was expected for the rate paid.

No entertained. food and beverages were not complimentary. they lost my checked luggage which made my 10 day vacation unpleasant.

Flight was on time. Boarding was quick and efficient. Seats were comfortable. Food was fine.

I like Aer Lingus so that is why I’m writing this critique so they can become better. The boarding gate was too small to board properly. Our seats were toward the back of the plane knowing we would be boarding after business class, we moved to that area after business class boarded. An Aer Lingus employee told us we couldn’t stand there. We explained we were the next group to board and wouldn’t even be able to hear when our boarding was called. She didn’t care and was not very professional. The cabin was freezing. I wouldn’t feed my dog the food. We were over an hour late coming into chicago because of weather which can’t be avoided. I asked the crew if they could make an annoucement for before whose final destination is chicago to wait and allow the people with connecting to deplane first. He said there are a lot of people with connecting flights. He said, it doesn’t matter. Well, yes it does. He could have been more considerate of his passengers.

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.

The seat spacing was good. The food, not so good... typical airline food. 😕

I would face like to have more selections for entertainments overall it was very good. .

Very good experience. All of the details made this experience very positive.

Business class was roomy and comfortable however, the entertainment screen was very dark and hard to see.

Flight LH760 from Germany to New Delhi, the food was excellent, the crew was fantastic, the seats in economy are usually tight these days, so I can say that the seats were Ok, the entertainment was OK because for some reason the sound is not very clear, overall I enjoyed this flight, compared to the flight (UA 962) I took with united from San Francisco to Frankfurt in this trip, that flight was horrible. Thank you Lufthansa.

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

Very helpful crew, including airport people, getting us in wheelchairs and working so hard to get us where we need on time!

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

Overall excellent service and Frankfurt Airport was very efficient and clean

The boarding process was really slow. The air crew was amazing and the food options and the entertainment were also really great.

I came out early, 4 hrs before departure. The flight was changed 4 or 5 times with few minutes between new and schedule time , then 30 minutes delay, then up to 2hrs 30min delay. When I arrived in Frankfurt, no one help us to lead to the custom service. After almost 1 hour asking around then we must line up for another hour to get overnight and rebooking the next flight. We must find out how to get to the hotel by us self. The shuttle bus driver in Germany was not nice, speak German to English speaking and we must predict what she / he tried to tell us. We got up earlier and tried to not coming late to the check in and immigration procedure (we were told by the helping center that the immigration used to be over crowded) then we came there it was almost empty, then we must stay in the airport for hours not necessary. We got the coupons at the airport for compensation for waiting for delay flight for NOK 75 ( as low as 6 Euros) It is not enough to buy food at the airport price and Norwegian cost of living... How to drink a cup of cappuccino for NOK 72 when the stomach was empty for food in 16 hrs (from dinner at 6 pm the day before to 16 pm the day after) At the hotel in Frankfurt, we were offered two options spaghetti with biff or vegan food and a drink for 18 Euro. Almost 60 passenger ate the same food and I was remembered once time in former Soviet Union in 80's I travelled with Aeroflot and the passenger were stranded in the hotel for next flight and we were also offered only one choice of dinner, if we were hunger we must pay 1$ for 1 egg and another 1$ for two loaf of bread and butter. I can't believe Germany is to poor and inferior service like former USSR in 1980 decade. My good remembering of Luft Hansa disappear and changed totally by this service I got this time.

Disappointing. Too many let-downs, in delays and communication, by both Lufthansa and Discover to put in an email. I am resigned to the fact that this is what I should expect from all airlines. Unfortunately.
