The crew was first rate. They allowed me to switch my middle seat to an isle seat and it made my flight home so much more comfortable.

The crew was first rate. They allowed me to switch my middle seat to an isle seat and it made my flight home so much more comfortable.

Everything went very smoothly I loved having the earphones and the blanket and the staff was just super friendly

I was advertised a free seat selection for a "Smart" fare through BusinessClass.com. I was never able to select a seat. I thus paid extra for a bill of goods I was never provided. would love to speak with a representative of Kayak

Overall good. We weren't able to find out about food options for the flight and there was nothing I could eat due to allergies. The biggest problem was getting our checked bag at Logan. Waited an hour!

I loved both of my flights to Ireland and back to Boston. The only negative was it took over an hour for the baggage to be delivered.

Customer service was excellent! The app was terrible, tried several times to check in without success! But the young lady that checked us in was absolutely terrific and helpful.

Horrible. I had to wait in Dublin for 4 hours for the next connecting flight which took my to London and than i had to wait 3 hours for the flight to Dusseldorf

Was not aware that Aer Lingus was like the cut-rate services in the states, with no food or beverage (other then 3.50 Euro coffee) and no screens for entertainment. Was a great flight, but not much in the way of services.

I didn’t realize Aer Lingus was a “nickel and dime” kind of airline where you had to separately buy all the amenities you wanted. The push to purchase duty-free beauty products was off-putting. And our row had the least amount of leg room I’ve ever dealt with on a flight.

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Lufthansa was great. Crew on board excellent. Frankfort passport control horrible it took about two hours to get through. After waiting in line for hours there was a discussion with the passenger in front of me that was taking forever. The couple behind me had a connecting flight to Turkey in 30 minutes and asked border control officer of her situation and the control officer told the couple in a nasty tone if you don’t like it you can go to another line which would have surely made her miss the flight. Border patrol officers were not helpful. Finally made it through I had to exit and reentry for security check for my connecting flight which Lufthansa changed gates and I had to run to get to A60. Which it seemed 2 kilometers to get to but I made it. If i fid not have 2.5 hrs layover i would have missed my connecting flight to Milan. Not sure if I will fly through Frankfort in the future.

3 4 3 seats are cruel, the average person should be able to fit in the seats and this was not the case. I was at an angle for hours just to remain in my seat .

This was a "cattle car" flight loaded with the tightest seats I've ever flown internationally. I will try hard never to fly Discover Airlines again.

Lost our luggage, now two days and four $30 each taxi trips to airport and long lines in taxi queue because Lufthansa didn’t get it right, by not recognizing new delays between flights caused byEU new lengthy crossing requirements for non EU travelers, so luggage lost because traditionally methodical and orderly Germans not paying attention.

The flight on time, flawless check in and boarding process, the crew was very friendly.

It is ridiculous that Lufthansa weighs your carry-on bags. It's also ridiculous how strict they are about the 50 pound rule when you're flying overseas for nearly 3 weeks. The reality is, that if you book a business or first class ticket you get a $70 luggage allowance. It's bullshit that it's not about safety. It's not about regulation. It's about money. And that pisses me off. Furthermore, under price, which I assume was the travel consolidator for my ticket sold me some bullshit ticket that did not include to check luggage. What a bunch of nonsense. That's a scam. There shouldn't even be a ticket offered to Europe without checked luggage. I don't know how most people are, but now I'm gonna be very skeptical about using KAYAK again and flying Lufthansa. I think maybe it's best I just booked with the airline directly.

Crrew great. Seating space getting worse that worse. Food awful

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

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

Staff was rude in business class. Luggage was damaged and nothing was done about it airlines.
