Pros: Friendly, quick and efficient crew! Great food too!! My favorite part when in Houston, Texas my starting point, was that I never had to do the self check in, y’all actually had “real” people going the job!!

Cons: Boarding in order, by the seat numbers. That’s the only thing y’all can improve on. It was my first time booking with Lufthansa, and I will definitely book with y’all again.

Pros: Going through US Customs in Dublin is great, makes The landing home so much easier.

Cons: The airline made people unnecessarily nervous by posting a very early boarding time so people thought they had to jump in line in customs when, in fact, we all had the same departure times and all had plenty of time.

Pros: Not so many passengers so we're all spread out and enjoyed the space and privacy. Got free upgrade to Premier Plus.

Mediocre 2.0

Pros: Your willingness to proceed with flying into a pandemic zone with total travel lockdown.

Cons: allowing travelers that have been advised not to travel to Europe to either change or refund their flights. Your system for this is a bureaucratic nightmare, and the responsible thing to do in a time of crisis is allow people to make the right decision to stay in place. I am done using your service.

Mediocre 2.0

Pros: The only positive with this experience was the gate agent(s) superior customer service. That being said they were stuck with dealing with a complete failure of United to provide guidance as to how the airline was going to deal with a technical issue with the plane. The flight was scheduled for a 7:00 AM departure, from what I could tell the flight finally left Portland around 4:00 PM. Because of extenuating circumstances myself and my traveling companion cancelled our entire trip. Given such a poor start we were unwilling to trust that any proposed alternative would be any better. In other words United seriously dropped the ball. They not only owe an apology to their customers, but also owe one to their hard working" contract" employees.

Cons: Communication. As I explained to United customer service, I find it incredible that the airline industry has built a business plan based on the misguided supposition that everything they do will go according to a best a case scenario, yet they appear to not have much of a plan when things don't work that way. Second, the idea that they have no proactive system to deal with technical issues a smaller destination. There are no mechanics/technicians stationed at places like Portland. I don't know what it cost them to have a revenue producing aircraft sit on the ground for 18-20 hours, not to mention the labor costs incurred trying to redirect 100 or so passengers. It seems to me that those numbers would probably go a long way towards paying to have a mechanic(s) on duty. As an aside, I paid retail for two first class round trip tickets. Given the circumstance I would like to see United refund those ticket prices in full, then and only then, will I consider using their services again.

Prices are per person, are for e–tickets and include all taxes & fees in EUR.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
