Pros: Cabin crew were great.

Cons: Was almost impossible to make this connection. Honestly I probably should’ve been moved to yet another later flight. Ground crew said my bag had made it on board, so i waited and waited but it never showed up in Kraków. Lost luggage team was helpful and told me it didn’t make the flight - it was on the next one. Hopefully it gets delivered soon but it will be difficult bc my air bnb has no buzzer

Excellent 10.0

Pros: I was amazed how comfortable we were in economy. Pillows, Blankets that felt like cotton. I would fly Lufthansa over an american carrier any day. We passed through the business class cabin on the way out and I can only imagine how much they were pampered!

Cons: Since flying in the US has become expensive and painful I was not expecting much from this flight. They exceed my expectations by so much that I cannot think of anything I would change. (Ok, my chicken was a bit over cooked but that was such a minor thing.)

Pros: The pilot told the passengers before the flight took off that there would be some turbulence. It was nice to know about it beforehand

Pros: The crew was extremely efficient in everything they did. Beverage service was super but many of us didn't know we could get our own from the front of the plane.

Cons: The seats lean too far back and are hard to get in and out of. There's very little space for anyone in the middle seats to move, much less climb out from. Oh, it was never clear to the passengers that anyone could get up and get drinks from up front during the flight.

Cons: Worst possible gluten-free meal. Other airlines do it better. One CFAN make a sauce to put on chicken - it doesn't have to be boiled or microwave into a piece of rubber, with plain rice and a couple of boiled carrots. This isn't just gluten-free, it's complete allergen-free which is quite different

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.

If you have more questions or if you have a bad price to report to us,
