Stood at check in for over 30 mins with no staff in sight. Boarding was a disaster. Staff was not prepared nor organized and the crowds were unbearable. Upgraded seats were laughable and not worth an extra $60. Food was mediocre. Entertainment would have been good but GE touchscreens are so old, they were difficult to work.

Right before boarding I checked to see about purchasing an upgrade to business for my Wife and I because she was not feeling well and the added room would help. The Rude desk clerk didn’t even check and just spit out no upgrades. Yet once on the plane there were several empty business class seats and they stayed empty the entire flight.

The Lufthansa crew and planesnare always top notch.

Long wait time to board, delay of approx 40 min without any update on what was happening. I believe however that is not the fault of Lufthansa crew but rather the SJJ airport staff. I also have one star for entertainment bc there is no option for “not applicable”- this airbus was not equipped with a television or other entertainment options as the flight length is merely an hour.

I can’t say enough about the Lufthansa staff- we ran to our gate because our connecting flight was late, and we were greeted by a warm and smiling face who said “It’s alright, don’t run, take your time, we’re waiting for you.” Onboard the crew was phenomenal- Every. Single. One. I have always felt as a burden to crew if I asked for extra water or an extra blanket- not on this flight, not with this crew. They came around multiple times per hour during an 8hr and 20min flight, offering various beverages and checking on everyone. I can’t thank them enough for how caring they were to everyone on board. The captain as well was very professional and had a kind spirit when he spoke. Best experience I’ve ever had- (and I travel multiple times per year!)

The plane is not comfortable. Especially the number of toilets is very small: only 1 (ONE) on each side in the touristic part. And it is on the flight London-Las Vegas (10 hours)! One has to go for taking some drink himself. Not enough drinking was suggested during the flight. The screen is very bad. No real choice of movies.

Great crew who managed brilliantly under the circumstances....

The aircraft was unbearably hot - crew member in rear economy member said it was 42 degrees at one point. Took almost 2 hours to get the back of the plane (where I was sitting) down to 27 degrees. Understand that temperature can only be reduced in small increments but why was the temperature on board allowed to get to 42 degrees prior to boarding?? The crew were brilliant, and hats off to them for working in such difficult conditions.

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

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 rentals 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.
