Good 7.3

Pros: Crew, food, and business class pods were super. In fact Lufthansa itself was great BUT read next...

Cons: ...debarkation at SFO was dismal. The nearest bathroom upon debarking was closed for cleaning. The passport control signs were misleading and confusing (the term "residents" was misused). And there was no one at baggage claim to prevent bags from piling up atop each other on the conveyor. I received a bone bruise trying to get my bag off another one. Avoid SFO as an international destination if you can...horrible airport.

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

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 prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons 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 don'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.

More questions or if you have a bad price to report to us
Please send us an and someone from our team will get back to you promptly.
