Easily the most comfortable I've ever been in TATL economy. Lufthansa's 747-8 is set up strangely: the main deck is arranged First - Business - Economy - Prem. Economy - Economy. This means that if you can book a seat in the forward economy mini-cabin, you get dedicated cabin crew, no other passengers walking through your space to get to the bathroom, plenty of bin space, and – best of all – a lot of aisle space to stretch your legs. Row 16 aisle seats are especially good, as the bulkhead between J and Y doesn't extend all the way, and therefore you can stretch your feet out. Food was actually excellent (for economy), hot and flavorful and generous, with snacks available mid-flight. Beverages also tops – gotta love Lufthansa for offering Campari (!) and more than one wine choice.

Entertainment (music and movies at least) was up-to-date but not very interested. Boarding and transit security in Frankfurt was anxiety-inducing – between getting to the US departures area and additional screening, it took more than an hour from deplaning to getting in line. Boarding w/o group numbers was an exercise in patience. And the terminal wifi is so spotty!

Once In London, we were told by British Airways that was flying us to Nice that Delta had “lost” our infant electronic ticket - It took 1.5h to get new ticket reissued! We missed our connection and had to wait 3 more hours for the next flight - We were somewhat lucky as multiple flights were delayed/cancelled that day - I will avoid using Virgin Atlantic in the future as they need Delta and British operate their flights and this makes it prone to issues like that

Crew was courteous and polite! Entertainment system had some great movies at no additional cost.

Poor communication between delta, KLM and Air France meant that I couldn’t check in online and get a digital boarding pass. Furthermore I couldn’t use the check-in kiosks because my name was listed as Reidmr instead of Reid, which meant that my boarding pass did not match my passport. Overall this caused unnecessary delays that were compounded by the fact that I couldn’t use my TSA precheck. My main problem on the plane was that I had to struggle to get water served to me. It’s always so dry on planes and I would have liked to be able to get more than one tiny glass of water at a time. Also, would have loved a window at my window seat. Plus no WIFI!?

una valija se perdió. Eso desató el descontrol que tiene KLM para seguir el equipaje. No hay como hacer tracking. No hay un teléfono a donde hablar, la web está desactualizada y con información equivocada. Direccionan a usar canales de twitter y facebook que no responden. Primer experiencia en KLM y no pienso nunca más usar esta aerolínea. Llevar el equipaje o resolver un problema sobre valijas es de lo más básico de una aerolínea y no lo hacen.

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.

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.
