The booking I made 2 months in advance got changed the week before with another flight and had to pay more for seats and luggage. Not to mention hours and hours on hold to make sure my flight is still booked.

The booking I made 2 months in advance got changed the week before with another flight and had to pay more for seats and luggage. Not to mention hours and hours on hold to make sure my flight is still booked.

It was very good, good food good stuff, The toilets were a little stinky.

They gave us chocolates twice (for whoever would like an extra chocolate - kids did!). I asked for an extra water, and I was given one. Crew was very friendly!

I bought a ticket and paid for for our luggage but I had to pay for my luggage again. I’m so disappointed! We had a 30 min delay and because of that we missed our connecting flight and were told that we would be on the next flight (9am flight ) but we were landed we were booked at 12pm flight. I had a little baby w me, it was very stressful. I begged to leave at 10 am at least. I was emailed that we get a voucher but they didn’t work when we were at a breakfast store. I’ve been always happy w Lufthansa but this time was awful.

Good service … bus transfer upon arrival from plane to terminal: atrocious!!!

The media system is so inreliable, it keeps freezing and restarting at the begonning. Old planes with an old entertainment system makes a long flight very boring

When I booked the flight with Cheap Flights I actually booked in Business Class. When I got the confirmation it showed that my flights had been purchased by Cheap Flights in Economy Class with an Upgrade to Business Class. At first I was surprised and then the problems started. If you are not a seasoned Traveller you would not have been able to handle the issues this created. 1: the lay over time for the connecting flight in Frankfurt was 45min, which is extremely short and even the slightest dealy would have resulted in me missing the next flight. 2: the checked baggage allowance in Buisness class is 2 bags/ ea, 32Kg., however, my ticket being booked in Economy with an upgrade to Business only allowed for 1 bag/ 23 Kg. when I did the online check in my Boarding Pass showed a checked in Luggage allowance of 1 bag/ 32 Kg. which was very confusing. I called the Airline and asked what my checked in Luggage allowance actually is and was told 1 bag/ 23Kg. Since I have a frequent Flyer Status with the airline my baggage allowance increased by 1 bag / 23Kg. When I arrived at the airport I asked to be booked on an earlier flight, in order to avoid the stress and possible missed connection and I was lucky that this was possible. If this had not been possible, I would have missed my connection due to weather and even I am not quite sure, if and what the consequences of my cheap ticket would have been. My point being: if all of the above would have happened to an unsuspecting/unseasoned traveller, this trip would have ended in a disaster. The issue with the pricing is that the alledged money my airline received and what I actually paid to Cheap Flights shows a $1,000 difference. In conclusion, I would stay away from Cheap Flights if you want a hassle free experience!

The boarding system was all bogus - employees at the boarding gate were not sound like proffesional or may be possibly rational

This is my second time to fly this year with Lufthansa and both times they dropped the ball. My ticket was very cheap and l would not be honest if l said that l had some high expectations for that price. Fly delay 6 hours. Screen in fey seats around me didn’t work. Food for dinner was ok but breakfast was so poor. We had connection in Frankfurt for Vienna. Because of delay they gave us fly with 30 min layover time. We got to Vienna but our baggage was late of course. Long story short it took us almost 24 hours to get to the final destination. Very bad experience

Good but entertainment system was not easy and very buggy
