Per usual, KLM can't seem to figure out the order of boarding the plane. Should be business - priority - everyone else. Instead they do priority first, and that's usually two-thirds of the passengers. Strange choice of in-flight movies; no accounting for taste, I guess.

Excellent 9.0

Lufthansa pilots are some of the best in the industry and the flight was extremely smooth from take off to landing. There were bouts of turbulence but the pilot immediately changed altitudes to steer away from it. Flying on the 748 is a pleasure and it's a shame these great planes will eventually all be phased out in favor of more fuel efficient 787s and their Airbus counterparts.

Having to pay 86€ for a second suitcase that weighed just 15kg. In JFK they didn't charge me but Germans always go by the book. I think for the price of the ticket and lower gasoline costs compared to the height of the recession this is simply outrageous. Next time I'll pay for economy plus. You get a seat that is wider than economy but a little bit less legroom than a business one and the second baggage is included. The meal was nothing special but the friendliness of the flight attendants made up for it.

I flew in an A380 from LAX to FRA and that is a huge airplane but very nice. The flight from FRA to TLV was full and that airplane had no USB charge ports and no seat back video. I refuse to fly El Al because they don't have video and charge ports. Now I need to avoid flying with Lufthansa.

No USB charge ports and no seat back video. They only have movies from Sony.

I had a 17 kg big baggage and a 7 kg hand baggage and was forced by the hungarian check-in attendant to pay the equivalent of 112 usd.

The British airline flight was operated by american airline and someone who handled her bag stole everything. We purchased prior to the flight. 2 pairs of sneakers a gift spoon for our grandson and other items not mentioned. Then they put her bag on another flight which made her wait for 1.5 hours in Madrid for her bag. Your handlers ruined our trip.How can you allow thieves to do this especially with TSA supposedly there monitoring it? I want a claim form sent to me ASAP so I can recover my goods. A notice was not placed inside, stating it was checked.

I bought a ticket for three persons: my wife, my daughtet and me. I am Nigerian, my daughter American, and my wife's Turkish. However, because of the diplomatic row between Turkey and the U.S., my daughter was refused entry into Turkey. Turkish airlines' policy was to refund the ticket of any American caught in this row. They said they will refund my one month old daughter's ticket. However, my wife and i will not receive a refund. We bought the three tickets together. Our ticket numbers ended in 235...51, 235...52, and 235...53. However, they will not refund our whole money by cancelling the ticket but only that of my daughter. So this is the question: Does Turkish airline want me to leave my one-month old baby in the U.S. and tavel with my wife to Turkey? What kind of parents will we be if we were to abandon our daughter to take a trip to Turkey. Even, the people in Turkish airlines will judge us evil parents, yet that was exactly the only option they gave us. Lose your daughter or lose your ticket money. They will not even just change our iternary or give us another destination we suggested without penalties which are almost 3/4 of our initial ticket price. They just made away with our money. You cannot say, 'We are cancelling tickets for American citizens' but make no exception for parents of infant citizens. This is the height of criminality. So, me and my family couldn't take the flight and lost $1500. We had to buy another ticket by airfloat to get to Georgia. But Turkish airlines refused to even contact us on the refund for my daughter. A truly criminal enterprise.

They had a vague refund policy for Americans, forgetting that American infants can also have none-American parents who are as much victims in this as the American infant. For them to be myopic and keep repeating talking points of their refund policy is unfortunate to say the least.
