Never took the flight due to strikes which happens but there was no timely coordination to find me new flights. I had to call Lufthansa and Kayak support only to be given no good options and a 75% refund. Ended up spending way more for alternative flights that I coordinated myself for a trip I had booked 6 months prior.

Never took the flight due to strikes which happens but there was no timely coordination to find me new flights. I had to call Lufthansa and Kayak support only to be given no good options and a 75% refund. Ended up spending way more for alternative flights that I coordinated myself for a trip I had booked 6 months prior.

Come on. A two hour, 7am flight and a small bottle of water and a tiny chocolate bar was provided. No coffee, no nothing. Poor.

Plane was crowded, seats narrow, legroom nearly nonexistent. The entertainment feature didn't work for my row and nobody was able to/interested in trying to repair it. This flight was in direct contrast to a very comfortable Lufthansa flight from RDU to Frankfurt about a week earlier.

Rushed due to connecting Lufthansa flight delay Seating very tight and uncomfortable with poor leg room Long lines for rest room

The food was straight up bad not gonna lie, seats are uncomfortable so I had to re-adjust my self most of the time, delayed our arrival time by alot.

Better when flight announcements are better produced and slowed down a bissele

My only complaint would be that we paid for insurance in case we needed to change our flights. However we still had to pay to change and was not helped on either travel parties. I would like a refund for my change fees as indicated in our insurance plans.

Le personnel attentionné et trilingue, la tranquillité du vol. Aucun aspect négatif

The only really annoying part was the TV screen. It was kinda messed up. Like it would just randomly turn off or switch. It was also not responsive. Which gets annoying on an almost 12 hour flight

Wasn’t overbooked, so it was nice having an empty seat next to me. Appreciated the on time flight. Food was really bad though. Received stale vegetarian sandwich with just a slice of cheese and shredded carrots on it. Very strange and not tasty. I didn’t order a vegetarian meal either way of my trip but received all vegetarian meals because they said that’s all they have available.
