Pros: Customer service by the crew

Cons: Lufthansa still charges full price like usual, but on a 8+ hour flight to serve a cat size meal of pasta soaked in some pesto sauce is unacceptable! Thank god I had lunch at Frankfurt before departure! Covid-19 should not be an excuse for lack of services! I work for a company which falls into the Essential business category and despite the pandemic we NEVER EVER compromised with the top quality of our product! I am so dissatisfied with Lufthansa and what they have become, pale shadow of a great company, very sad....

Pros: I've never been on a flight with such narrow seat and thin cushion. There was no entertainment offered for the almost 4 hour flight. There was no means of charging any electronic gears. The airplane seems to be 30 years behind time. Crew was unfriendly and smiling faces are not part of the uniform.

Cons: Very narrow seats and thim cushion. No entertainment offered an do means of recharging electronic devices.
