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: Although there were delays they kept us informed on a regular basis as to what to expect and seemed genuinely apologetic for any inconveniences. Boarding and deplaning were smooth and efficient. I really appreciated that there was no charge for checking a bag. I am certain that contributes to the ease of everyone getting on and off the plane. Our bags arrived at baggage claim about the same time we got there. I would definitely fly with Virgin Atlantic again.
