I choose Lufthansa cause it’s a good airline with great quality but this one was soo old and poor. Food was terrible. Blankets and pillows very old, looked like they were like used. The chairs were soo uncomfortable

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.
