Horribly uncomfortable seats. Too narrow.

I've been flying with Virgin Atlantic for 25-years and I still think they are the best airline. I have great respect for Richard Branson. Overall, a cheery modern vibe and good service. Food better than most airline food.

I did not order a vegan meal before the flight and they ran out of vegetarian meals by the time they got to me. The staff worked extra hard to track down something I could eat for both dinner and breakfast. That was really above and beyond since I didn’t order the meal I required a head of time. I was very thankful.

Cold hard biscuit for breakfast was a disgrace

The atmosphere on this he plane was great—especially the carefully planned lighting to help the passengers acclimate to the time zone we were heading toward. A very creative helpful touch!
