A reasonably comfortable flight in cattle class - 747s definitely have more legroom than 777s.

Very young cabin crew. A bit of a lack of leadership

Main meal was missing starter, butter and cup. In-air service wasn’t as good a Virgin Atlantic.

So much better having a new plane compared to my last BA flight which was horrible by comparison. I don't like you have to pay in advance to reserve seat though and so has stopped me from doing this.

Flight was fine...actually felt like a shorter journey than it actually was (even though it was over 10 hours). Thanks B.A
