I’ve now tried all the A380s and the experience though different has been pleasant.
I’m not inclined to try the BA one which has nothingn new to offer, tired overcrowded first and a business class product that is seven or eight years old.
I don’t think any airline has launched the A380 without at least one new premium cabin, most managed two. As for all the nonsense being spouted about the increased weight version, what difference will it make to passengers? Oh, I’ve just realised, none at all, they will still be sitting in overcrowded first and dated business class.
