Ultimately I consider business class to be primarily about the seat, and that’s just where American shines. I prefer them over British Airways, Lufthansa, Delta (I haven’t yet flown the new Delta One suite headed mostly to Asia), KLM, and I prefer them of course over Air France’s angled A380s though not their reverse herringbone direct aisle access 777s.
They offer really good seats and functional internet. And my main meal really surprised me by how good it was. They’re also improving the bedding.
