Well that's exactly what I was wondering actually, people seem very keen on AB and I was wondering if it was some kind of EU pride or what drove people to care so much.
probably both... EU people like Airbus as well as American prefer Boeing or Canadian prefer Bombardier.
But from an objective standpont, I truly believe that Airbus A320 family is excellent, as well as B737. But the NEO version is adding significant value for airlines.
As for LH, A330 is great, B777 as well. A380 is great, but I doubt B748 is matching the challenge (luckily it is positionned on another market than the A380).
In the end, I believe Airbuses are more stable (hence feeling of safety for passenger increased), silent, less consuming for similar weighting,... However, I have some friends in the maintenance department who consider Boeing as safer since it still uses mechanical commands. B747 is incredibly safe as a plane.
Both brands are providing great products. My preference just goes to Airbus, but this is not because I would reject Boeing.
