Though I much prefer Boeing, this order was not cancelled because of quality issues, it was cancelled because of trust issues. Airbus said, "Can you wait a bit longer for this plane?" UPS responded, "Maybe. Let us run some numbers." Airbus then started taking people off the project. Ergo, they were lying to (and screwing) UPS in order to get their passneger orders filled. UPS decided not to be treated like their dog.
Seems to be a EU thing anyway. They hate our guts.
And also, no matter how good the product, there is always an auto dealer around where you live where you would never do business. Attitude.
