They are terrible at maintaining it though... Things break and remain broken for months. Customer service is non-existent. Then they "fix" programs by removing everything useful about them (e.g. Lufthansa was no longer refreshing and they "fixed" it to show status miles only, but not reward miles; when Auto-login stops working, they simply turn it off). They have the same programs entered under many different names to make it look like they have more than they really do; many programs are simply not there (SW, F9, etc).
