While i have no data, I personally find the European airlines to have difficulty with on-time performance. The skies are very crowded and so ATC is a problem. Also, there are many airports (FRA, for example) where most shorter flights are all on the tarmac and the pax bussed to the plane. I have even landed at FRA in a 747 and been met by a line of 4 busses! All of this takes time.

As for bags, AC is very good IMO. Only once have mine gone missing, and I had checked in late (15min before departure). The bags were delivered the next day, but I was at least partly to blame.
