Further update:

TLV-JFK on El Al. As it was a Delta code-share flight, I had both the FlyerTalk tags and Delta priority tags. It was a jumbo jet and my baggage was not in the first 30 or so to come out but it did beat all the Coach Class luggage (I was in Coach).

JFK-PBI on Delta. My bags were the third and sixth bags to come out. This was especially interesting as Delta has gotten rid of priority baggage handling on domestic flights.

PBI-ATL-MXP on Delta. I can't tell you exactly when my bags made it to the carousel as I was still going through Passport Control but they were waiting for me -- while others were still coming out.

MXP-BUD on Malev. No Delta tag, just the FlyerTalk tag. One piece of luggage and it was the fifth off the flight.

BUD-MXP on Alitalia. One piece of luggage -- and the very first one off the plane.

Again, on all of these flights, I was in Coach. I can not believe that this is just coincidence. I am certain that tags stick out more than normal priority tags and the baggage handlers react accordingly.
