Just want to chime in here to say how blown away I have been by these reciprocal benefits. I received Alaska status through a status match and have a 100% upgrade percentage, mainly flying MIA-JFK-MIA on $49 fares in each direction (even with companions). Now that the upgrades are being processed in advance, I have gotten a Flagship First seat the last few flights. Best deal in the skies. There was also one instance where I got dropped from the upgrade list due to a same day change, and the check-in agent was able to add me back onto the list as a "Platinum Pro" member.
