Well, I must be doing something right. 44 of 48 mainline flights this year have been upgraded.

The four that weren't upgraded were LGA-ATL, ATL-PBI, DEN-SLC and SLC-SAN. DEN-SLC surprised me, although as there is no gate display I was kind of in the dark anyway. The SLC-SAN that was not upgraded was only because, according to the SLC gate agent, the check-in lady at COS didn't put me on the list (I did request and she replied in the affirmative), plus I volunteered, but they didn't need anyone. To add insult to injury, I lost my nice window seat and got a crummy window seat over the wing.

Of the 48 flights, only 6 were to/from Florida. ATL-PBI was an MD80 and the other 5 that were upgraded were 767's from MCO or TPA.

So, maybe the key is don't fly to Florida unless you're on a 767!
