I'm going to lose my Delta status (it was a good run, Delta. Don't believe the haters!) so leveraged my SkyTeam Elite Plus into Turkish Elite for *A Gold for 2 years. The Turkish status match went through less than 72 hours after e-mailing them a copy of my Delta Medallion card and statement. Didn't receive any notification but logged into my Turkish account and it now shows Elite. So easy! I've scant experience with Star Alliance carriers and am US-based. Delta's been a fine option for my domestic flying but not great for my increasing frequency of flights to Africa so I plan on throwing my business to *A carriers after March. Any pearls of wisdom from old *A hands? Thoughts on US Air vs United for domestic flights?
