Normally I hate these kinds of targeted promotions, and even posting them, but this could be a nice perk for some in the NYC area if you qualify (as you can see my wife did NOT living in Indiana).
Now Gold Medallion status is not all it once was, and I would NOT:
“purchase and fly one qualifying, paid Delta One™ (fare classes J/C/D/I/Z) roundtrip transoceanic flight offering Delta One service during the Promotional Period”
to keep my Gold status unless my company was paying for the ticket. There are MUCH cheaper ways to get Gold Medallion status like getting a personal and business Delta AMEX Reserve cards and spending at least $60,000 on one of them. Then you are Gold medallion with 50,000 total MQMs without even flying.
However, the two months of Skyclub individual membership could be very nice if you are going to be flying for the next few months and the temporary Gold medallion status will also get you Skyteam lounge access in any class of service when you are outside the USA! – René
