I was surprised to discover recently that I am only a few hundred miles away from Medallion Status on Delta. I say "surprised" because I generally don't fly enough in a year to get the necessary mileage for any kind of airline status. However in this case I benefited from a couple of trips to the west coast earlier in the year, plus two sizable MQM bonuses that I received courtesy of my Skymiles credit card. I have some long haul trips planned for later this year and early next, so decided to have a go at a Mileage Run to get the remaining miles for the status upgrade.
Since I'm new to doing Mileage Runs, I decided to try something not too terribly ambitious - just enough miles to push me over the threshold. I've read that ATL is not a great airport to base out of for this sort of activity, but I did find an inexpensive R/T flight to Louisville that departs on a weekday afternoon, has a short layover at SDF, and then returns to ATL by about 8:00 PM on the same day. It cost about $145 altogether and I'll get 1000 miles out of it - not such a great deal in terms of cost per mile, but for a first effort I guess it's not too bad (plus it's a small financial investment if I have to back out at the last minute out for some reason).
Anyway, here's my question. My biggest concern with this is that something will happen in Louisville (delays, etc) and I will miss the return flight to Atlanta. Both flights have the same flight number so I am guessing it's the same physical airplane for both legs. Does anyone have any idea if that's a valid assumption? I figure worst case I can do a one-way car rental and drive home (6 hours) if I miss the return, but would obviously rather fly (note that I only need the outgoing miles for the status upgrade, so no real harm done if that happens).
That's really all I wanted to know, I guess. I know that FlyerTalk is probably a better venue to discuss this sort of thing, but I am not active over there (yet!). My wife is very dubious about all of this and thinks I am crazy, so I am just trying to allay some concerns. Thanks for any advice you all can offer.
