That is an interesting question, to which I have already given a lot of thought.

I would fly with the airline who took over the SkyMiles frequent flier program and incorporated it into its own frequent flier program, such as Delta Air Lines did with Pan Am World Airways, or Continental Airlines did with Eastern Air Lines (although they already shared the OnePass frequent flier program), or American Airlines did with Reno Air and Trans World Airways.

If that did not happen, I would fly with the airline(s) that accepted SkyMiles as currency — hopefully, with as little devaluation as possible — such as with a SkyTeam partner or Delta Air Lines partner.

Assuming that neither scenario is possible and SkyMiles instantly became absolutely worthless where I would have to start all over again, I would abandon the SkyTeam alliance altogether.

I am currently a Silver Elite Dividend Miles member on US Airways, and I have enough Dividend Miles for award travel. That would take care of Star Alliance for me.

However, I also have American Airlines AAdvantage miles as a result of American Airlines, Reno Air and Trans World Airlines, but I have no status in the AAdvantage frequent flier program.

However, I would have to depart from the D gates in Atlanta when flying on US Airways, whereas I can depart out of the T gates in Atlanta when flying on American Airlines. American Airlines gets the nod here. On the other hand, I can use United Airlines out of the T gates and earn Dividend Miles, but then I would not eligible for Elite privileges on United Airlines, and I really do not want to keep track of another frequent flier program such as Mileage Plus.

I have to choose between connecting through Charlotte, Philadelphia, Phoenix, Pittsburgh and Las Vegas on US Airways (or Chicago, Washington, D.C. (Dulles), Denver, San Francisco and Los Angeles on United Airlines), versus Miami, Chicago, St. Louis and Dallas on American Airlines. The jury is still out on this one, as I have not completely analyzed what is best for me.

Then again, I would consider switching to an airline that uses Atlanta as a hub for convenience purposes. AirTran is not out of the question, and I do belong to their A+ Rewards frequent flier program.

I also am giving equal weight to just abandoning this whole frequent flier nonsense and select my flights based on overall value, including price, convenience, comfort, schedule, service, and the opportunity to earn miles and points.

In other words, I have no idea. I will decide if the time comes, but for now, I will remain with Delta Air Lines.
