Hi You all, I am looking for some opinions from many of you who are so knoledeable about miles etc. i fly about 2-3 times a month for business and being self-employed look at the fares to the most important factor. being in Wash. DC area and with 3 airports (DCA<IAD<BWI) there are all kind of fares available. I am wondering would you pay a lot more fare and stick with 1 airline or save on fares and have silver status with 2-3 airlines rather than platinum with one. Just thought may be i can make better decisions with input from you all. thanks so much.
