Here's the deal. I am a US Airways Divident Miles account holder. In the past few years I've been able to reach the "Silver" level consistently, but this year I'll be a bit short of the mark. I stated with US Air because they flew out of Colorado Springs and had a wide variety of destinations (thru Phoenix). US Air, however, doesn't fly out of the Springs any more, so it's not my primary airline of choice anymore. Now I travel United Airlines more often. Here's the question: since I'll be losing my sivler status anyway, is it worth it for me to start a new frequent flier program with United? Both (US Air and United) are in the same "Star Alliance" network. I still have about 18K miles w/ US Air.
