United had a "program" in the pre-FF days where you got a wall plaque, and when you flew to or through different cities, they would send you a metal strip with that cities name engraved. When you flew to (thru) a city either 5 or 10 times, or more, you got a silver, and then a gold metal strip. As was said before, when the FF programs began, you started off with 0 miles, even though you had city strips up the gazoo! So be it.
As they say, rules is rules.
