CLT
Not only silver but on my way to gold on 15 May! 2 Transcontinental r/t's and the 1 transatlantic helps. Got SEA-BOS coming up in two weeks through the not-very-direct route of SEA-PIT-DCA-BOS-LGA-PIT-SEA! Pity I have to go out of my way to fly US.
How fast does US send out the preferred materials and upgrades? These are going to Canada.
