I think I've forgotten a few things. I know I've flown through Seattle, Las Vegas and Atlanta, but not sure when. Probably on one of the California- New York legs... oh well, my memory was better than I though. Sorry for the long post!
Edit: Working on inputting it all into the map.. but I needed to make the list before I did it.
