I am a CO Silver (thus the moniker), but will make Gold by the end of the year. What does this offer me that as different from Silver? Note that most of my miles are cross-Atlantic. How does it affect these trips? I have been upgraded for my domestic portions in the past (CLE-EWR or on NW CLE-DTW—a whole 25 minutes) Will I get anything international? How about if I fly NW? I know, So Many Questions, but that’s why I ask all you nice people.
