As CO announced their joining Star Alliance in 2009, I wonder if CLE-CDG will survive and your ticket going to Rome maybe see some re-routing if CO does join in Star Alliance before your trip in May 2009. Air France is almost for sure to kick CO out from Terminal 2 at CDG and CLE might see flights to FRA rather. I wouldn't imagine that Skyteam will be too nice to CO from 2009 onwards. I may be wrong.
