Pros: Absolutely nothing!
Cons: Aeroflot's employees in FCO airport are bad and cruel people. My wife was denied access on our flight home because they wouldn't accept the United States Embassy's boarding foil a permanent resident who had her green card stolen. The Aeroflot supervisor accused us of fraud and forgery saying that the letter was a fake that we created. We pleased with her to call the number on the letter so that she may speak to embassy directly and she said she wouldn't do so. She kept saying we made the letter ourselves. I asked to speak to her manager or someone above her but she wouldn't direct me to anyone. She said that it was too late to let us go through the gate anyway even though it was 2 hours before the flight was to take it off. I went through the gate since I'm a US citizen and tried to speak to the supervisor at the boarding gate but it was to no avail. Even though I had the embassy duty officer on the phone, the supervisor refused to speak to her and kept pointing at my letter and saying "fake, this is fake." This whole ordeal completely ruined my wife and my honeymoon not to mention, cost me nearly $2000 in lodging, food, and two last minute new flights to the United States with US Airways. I would really like someone to reply to me regarding this issue.
