I ran across this article on another board. It covers a lot of issues concerning US Airways but also touches on their international expansion with the arrival of new aircraft over the next several years.
Vegas Article on US Airways
From the article: "But it will be the eastern hubs - Philadelphia and Charlotte - that will get most of the airline's attention with its European emphasis."
"Andrew Nocella, senior vice president of schedule planning and alliances, said the airline would start out adding more frequency to existing markets before barreling into new destinations. That means more flights to 18 cities that include London, Rome, Paris, Frankfurt and Amsterdam."
I could see them adding several cities to CLT. Maybe not daily service but several frequencies per week to cities like Paris, Manchester, Madrid, Amsterdam, & Rome.
