i believe that once the 787's begin to arrive we will see many more international flights. Due to their efficiencies, other star alliance carriers will be sending planes our way. Sadly, usair is ordering the a350 and wont be getting any of those until 2011 at the earliest.
Regarding where we will get, paris and rome are unlikely unless we can support them organically since air france nor alitalia are star alliance partners. thinking of star alliance partners, flights to vienna, warsaw, heathrow, zurich/geneva, portugal, stockholm ar all possibilities once the 787 comes online. the most likely of these is heathrow and secondly i would think switzerland. personally, i believe clt can support a flight, at least in the summertime to paris so those would be the three euro flights i see in the next 3 years
