I'm considering booking a trip from CLT to BRU. My choices are pretty limited; it seems like they are: 1. CLT - PHL - BRU all on US metal. 2. CLT - LHR on US, LHR - BRU on BA metal (six daily). I haven't decided if I will use miles for all, part, or none of the journey whichever routing I pursue. When I hit usair.com and enter the departure / destination combination I don't see the LHR - BRU as an option. I'd like to get over the pond on the first leg if possible. In the past I'd used Lufthansa to get to Europe knowing I'd rather be stuck there than in Philly (Phillytude and all). I've got a ton of miles on pretty much every program via US, AMEX, UR but I also need some PQM's so I'd consider buying a coach ticket and using miles for an upgrade. Is there some other way to see these types of routes and book them?
