I didn't mean to snap at an 'Old-Timer' around since the days of Randy, so my apologies (you can't see details on the stupid mobile version)!

I guess if I were you, I would start looking for an outbound flight once those seats become available for booking on whatever routing UA and its partners will allow. Obviously the transatlantic portion is the most important to nail down, so look for those flights if you can't get something close to home, and bolt on a connector as appropriate. You can then build the returns accordingly.

Good luck!
