Got it schmoops and Mr Tickets, 'appreciate it!
Twitter rep quickly linked mrs ti22 to my Nov 11 outbound flight and confirmed desired EC seats together. Myself in middle just in case my UG goes through 'will at least have her window EC, LOL.....
Then bought-up her outbound solo EC even though I probably could've gamed that with some "creative" award booking/redeposit kung fu. No real need for that potential mess and hassle though....
Thanks to all for good, solid, helpful advice!
