Weird!! I was able to get a really cheap one-way ticket with AC from MIA to YVR (YVR to MIA was twice the price!!) and a reasonably cheap one-way from YVR to MIA, using a couple of $100 UA coupons I've been holding for some time.

Bottom line - return trips for wifie and self for about $500 each round-trip all-in, and the possibility of upgrades for the return portion on AC. This puts wifie back to E and myself back to SE.

Thanks, all, for the invaluable advice you've provided on this thread
