My wife and I were originally on one reservation. At some point we appear to have been split (not at my request) -- we got boarding passes on Mar 2 with two different confirmation numbers. Now trying to check in for a flight on Mar 6 and she is gone -- my MileagePlus account shows my information, and hers shows mine too. Neither shows hers.

Now at 2 hours on the premier line trying to get her reservation back. Why is this taking so long?
