Upgrading an Award Ticket Booked via Aeroplan
Apologies in advance if there's a thread this belongs to, but searching didn't turn up anything too relevant.
I booked LAX-HKG via an AirCanada Aeroplan redemption (eco, X fare), but would like to possibly pay for an upgrade to Premium Plus or Polaris.
The United site and online chat can't do this... are there any good options? Unfortunately I don't have enough UA miles for two of us, otherwise I'd probably have done that...
