I've also have never had trouble getting retoractive credit for miles on Air Canada ever. Also, like BlondeBomber, I've gotten more than I deserve on several occasions (most notably flying only one-way on a return ticket - I still get miles for the return segment - defies logic)

Got back from LHR yesterday and AC was great. I got upgraded going, my flight back was originally connecting through Ottawa to Toronto - they endorsed the ticket to a non-stop flight to Toronto (no charge), and I got triple miles for the trip.

Sorry about your trouble Baobob - I still think Aeroplan is an excellent ff program (Business class rewards within North America for only 30K miles rather than 40K eveyone els) Today's Globe and Mail (Canada's business newspaper) stated that Canadian Airlines is having trouble attracting frequent fliers as ff's mostly prefer Air Canada (Admittedly this is only a comparison of Canada's two airlines - I realize that you may make a "lesser of two evils argument")

(w.r.t. your profile)
Hopefully your H1 should come thru soon - the new quota begins Oct. 1
