Avianca is listed on the pull down menu but entering the data does not work. Error message indicates that flight number is not correct (and it clearly is correct)
Called aeroplan. Agent very pleasant but could do nothing but put note in file and advised to send in info. Did that two weeks ago and suspect I will be waiting for a while yet.
Second flight (and I entered aeroplan numbers myself on this one - relied on Air Canada the first time) now 2 weeks ago with no miles yet credited.

Flights were booked with Air Canada.

Presume Avianca hopes that I will give up.
Should get hassle miles in addition to those due.
