I am a new SE with a question about upgrading. I fly predominantly short flights (YYZ-YQT, YYZ-EWR, YYZ-YUL) and purchase refundable, full-fare (or almosrt full-fare) tickets. My company does not allow purchasing business/executive for short haul flights. Here is my question - Is their a way to upgrade to Business/Executive other than the certificates I get from time-to-time (excluding gate upgrades)? Can you upgrade with points? Can you purchase upgrade certificates. I am also AA Gold and it is easy to upgrade from any fare by purchasing certificates. -
