Very new at using points and miles so any advice will be much appreciated. Just used up a lifetimes wort of accumulated Aeroplan to book a mini RTW business class trip for wife and myself from Toronto to Goa, India and back in March 2020. Going via Europe with Stropover in Istanbul and several long layovers returning with a Stopover in Singapore. Got confirmed bookings all sectors except EVA TPE-ORD on BR 56 on 3rd April 202 is Economy. I am monitoring Aeroplan for BC availability on EVA but somehow they do not seem to have released any BC seats for that period on any of their flights. Any suggestions on how I can monitor and upgrade this one sector when BC seats are available? Even one seat upgrade will be appreciated since it s 15 hour flight and I have already paid the points for BC all the way.
