I fly out of YYZ and my work requires me to make 4 to 5 long-haul round trips per year from Canada, mainly to India, the Middle East and Africa. Once I am in those regions, I often do multiple regional flights as well from city to city and while I always try and fly Star Alliance partners in those regions, I also find myself frequently on Jet Airways flights (in India) and Emirates flights (within the Middle East). I just hit e50K/Star Alliance Gold for 2019.

I am considering requesting a status match and shifting loyalty to a different carrier that a) has a better Economy product than Air Canada b) Has a much better prospect for upgrades as Air Canada's program is awfully restrictive in upgrading economy passengers and c) provides good coverage in their route network for the regions I travel to - right now, the smart option looks like Turkish but open to all of your advice please, thanks!
