Didnt the booking engine always prefer AC flights, and always had a hard time pulling partner options if there were too many AC options?


My annoying issue is that you cant change your FF# on Aeroplan bookings.

We had initially booked and input our UA*G numbers in at booking for free bags. Then tried to change it to the AC# so as E35 could use my eupgrades, website errors out, everytime.
Finally had to call and an agent replaced the number with AC E35 and only then I can apply eupgrades.
