Just curious, are the taxes/fees greater when booking a First/BusinessFirst SaverPass ticket compared to an Economy saverpass? The route were looking at has EasyPass Economy for 25k miles and SaverPass First for 25k miles.

Also, how far can you go in the system to actually see the final cost associated with booking the reward travel? I selected the flights and it came back at the top saying '50,000 miles + $10', but I 'm fairly certain that's not the final costs associated with the ticket.
