Hello all --

I searched the board, but couldn't find a definitive answer on this question. I booked two one way rentals for next week using the A074800 code (CitiFinancial) from Buffalo to Toronto and the A674600 code (unknown origin) for the return trip a week later and got some great rates, however, I'm fearing when I get there they won't honor one or both codes and I'll be stuck in Toronto paying a ridiculous amount to get back. Does anyone have experience with either or both of these codes and whether anyone can use them or if I will need to show some sort of ID? Thanks everyone for your help with this.
