Technically speaking the flight x-YYZ would be considered "out of sequence". But you can get around this by cancelling the first segment and ripping out the 1st flight coupon. They they won't notice.
Now I have a question for you Avionics Boy: I went on a CP 320 again, those J class reading lights (attached to the seats) are in serious disrepair. We were in seats 2A and 2C, and neither of the lights worked, and on of them was out of socket and hanging from a wire. Any idea why they are not being maintained?
