AC Flight Numbers...?
This...is probably an ignorant and stupid question, but I am booked YVR-YYZ next year (en route to TLV ^ ), and I noticed the flight number is AC1166....my question: why the four digit number? Aren't YVR<->YYZ flights normally like 13x or 14x or something like that?
What do the four numbers mean, if anything at all?
