My friend is travelling LGA-YYZ-YVR. She'll be in Toronto already as she needs to travel there earlier with work and they're paying for her flight.
If she misses the LGA-YYZ segment, can she show up and fly the YYZ-YVR segment still or will WJ cancel the entire reservation?

I've instructed her to call and check but for curious if anyone has had experience with this on WJ.
