I have flown on those Embrae (sp) and unless there is something I have not seen among those ac, they are puddle jumpers and there is no first class..they are cramped little miserable planes with one seat on one aisle and 2 seats across the aisle. My bet is they were on a connecting flt on the way to say Seattle to catch a big bird home.
You’re right, real airplanes don’t land at Vancouver.
