So I have been noticing at various airports, including Manila, Cairo, and a few others that sometimes if I call for either boarding or deplaning the baggage carts don't come to the airplane. I see them but they are completely missing the tug that pulls the carts and thus the plane doesn't load. It has happened with the default being 737 and airbus a321. I have also noticed it with the wilco pub 737 and level-d 767.
I usually reset the position multiple times before it shows up. I don't have specific gate information for airports right now but I am sure the next time it happens I will let you know. It is a little weird that everything works except the tug pulling the baggage carts is missing. Any ideas?
