Our flight was at4:45pm, and they allowed us to check in at 9am, which is good that we don’t have to carry the luggage to walk around. Our seats were assigned at the very back, and we requested to have it closed to the front, they were able to move forward a little bit. We requested to ship our carry on, but they charged extra fees, other airlines like air Canada would encourage customers to ship their carry on.
