I usually fit things in a roller. Just make sure you can safely fold the jacket.
(keep it in a plastic bag with the hanger, and put other clothes between
the folds. make sure the roller is packed and things dont shift that easily.)
If it looks risky, then just carry the jacket with you on the flight.
I've managed to pack things in a single roller for one week business trips
very easily.
