No matter the size of the bassinet, we could not have used one with my son at 8 months - he was already pulling himself up to a stand by then (walking at 9 months) and there is no way we could have actually kept him in the bassinet when he was awake. He started flying at 4 month, and was an experienced traveler by a year - we always used his 5 point restraint carseat, which kept him fairly happy and safe, and took a lot of stress off of us.

He also hated small, confined spaces and would have howled over that aspect of the bassinet, too. He didn't mind being in the carseat because he had a good vew from it. To this day he always dibs the window seat for the view.
