You can get a jacket with a lot of pockets and then cram all your other clothes into it. Then take the jacket off in the plane.

I'm already a "person of size" at 6'5'' but I never get offered a second seat like that.Be careful, they might class you as a “person of size“ at check in and you have to buy a second seat.

Have you considered using the subway instead?My plan is to fly from Australia to Sweden then from Sweden to Poland. It's cheaper to buy return tickets so I'll fly back from Poland to Sweden then from Sweden back to Australia.
