A320 domestically, B787 overseas.

It's an Osprey Aether 85. If I remember, it has a somewhat of a stiff backboard. I guess the reason I wanna bring it is to bring lots of goodies home (will use a 30" luggage for my clothing and etc)

May have to stick to my Arcteryx Axios 50 which I had no issues before.

Or wonder if I can stick my 50 into the 85 after the 85 gets out of the carousel during the beginning of my trip? that way I can carry the 85 with the 50 in it and still have a free hand I will have to try it at home next few days.
