I once (1,5y ago now) had a combination flight AA + AB.
AB online check-in didnīt work then, though trying to get help as AB gold member via hotline. They didnīt found a way, but maybe nowadays itīs different.
Anyway, as already said: 2h are more than enough and Iīm absolutely sure you wonīt have any hurry.
