Tried 16 Plus (similar dimensions to an Air) in an Apple Store today, naturally without a case and it was doable, kind of right on the border for me. A 16 without a case was comfortable. Hmmm, what to do . . .For myself, regular 16/17 phone size almost reached the limit of use it with one hand. Air's larger and wider display might be too big.
Better to try by yourself in store.
