When people are sitting right next to you , it is hard not to breathe some of their exhalations before they get sucked out and filtered.

Which is also true in the local market — multiply by number of people in the store, where the air is neither flushed nor HEPA filtered. The person in the seat next to you is exhaling through a mask. Also, there’s airflow between your seats — and much more if you turn up the little air nozzle at your seat.

Which is why the air you breathe on an airplane is safer than the stuff you breathe indoors on the ground.
