The boarding process took FOREVER. I arrived three hours before my flight and barely made it to the gate in time for boarding and there was no waiting as all to pass through the security checkpoint. Emirates simply was understaffed on Jan 7th 2022. More importantly, the flight crew made very little effort to enforce the mask requirement and the result was everywhere you look you could see passengers with their mask not covering their nose, and then after seating many didn't have the mask covering their mouth either. It was a total health hazard. Unacceptable.
