Exposure rate.

Cabins including a max of ten rows each would reduce exposure and reduce occupancy limits by 15%.

Cabins including a max of five rows each would reduce exposure more and reduce occupancy limits by 30%.

Cabins of varying sizes designed to hold families or groups traveling together, not sharing a cabin with anyone outside of their party, would reduce occupancy limits by 50% or more.

Individual closed off cabins, with individual HEPA air filters, which captures most, but not all pathogens (EPA, 2019).
