Not really true. They don't have a hard cap like Delta. From Alaska's website, "There can be occasions where extra space cannot be guaranteed due to unforeseen changes such as reaccommodating guests from a previously canceled flight."

Understandable. N95 certainly doesn't hurt. Luckily the only pax you have to worry about are the ones pointed right at you, which is pretty much no one since the middle seat is empty. And since air flows primarily top to bottom, there really isn't a "downwind" to worry about (The front to back portion is very slow).

I see. Yes that's somewhat correct. Only thing is, the ratio can't be changed aside from turning off the recirc fans. Which, as discussed elsewhere, would actually result in less total CFM moving through the cabin (ironically enough) and would require more bleed air to balance out. Bleed air alone results in 100% fresh air, but at a very low CFM rate. Adding the recirc fans dramatically boosts CFM flow while reducing the load on the engines. And since all recirculated air passes through a HEPA filter, the overall safety is increased due to the increased speed of the air being replaced in the cabin. On average the entire volume of the cabin is replaced every two minutes with everything running normally.

I knew it wasn't directed at me. I was making fun of you for being a tool (your "pissant" comment). Missed approach.

a) incorrect. They're using the same procedures as always for airflow. b) 100% of the recycled air goes through the HEPA. SARS doesn't float around like dust. It's attached to droplets that fall. So the only way you're getting infected on a plane is someone close to you coughs/sneezes/breathes in your direction. So yes, if the person two seats over turns to you and sneezes, and for some reason REMOVED their mask, then you would need an N95.

Doesn't change the fact you're wrong. Air moves top to bottom and front to back whether the recirc fans are on or off. Turning them off just slows down the airflow. Not a single fleet at Delta turns off the recirc fans. It's better to leave them on and keep the air moving through the HEPA filters. Fresh air still enters the cabin from the packs. Recirc fans simply help the packs move more air.

You don't know what you're talking about. Recirc fans help the packs cycle air through the HEPA filters. Air moves from top to bottom and front to back.

If you're 6'2" or less, economy is pretty comfortable on Delta. Especially now with the middle open. 6'3" and you really need C+ or First.

Pissant? Pissant!? Pissant.

Your friend wasn't on Delta then. They have a hard cap and won't go above it for any reason.
