Sounds pretty cool to me. Roadside removal is a non-issue for me; with the sealant as first line defense and the Airliner as a second, fully rideable line of defense, the need to pull the tire roadside vanishes for me. Maybe self-supported touring would be a situation where the Airliner makes less sense, but for tyical sport riding, it sure sounds cherry to me.

Sy Reene I dunno why you’d not want to run sealant, but yeah, if you’re okay with the diminshed performance of running on the Airliner when flat, you can skip sealant. You could certainly carry sealant and inject it if needed, but the silliness of that should be obvious; if you’re going to stop and faff around with sealant and reinflating, what’s the point of the Airliner? You may as well just do a tube change at that point.
