I only use ZEDs when I travel outside North America with my wife. I never use domestic airlines for that travel, the foreign airlines always seem to have better seat availability and their Economy or Economy Plus style seating is better than domestic. I traveled 18hrs in United Economy once, and ouch!

I obviously like to have more options but for now we have plenty of selection from foreign carriers. The pass bureau said they’re close to getting United back because they like the routes we now serve.
