I am jumpseating. I have been told in the past that I must list prior to showing up. But that makes sense to list at the gate since listing omc can only be done at the gate.
I am going to find out tomorrow how it goes not listing.

Another question, how do you list when out of the country? Since riding up front isn't allowed? I've been stuck in cabo because of not having a
"ticket number" and them not being able
to list an omc.
