Hello!!!
Potential New joiner here, forgive my ignorance, I'm trying to manage my expectations about the future.

I will not commute, but definitely considering to go once or twice a month from SFO to IAH using any of the 3 flights available between 9:00/13:00, to then catch the IAH-EZE to see my family.

How is this sector (SFO-IAH) normally doing with commuters?
I see that it is operated by 737, 757 and 777 so different options regarding jump seats, but, many commuters on this route that will make my chances to get on board slim?
Are in general commuters going at the mentioned times? or they usually use earlier or later flights?

How about the IAH-EZE sector?
I guess no many staff asking for Jump-seat on that one... Friend told me that captains (in general), will allow you to seat in the flight deck if no seats available.
Any rule on that? Can we use the flight deck in an international flight? Are we allowed to use the bunk (long day starting from SFO?
How about loads in general? Easy flight to get in as standby? or it is like American's MIA-EZE, with 30/40 standbys in each flight.

Last but not least... priority for boarding is by seniority only? or you position plays a role? In my present company, a Captain will always have priority over and FO, an FO over a Cabin Crew and so on, regardless of seniority. How is at United?

Sorry and Thank you everyone.
