Wine - please feel free to move this to a better tread - but I couldn't easily find it in the search as I am sure this has been discussed....

my friend, not a major traveler and rarely been thru SFO, has an upcoming DEN-SFO-Hawaii flight
the connection time is about 30minutes in SFO
- tickets book on UA app

I know they bake in some extra time on these flights, but just seems a little tight - but UA allowed it
(she will have luggage)
