It is a great place to wait when departing, wide varity of food options. Is along two large road systems, so easy to access. Terminals are spread east to west so very easy to access with out any crowding. ....but ONT is two story high to board. Ontarion also has no major city hub, so that helps in traffic and crowding.. But is a poor place for car rental as have to travel to rentals areas. fast tsa
I am comparing this airport to PDX, PHX, LAS Vegas, and Orange county. Orange county was easy to access and has a fun waiting area and fastest tsa. When waiting to board ground at orange, their are folks to help you board taxi. ONT has fast TSA Phx is downtown and very crowded and its gate waiting areas are really strange, but easy to access ground transport than PDX. Vegas is also easy rental acccess and ground. PDX, my home airport, is easy to acces because there is nothing to the north of the airport, but has very long walkways to terminals. PDX TSA is poor. PDX gets top ratings because it is modern and the gates are spread out very far, so very quiet waiting when comparing it to other airports. as in ontarito, while PHX the gates are bunched up and very loud and uncomfortable. while ONT has glass walls for gates and spread out.
