Standard GO service is approaching good enough that the issue of non-airport users crowding the UP trains is being resolved.
My impression from riding UP is that both of the current midway stations do generate a solid volume of ridership to the airport, so stopping there is good business. I would predict that both Mount Dennis/Line 5 and Liberty will do likewise.
As nice as an all express ride sounds, I’m not sure that having a few stops really matters. Passengers to Union get a fast, frequent, and more pleasant and reliable ride than a limo, and UP equipment and stations are at the upper end of rider experience and convenience. Deriving ridership and revenue from those intermediate stops likely outweighs the number of potential customers who would not use a stopping service. We do not have to duplicate Heathrow Express to have an airport service that gets good ratings and reputation, and moves people well..
I am more concerned about bus and LRT and subway connections - having taken transit to the airport in many cities, I find that “regular” transit may connect to the airport well, but can be more challenging - there is seldom good accommodation of luggage.
Certainly there is an upper limit to how many stops one can tolerate… take the Tube from Heathrow to central London, or the Orange Line from Midway to the Loop, or RER from CdG to central Paris, and things do get more tedious and much less relaxing. The environment is less secure, less pleasant, and more crowded.
UP is a case where good may be good enough.
