Ground Services question

Are jetways standard for default ground services? I’m looking at ‘hiring’ out ground services to save a few bucks but do not want to risk pax happiness if they get jetways with the default. I see a lot of options to sub out, but any that have capacity left also offer no jetways. I assume this factors into pax satisfaction and ratings.

Default is 3 stars with no jetways, AFAIK.

3 stars is correct, but the jetways are linked to real life jetways or not.

Would a 4-star terminal with NO jetways be better or worse than 3-star one WITH jetways?

3 stars is correct, but the jetways are linked to real life jetways or not.

thanks for the info!
