Weighing up a job in Zürich while keeping our flat in Aarau, and I want to sanity-check the commute maths before signing anything. Door to door I estimate 70 minutes each way: 12 minutes walk, 33 minutes on the fast train, then a tram. On cost, a GA is CHF 3,995 second class against roughly CHF 2,700 for the Aarau–Zürich route abo plus Halbtax, so the GA only wins if I travel a lot at weekends. Questions for people doing this daily: do you get a seat at 07:10, how often does the connection actually fail, and does the employer contribute anything toward the abo?
