Take the S8, not the S9. Both leave the same platforms westbound, but the S9 turns off after Mainz-Bischofsheim to "Mainz-Kastel" — a district of Wiesbaden on the far bank of the Rhine, by RMV's own tariff plan — and never reaches Mainz Hauptbahnhof.

Four or more of you: buy the Gruppentageskarte at price level 4, EUR 22.50 for up to five, against EUR 6.90 each. Three pay EUR 20.70 in singles and lose EUR 1.80 by taking it — unless they are coming back the same day.

Every one of the 141 westbound S8 departures in RMV's 2026 timetable takes 29 minutes to Mainz Hauptbahnhof, at :00 and :30 past the hour, day and night.

On Sunday-to-Thursday nights, service to Mainz thins: the 02:00 and 03:00 trains end at Kelsterbach and the 04:00 slot is an S9 to Wiesbaden, so departures are hourly between 01:30 and 04:30 (01:30, 02:30, 03:30, 04:30). Friday, Saturday and pre-holiday nights keep the half-hourly S8 service. Night departures may be replaced by buses.

Until 19 September 2026, the S8 is replaced by buses between Mainz-Bischofsheim and Rüsselsheim from Friday 11 September 21:00 to Monday 14 September 05:00, with further night closures (21:00–05:00) until 25 September. Nothing has been published for after 25 September.

Going back, a Mainz city ticket (EUR 3.90, the Wiesbaden/Mainz level) is not valid to the airport; you need Preisstufe 4 again.

Nothing waives the EUR 3.80 surcharge except a first-class Rail&Fly ticket, the Seniorenticket Hessen Komfort, or companions of disabled passengers. An RMV single, Gruppentageskarte, Deutschlandticket or Rail&Fly with RMV validity still pays it; a Deutsche Bahn ticket needs the RMV fare too.

No cash on board. Buy cashless from the driver, in advance on the HEAG mobilo app, or — for the surcharge alone — by contactless card, phone or watch at the validator by the second door; keep the card you paid with for the inspector, since there is no paper ticket. The airport's RMV machines do not sell this surcharge.

Terminal 1 only. From Terminals 2 and 3 take the free SkyLine to Terminal 1 first; the operator says so in terms.

The half-hourly pattern breaks in the evening: after the 19:17 the next is 20:02, and the last is 00:02. Between 00:02 and 04:47 nothing goes to Darmstadt from this airport, on this bus or the X15.

RMV's express bus X15 does the same relation for EUR 6.90 without the surcharge — an hour longer, hourly, and to Mathildenplatz rather than the Hauptbahnhof.
