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.

From

The bus station in front of Terminal 1; the bus then serves the airport's own site gates — Tor 3, the Lufthansa base, Tor 23 to Tor 31 — before leaving the grounds

To

Darmstadt Mathildenplatz in 63 to 68 minutes, via Walldorf, Mörfelden, Gräfenhausen, Otto-Röhm-Straße and Willy-Brandt-Platz; it does not call at Darmstadt Hauptbahnhof or Luisenplatz

Luggage

An ordinary RMV express bus, not a coach; no published luggage rule.

Runs

05:16–00:16

Journey

63–68 min

Twice the AirLiner's journey time, once an hour, ending at Mathildenplatz rather than the Hauptbahnhof. It is EUR 3.80 a head cheaper — EUR 19.00 cheaper for five with a group ticket — and the only Darmstadt bus with no surcharge on a plain RMV ticket.

The first 15 minutes are spent on the airport's own grounds: the timetable puts Tor 31 fifteen minutes out and Walldorf Okrifteler Straße twenty.

Last bus 00:16, first 05:16, every day; nothing to Darmstadt from this airport in between.

The fare level is RMV's matrix figure for the relation, which RMV says is "for the shortest possible connection"; the X15's own fare level is not published elsewhere. Buy the ticket to Darmstadt, not to an intermediate town.
