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.
