City Airport TrainorSlovak Lines coach to Bratislava?
The short answer
These do not go to the same place, so price is not the comparison. The City Airport Train reaches Wien Hauptbahnhof and the Ringstrasse beyond it; the Slovak Lines coach to Bratislava does not. Runs east to Bratislava, in Slovakia, not into Vienna. It is here because the airport is fifty minutes from another capital and its own bus page names three operators for the ride and prices none of them.
The City Airport Train is quicker: 21 min against 50 min. The Slovak Lines coach to Bratislava varies between 50 and 60 minutes.
City Airport Train: 06:07–23:37. Slovak Lines coach to Bratislava: 07:30–00:15.

Pay the driver and it is EUR 15.00 flat. Online sales close ten minutes before departure — book on the app before you walk out to platform 04, not at the stand.
The price is a floor. The operator sells this ride at prices that move by date and departure: EUR 7.90 to 9.90 for a departure booked weeks ahead, EUR 8.90 to 13.90 on the day. Its price list's "from EUR 5.90" was on sale for no departure checked.
Two lines, two ends. Line 102806 goes to Most SNP and on to Nivy; line 102807 to the main railway station and on to Nivy. Both reach Nivy; check which end you want before you pick a departure.
Between 00:15 and 07:30 nothing of Slovak Lines' runs, and from 19 September 2026 the 06:30 is gone. RegioJet's first departure is 09:25; FlixBus advertises a 01:25 at a price nobody can state in advance.
Bring a passport or ID card. The operator requires a valid travel document on its international lines, children included, and under-16s may not travel unaccompanied.
