Vienna

• Follow signs to passport control immediately on landing
• Have onward boarding pass and hotel/address ready for questions
• Schengen arrivals walk straight out. Non-Schengen (US, UK, Asia, Middle East) clears passport control at Terminal 3 arrivals, typically 20 to 45 min depending on flight bank.

CAT is fastest at 16 min to Wien Mitte but €14.90 one-way. S-Bahn S7 is the value pick: 25 min to Wien Mitte for €4.30 with a standard VOR ticket, runs every 30 min. ÖBB Railjet only stops at Hauptbahnhof but matches CAT on price via single-fare VOR.

• Leave enough buffer - trains run to a schedule and can be delayed
• Buy your return ticket in advance if possible
• Set an alarm 60 min before your departure gate closes

• Re-entry security at VIE typically takes 10-20 min
• Check your gate - it may have changed while you were out
• Liquids bought in the city cannot pass security - finish or bin them
