Quick answer: The Aerobus (~€8, every 5–10 minutes, ~35 minutes to Plaça de Catalunya) is the simplest from either terminal. The R2 Nord train (~€5) is the cheapest from T2, and the L9 Sud metro (~€5.50 airport ticket) serves the wider network: a taxi runs €35–40.

| Option | Time | Cost |
|---|---|---|
| Aerobus (to Pl. Catalunya) | ~35 min | ~€8 |
| R2 Nord train (from T2) | ~25 min | ~€5 |

| Taxi | 25–35 min | €35–40 |
Taking the Aerobus, step by step
Follow the bus icons outside arrivals at T1 or T2 (separate A1/A2 lines: board the one for your terminal on return), pay contactless on board or buy online, and ride non-stop to Plaça de Catalunya with a couple of central stops. Departures every 5–10 minutes, roughly 5am to half past midnight.
Arriving at night
After the Aerobus stops, the N17 (from T1) and N16/N18 night buses cover the route cheaply all night, and taxis queue at both terminals around the clock with a modest airport supplement. The trains and metro sleep: plan on bus or taxi for red-eyes.
Tips & common mistakes
The R2 train leaves from Terminal 2 ONLY: from T1 take the free green shuttle first: with luggage that transfer can erase the savings. The L9 metro needs a special airport ticket: your T-casual pass is not valid for airport stations. Beware unofficial drivers in arrivals: licensed black-and-yellow taxis queue outside.
Which Option to Actually Pick, by Traveller Type
The comparison table lists the routes; the harder question is which one fits your specific arrival. Match it to your group and luggage rather than to the headline price. Solo or a pair travelling light and landing at Terminal 1: the Aerobus, around EUR 7.25 and roughly 35 minutes nonstop to Placa Catalunya, is the least-thinking option, with four dedicated luggage holds and departures every few minutes. If you land at Terminal 2, the Rodalies R2 train is faster and cheaper at about EUR 4.60 in under 30 minutes, but only because the station sits at T2; from T1 the free inter-terminal shuttle plus the wait usually cancels out the saving.
Three or more people with bags: price the taxi before defaulting to the bus. A flat metered ride of roughly EUR 35 to 40 split three ways often beats buying multiple Aerobus fares and gets you to the hotel door instead of a square. Families with a stroller and a tired child almost always come out ahead in a taxi for the same reason.
Two mistakes catch first-timers repeatedly. The T-Casual multi-ride pass is not valid at the L9 Sud metro airport stations, so people get stuck at the gates and pay again. And the L9 Sud metro does not run into the centre at all; it ends at Zona Universitaria and needs a transfer, so do not board it expecting a one-seat ride downtown.
- Flying out later: the round-trip Aerobus ticket (about EUR 12.50, valid 15 days) saves sorting transport again on departure day
