🚇 Airport → city center

Almost always — yes. European airport buses (Roissybus in Paris, Aerobús in Barcelona) cost $5-16, and Prague's bus 119 + metro is just $2. The exception is London Heathrow, where the Underground is cheaper than any bus.

For metro and commuter trains, buy on arrival — prices are identical. For airport express services (Heathrow Express, Vienna CAT), booking online is typically 10-20% cheaper.

No. Dubai uses Careem, Tel Aviv uses Gett, Turkey uses BiTaksi or Uber, most of Europe uses Bolt or Free Now. Doha relies on the Karwa app or the metro.

Between 23:00 and 05:00 first check if a night bus runs (Noctilien in Paris, Night Tube in London on weekends); otherwise Bolt or Uber is the safe pick — slightly pricier but no queue and no language barrier.

At CDG and FCO fixed-tariff fares are mandatory — you can't be overcharged. Dubai's RTA Taxi (silver bonnet) is official. In Istanbul, hail a yellow cab via the BiTaksi app — that locks the fare in.
