Airport limousine buses serve major districts and hotels directly, costing a bit more than the subway but offering comfortable, traffic-dependent rides. Taxis and ride‑share provide door‑to‑door convenience at a significantly higher cost, while driving yourself means paying for airport parking in short‑ or long‑term lots.
