| Private car service | Emailed quote based on airport, terminal, vehicle class, pickup point, wait policy, route corridor, and timing | Confirmed vehicle class, luggage fit, the IAH-or-Hobby decision worked out in advance, Medical Center entrance precision, cruise runs, and group movement | Higher cost floor than shuttles, taxis, or basic ride-app dispatch |
|---|
| Taxi | Metered pricing plus published airport departure-fee and late-night surcharges, route, and traffic | Simple trips from the taxi stands outside baggage claim at either airport when vehicle class and emailed terms do not matter | No pre-confirmed vehicle class, luggage-fit planning, or assistant-managed itinerary |
|---|
| Ride app | Dynamic app pricing with airport pickup-zone and wait variables | Flexible travelers comfortable with designated app pickup doors at IAH and the Curb Zone pattern at Hobby, and with changing instructions | Final vehicle fit, pickup point, price, and wait experience can vary with demand, especially during rodeo, stadium-event, cruise-morning, and storm windows |
|---|
| Shared-ride shuttle | Per-seat shuttle pricing with multi-stop routing | Solo budget travelers without tight schedules who accept shared vehicles and multiple drop-offs | Multi-stop routing stretches the 22-mile IAH corridor, and there is no vehicle-class control, luggage planning, or emailed terms |
|---|
| Rental car or self-drive | Rental, fuel, toll, airport parking, and hotel or port parking costs | Travelers who need a car for several days across the metro's loops and spokes | Usually inefficient for a one-way airport transfer, and the driver absorbs loop routing, flood-aware rerouting, and event-traffic decisions alone |
