Please be aware that the T9 bus is an express service to Cardiff Airport, which means that passengers cannot be dropped of at bus stops along the route towards the airport.
You may notice the journey planner offers you a route from Cardiff to the airport on the T9, then suggest you catch the next T9 service back to your stop.
This is a valid journey plan, with the journey being a similar length of time as other route options. However, please be aware this could be a more expensive option, as it will require you buying two single T9 tickets.
If you are unsure or wish for more information, please give us a ring on 0800 464 0000.
