1. Train + Shuttle Bus: The Integrated Rail Link
Since August 2023, Transport for Wales and Adventure Travel have offered a seamless integrated ticket combining rail to Rhoose station and the 905 shuttle bus to the airport terminal. Trains depart hourly from Cardiff Central to Rhoose Cardiff International Airport station in 34 minutes, then the 905 bus completes the 8-minute journey to the terminal. Total cost is £7.20 for adults, with season tickets available for regular commuters. This is the most budget-friendly reliable option for solo travelers without heavy luggage.
Timetables align precisely: the 905 shuttle departs Rhoose station within 5 minutes of most train arrivals. Children aged 5-15 pay £2.60, and concession fares apply. The service runs seven days a week, though Sunday frequencies drop to every two hours.
2. Direct Bus X91 (Airbus): The Most Frequent Service
The X91 Airbus, operated by First South & West Wales, is the most frequent direct bus to Cardiff Airport, running every 15-20 minutes Monday-Friday from 05:20 to 23:35. On Saturdays, it operates from 07:10 to 00:12, and Sundays see combined X5/X91 service from 08:15 to 22:15. The fare is £3 single or £5 return, with journey time averaging 30 minutes from Cardiff Central Bus Station.
Unlike other routes, the X91 stops directly outside the departures hall, eliminating the need to transfer. This makes it ideal for early-morning flights or travelers with moderate luggage. Real-time tracking is available via the Traveline Cymru app, which shows 95% on-time performance during 2024-2025.
3. Other Bus Services: Budget Alternatives
Bus 304, also operated by First, runs hourly Monday-Saturday via Barry and Llantwit Major, taking approximately 58 minutes to reach Cardiff City Centre. The single fare is £2.65, making it the cheapest direct bus option. It stops at Cardiff Bay and Customhouse Street, serving travelers from south Cardiff.
On Sundays only, Service X5 (First) operates every two hours with a 40-minute journey time and £2.85 single fare. Service X45 by Shamrock runs hourly Monday-Saturday during the day, taking 35 minutes at £2.75. These are less frequent but useful for budget-conscious travelers with flexible schedules.
4. Taxi: The Premium Convenience Option
Checker Cars is the official taxi operator for Cardiff Airport, with ranks located outside the arrivals hall to the right. Fares are fixed: approximately £30 to central Cardiff, £45 to Newport, and £65 to Swansea. Taxis are available 24/7 and can be pre-booked by calling 01446 711 747.
For large groups (4+ passengers) or travelers with mobility needs, taxis offer door-to-door service in just 20 minutes from Cardiff Central. Veezu and other platforms also offer app-based booking with estimated fares starting at £27. Night flights often see higher demand, so pre-booking is recommended after 22:00.
5. National Express and Long-Distance Coaches
National Express operates direct coach services from Cardiff Airport to Cardiff Coach Station and major UK cities including London, Birmingham, and Bristol. Services are less frequent (2-4 daily), with journey times from 75 minutes to Cardiff Central and fares ranging £5-12. Booking in advance via gobycoach.com yields the best rates.
This option is best for inter-city travelers arriving by coach rather than those starting in Cardiff city centre. The coach stop is conveniently located in front of the terminal building.

Final Recommendation: What's Actually Best?
For most travelers, the X91 Airbus is the best overall option: it is direct, frequent, affordable (£3), and takes only 30 minutes. For budget solo travelers with flexible timing, the integrated train+shuttle at £7.20 offers proven reliability. Families or those with heavy luggage should consider taxis at £30 for door-to-door convenience. Avoid relying solely on buses 304/X5 for time-sensitive flights due to hourly frequencies.
As of May 2026, Cardiff Airport continues to invest in public transport integration, with new接触less payment systems rolling out on the 905 shuttle by late 2026. For live updates, always check Traveline Cymru 24 hours before departure to confirm timetables, especially on Sundays and bank holidays.
