Principal areas of: Fflecsi (stylised fflecsi; Welsh pronunciation: [flɛksi]) is a trial demand-responsive bus service administered by Transport for Wales (TfW) and local authorities, operated by local bus operators across Wales.

During the pilots, fflecsi will replace some pre-existing scheduled bus routes in the service areas where it operates.

[1] The technology behind the service is made by ViaVan, and the pilot is funded by the Welsh Government, to invest in new approaches to public transport in Wales as part of their Llwybr Newydd strategy.

[2] The pilot was included in Welsh Labour's manifesto for the 2021 Senedd election, as part of their plan to increase investment in bus services,[3] and reducing Wales' carbon emissions.

[6] Services in rural areas were shown to increase passenger demand when compared to the previous fixed bus operations.

[10] The following day, a briefing was hosted to introduce the concept to Pembrokeshire, another area where fflecsi aims to operate.

The route is from Tonypandy and Hendreforgan, stopping in destinations in the communities of Penygraig, Williamstown, Penrhiwfer, Tonyrefail and Thomastown.

Fflecsi was rolled out in Denbigh and Prestatyn, in co-operation with Denbighshire County Council and local bus operators.

[18][19][20] In the same month, the final recommendations of the Burns report, chaired by Lord Burns, on behalf of the South East Wales Transport Commission, stated that "[Fflecsi] may be able to augment these [regular] services, especially where time of day or low density of population makes regular services unsustainable".

However, the report recommends that fflecsi be treated as a complement to the existing scheduled bus network rather than a replacement.

[22] On 24 March, Waters further stated: "We are also extending our on-demand fflecsi buses to cover the whole of the Newport City local bus network, showcasing Wales as a world-leader in demand-responsive travel, offering a model for future bus delivery in other parts of Wales.

[25] In September 2021, fflecsi was included in proposals for the North Wales Metro, potentially expanding its presence to new places in the region.

Operated by Prestige Taxis, the area will cover Buckley, Higher Kinnerton, Penyffordd and Hope.

[31] On 12 August 2022, it was announced fflecsi will stop operating in Newport by 25 September 2022, just over a year after the city-wide trial was introduced.

Responding to the trial's performance, Transport for Wales stated that Newport's experience with the service was "successful", had provided "substantial data... to improve future public transport route planning", and gave "useful information" on operating the service in an urban setting.

[39] The services are operating in partnership with Alpine Travel of North Wales and Conwy County Borough Council.

[42] Trips must be pre-booked in advance, and charged £4–£6 for adults, with discounts using MyTravelPass and free services for Welsh concession card holders are available.

Zone 1 replaces routes 1, 1B, 11A and 11C, connecting Rogerstone, Pye Corner, High Cross, Ridgeway and the city centre, while Zone 26 replaces routes 26A and 26C, connecting Old Barn Estate, St Julians, Barnardtown, Beechwood and the city centre.

[53] In August 2022, following the announcing of its terminiation in September, the South Wales Argus reported various concerns their readers had on the service.

Whereas other readers had concerns over potential inefficiency in the service which is taxpayer-subsidised, as well as a case of dropping off a passenger at an incorrect drop-off point.

[56] TfW stated the pilot "was initially funded for nine months and then extended for a further three to obtain more data", that the purpose of the scheme was to provide information to "plan and improve future public transport routes", and that the data had shown a "very high demand on certain urban routes" which would be more effectively served using traditional fixed bus services.

The services are operating in partnership with NAT Group (Adventure Travel; where fflecsi tickets can be used on their other non-fflecsi routes), charged £2 for a single, and £3 for a return trip.

[58] In Rhondda, there is a fflecsi 152 service on the former 152 scheduled bus route, covering Hendreforgan, Tonyrefail and Tonypandy.

The services are operating in partnership with Stagecoach and Rhondda Cynon Taf County Borough Council.

[67] The fflecsi service replaces the bus routes LT1, LT2, and LT3, is charged at £2.50 for adults, £1.50 for children, with concessionary cards providing free travel, and discounts for those with a young person's mytravelpass.

[69] On 27 May 2022, Holywell's service area was announced to be expanded to include Penyffordd, Picton, Gwespyr, Gronant and Gwaenysgor.

The new service only runs on weekdays, and serves an area that includes Aberdaron, Abersoch, Nefyn, Pwllheli, and Trefor, with connections to beaches, camping sites, and other tourist attractions.

[75] Pembrokeshire County Council announced they were able to secure funding for a replacement service provided by Richards Brothers until 31 March 2024.

[74] On 14 March 2022, the service started operating in Ruthin, Denbighshire, with the area spanning the town itself and the surrounding villages of Bontuchel, Clawddnewydd, Clocaenog, Cyffylliog, Derwen, Graigfechan, Llanelidan, Pentrecelyn and Rhydymeudwy.

[7][77][78] The Ruthin fflecsi service was reported to carry more passengers than the pre-existing fixed bus routes did prior to introduction.
