Travellers faced delays of up to 17 hours between Friday (31 March) and Sunday (2 April), which was put down to slow processing and an unexpected number of coaches.
First reported on Friday, the disruption became so serious over Saturday and Sunday that several coach companies turned around and returned home because of “critical” delays.
According to the Confederation of Passenger Transport (CPT), coaches were held back behind cars and HGVs, resulting in queues of between eight and 24 hours.
