Hawarden services :
These started in April 1962 when Starways, based at Speke, made a stop on one of their daily Liverpool-Heathrow flights, initially with DC-4s, later with Viscounts. British Eagle took Starways over in January 1964 (gaining their Liverpool base) and continued the once-daily stop. Cambrian had also built up a Liverpool base with routes transferred from BEA, and were operating a once-daily schedule to Heathrow, although this was basically an intermediate stop on an Isle of Man to Heathrow services, Eagle providing the main service which had built up to about 8 daily rotations by 1966, some with Britannias and later One-Elevens, although the Hawarden stopper was always a Viscount.
Eagle went out of business at the end of 1968 and Cambrian became the main Liverpool operator, expanding the Heathrow route from one to five daily round trips, but Hawarden was never served. They applied to the ATLB for a licence for it, but this was never followed through.
There are still daily services out of Hawarden but they are private charters for BAe/Airbus to Filton and Toulouse, currently using a chartered 146 I believe.
In the 1960s we lived in Hoylake in the Wirral and a friend's father sometimes used the service from Hawarden, saying it was easier than getting over to Speke.
The Welsh Assembly has recently made funds available for a "North Wales to Cardiff" air service, which is going to operate to Valley in Anglesey. This is way off the populated areas of the country and looks unlikely to succeed. Hawarden would have been a much more effective point, it's in Wales (just !) which will satisfy the political point, has good road links with the North Wales coast main towns, and is close to the largest town in North Wales, Wrexham, which surely would deserve to be served first.
