Hi Nigel, I have been over and back to Ireland regularly the last few months, mainly Donegal, but have also been into Weston three times, twice in the C340 and once in the Arrow.
The expense of DUB itself made Weston my first choice with DUB the alternate in case the cloud base dropped below the 1500 feet you need for the VFR routing from the Pigeon house chimneys at the entrance to the River Liffey route through the city.
I came across on a Y flight plan (IFR to VFR) with the switch planned around the Killiney NDB KLY which sets you up for the VFR route to EIWT. However, in each case as I descended down from FL160 as soon as I broke cloud and could make out the chimneys they allowed me direct to there, for an enjoyable low level flight down the Liffey to the Palmerston Roundabout, where DUB tower hands you over to Weston to slot into circuit or more likely clear you for a final to RW25.
Weston has now changed hands back to people who want to make it an airport again! Last Sept, you could only fly in on certain days, when they were not filming on the film sets built in the hangars, which is no way to run an airport!
Happily under new management my flight since was far more straight forward. The Ops manager Alan and his staff are incredibly helpful and welcoming. Prices (ex VAT) were 100 euros landing for the C340, with 88 euro handling and a pax charge of 10 euros for security. It was 75 euros overnight parking thus still much cheaper that DUB.
Outbound was back down the Liffey corridor at 1500 feet and then a direct to my IFR point at ENDEQ for the Q36 back towards WAL and home.
I stayed both at the old quaint Lucan Spa Hotel which is walking distance from airport for me or short taxi for most and thence 3 euro on the bus into Dublin! Also stayed in the centre of the city at the Trinity Townhouse Hotel, which was superb! Hopefully no need for Covid passports or Pax Locator Forms anymore, but Irish GARs are required 24 hours in advance as we are outside of Europe! UK GARs easy online.
Hope that helps
