The Emerald Isle is no longer a part of the United Kingdom, so this tax doesn't apply, the Irish do have a similar tax for passengers, but its only around 2 Euro (??) and doesn't apply to corporate aviation.
Shannon is an excellent technical stop as its a quiet airport and rapid turnarounds are easy. You should try it.
Cldrvr, thanks for that, the fact remains that a flight this month can cost us 20,000 UK more than last month, we can't avoid this payment as thats where the passengers want to go, but if we can avoid the country during tech stops, then we might gain one ounce of personal satisfaction that we do have a means of protest
