Just got back from EGAC actually - though it was a great airport.
£16 for landing, 24 hours parking plus handling (my own bus to the terminal), and a lot of help from the dispatchers (thanks if you read this) with wx etc - wish every similar sized airport was as friendly. Plus only £6 taxi into town.
Weather was disappointing - didn't see a thing from about 1000' out of EGAC until descending over POL 2 hours later, but all went smoothly enough.
Will definitely be making a few more NI trips.
Thanks for your help chaps.
