Sorry I didn't realize Aer Lingus hadn't joined yet. They intend to in the future according to a press release on their web site at http://www.aerlingus.ie .

For great deals out of the London area, contact Trailfinders http://www.trailfinders.com - they're an established well-known travel agent using consolidator fares in the UK. Also, check out http://www.tiss.com

Sorry for the mix-up!!
