I dont seem them operating from anywhere else to AGP and FAO as they seem exclusive to DUB.
Ryanair do some charters from sports events but not via a travel agent and they can be quite expensive.
Last year an Irish league team was playing in Northern Spain in a match which would have put them into the champions league.
Ryanair put on a charter flight and charged a huge amount. Needless to say people copped on and the flight had to be cancelled.
