Aena's stats for April show the following for the new Canary Island routes from Knock:
Tenerife 1,093 Pax 72% LF
Gran Can 858 Pax 57% LF
Lanzarote 1,070 Pax 81% LF - assuming first incoming flight was empty or close to it
Lanzarote doing very well in its first month of operation, Tenerife doing fine, Gran Canaria still lagging behind a bit.
