Cork-Lisbon
Cork-Lisbon seems a strange choice. Lisbon is quite a niche destination and I'm not sure whether it'll work from Cork. Prague on the otherhand is a popular city city break destination as well as attracting a lot of immigrant traffic. Lisbon definitely won't work as a winter destination. Lets hope the gamble works.
On another note, EI have released their summer programme for next year up to June. Its similiar to this year. Differences include:
Barcelona up to 4 weekly
Alicante down to 3 weekly
Birmingham down to 4 weekly
Berlin down to 2 weekly
Lanzarote operating 1 weekly for the summer - the first time EI have operated Lanzarote during the summer.
