I think FCO would be the next port of call.
CIA is full and they can make three strokes with one move:
1. Compete better than BA on the LGW route
2. Stick it to Alitalia where it hurts
3. Grow in the Rome district
Hopefully U2 will be able to expand in Italy and we may finally see to the end of Alitalia. Personally, I hope that Alitalia disappear and Air One are able to step in but that is very unlikely!
