Swissgabe, are you sure with your informations about MAS at ZRH? Where did you see that?
In my opinion, this is a bit weird to replace the B772 with an even bigger B744, if the loads are really a problem on the KUL-ZRH leg. How much pax would MAS need on the ZRH-FCO leg to justify such a flight?
Anyway, as a spotter - on the other hand - this gives me the chance to take pics of a new airliner/livery.
As for Ryanair to ZRH: I doubt it, given that Ryanair operates smaller airports and not hubs. ZRH isn't really very good for low fare airlines, Easyjet beeing perhaps an exception, as they are very good established in Switzerland. VEX on the other hand has already cut one of their 3-daily BRU-ZRH flights. GO was also only 6 months in ZRH.
