Alitalia is temporarily suspending services. They've done this before, will do it again in conditions warranting such reaction from what I understand.
Expect, once flying is norm and load factors increase once again, for AZ to....
a) Increase JFK frequency to normal levels
b) re-instate MXP-SFO, MXP-HKG, and possibly the Kangaroo route again.
742's will be gone by mid '02 having been replaced by 777's. As others are saying, I wouldn't expect LAX to be one of the first destinations. If load factors are up again, and AZ wished to re-instate MXP-SFO, Expect SFO and JFK to get the first 777 service. They'll need capacity on the MXP-JFK and FCO-JFK routes and w/o 747's they'll have to run two 763's. So, I'd expect 777's to fly daily to JFK at first.
As far as MXP being a hub or not, expect it will continue. FCO seems to be the target of more growth lately tho.
Some see lines, others see between the lines.
