The Milan and Rome flights may or may not be upgraded to 777s in the near future. They do have two of the triple-7s being delivered in 2002, but it looks like MXP and FCO are set to recieve 767-400ER service. I always thought that the two 777s on order would be for those very two cities because Continental ordered them right after they anounced the HKG flight, which would take awayy the triple sevens from Rome and Milan. Oh well, maybe we'll seea Newark-Osaka route with them, Continental Micronesia has soem frequncies that they could spare in order to make this flight work because Continental already holds the right to fly between the two cities.
Houston-Frankfurt is unpredictable. Expect a 767-200ER initially, and if loads prevail a 764 should be a nice upgrade for a good market. Rome, Amsterdam, and Madrid will most likely be served with 767s, and the latter one making a good 767-400ER because of LatAm connections.
