不知为什么 所有分段出來都不見了。加上中文也没用。 湊合着看吧。
只有两个大机埸有航班往 Trieste 还很大可能不是 Daily flight. Rome and Frankfurt, ITA (the old Alitaria) and Lufthansa

由倫敦 you will need to take Ryanair and departs from Stansted, one of the smaller airports in London. 如果你美国飞倫敦 你需要去 Stansted 飞 Ryanair, 不切实际。
另外, Trieste 离 威尼斯大概二小时火車。 Venice has its own Int'l airport, 威尼斯有很多很多很多國际航班。
IIRC Delta has direct flights to Venice. You can also easily use LHR, then fly to Venice. From Venice take a train to Trieste.
在 Venice and Trieste has regional trains, 慢車 可以現塲買票。
个人覚得 应该飞威尼斯 然后坐火車 看飞机和火车班次决定你飞威尼斯的航班。飞罗馬要坐飞机 火車时间太長了。
友情提示 - when you dont know what airlines serve a particular airport from where? Google the destination airpirt and read the Wiki of that airport. 通常可以知道应怎樣飞才合理。
