比起匆忙的飞机旅行来，坐火车既便宜又舒服（英语翻译）

上面的不对,不可以用TO的.COMPARE TO 是比喻为的意思
Comparing with the haste of traveling by air, riding a train will be both cheap and comfortable.

Compared to the rush to air travel, ride the train will be cheap uncomfortable

Comparing with the hurry airplane trip, riding a train is cheap and comfortable~

楼上的一定是机译

Travel by train is economical and comfortable compared to a hasty trip by plane.

(补充：compare to 和 compare with 都有比较的意思。可以参考《朗文当代英语词典）
