还有就是机票是国航北京到温哥华的双程， 所以转机定的是温哥华到多伦多单程， 看加航的网站说Airport same-day changes are subject to availability and are permitted only for same-day flights at a fee of $150 CAD/USD per direction, per passenger, except for passengers travelling on a flight between Toronto and Montreal, or Toronto and Ottawa (connecting flights excluded), for whom the flat fee is $75 CAD/USD. Same-day flights only.
那我要是误机， 就要付$150 CAD？
