时间很足够啊!!
取行礼和check in 行礼都在美国海关旁边 不用带着2个32kg的大箱子到处跑
after stepped out the plane from Ottawa
step 1: go get on the shuttle bus to the right terminal
step 2: follow the U.S.Custom sign
step 3: you will see the uniformed U.S.officer,show ur ticket & ID
step 4: pick up your luggages
step 5: clear customs (see the Inspector)
step 6: give your luggages to the person besides a luggage claim
step 7: go through security
step 8: check the monitor make sure your gate number is not changed
step 9: walk or run to your gate depends on how much time left
the most time consuming part is to clear the US custom (step 5), if you are questioned with tons of questions. try to shut them up by giving him/her your return ticket or electronic ticket and show no interest to permenantly stay in their coountry or find a job there.
