Similar questions has been asked and answered elsewhere in TA so I apologise if I am repeating, but there is a slight variance to the ones I have read...we are travelling to Canada to take a 3 week tour and will arrive about a week early. We plan to arrive in Vancouver from Sydney on Air Canada (scheduled in at 7.30am) and would like to then go to San Francisco the same day (and Las Vegas) before returning for the tour.
If we arrive on an Air Canada flight and depart Vancouver for San Francisco on an Air Canada flight - assuming it is possible for Air Canada in Sydney to check the bags all the way to San Fran (I will phone then tomorrow to ask...) .. must we clear Customs and Immigration in Vancouver before boarding a flight to the US? If the bags are checked all the way through, it is possible for us to go from the arriving flight to the departing flight without clearing Customs / Immigration?? If not, I assume we will have to allow 4 hours to go out and back in (as mentioned in other posts). The only reason I ask, other questions in the forum seem to have involved two different airlines and I was hoping Air Canada / Air Canada may give us a better outcome.
Any advice most appreciated, as always.
