YVR - DFW - IAH advice
I will be making this trip in a few weeks... I understand I will be doing pre-clearance at YVR can I get some duty-free there and will I be able to transfer it a DFW .... I think it should work as I buy post security at YVR and if I understand correctly I should not have to repass security at DFW... Are my assumptions correct? Thanks.
Ps all on AA
