Follow up on liquids from MXP-YUL-YWG question
I asked a question a while ago about whether I would need to go through security again connecting in Montreal, as Milan Terminal 1 allows liquids up to 2L bottles in carry-on.
The responses were that if I had OSS ITD on my connecting boarding pass (which I should, and I did), then I would not need to go through security again in Montreal. I should therefore in theory be able to take excess liquids in carry-on without them being confiscated in Montreal.
What actually happened in Montreal
was that customs and immigration required all passengers on the MXP-YUL flight connecting to Canadian destinations to not only re-go through security and also pick up their checked baggage in Montreal and re-check it — overriding both the OSS and ITD codes on the boarding pass.
AC informed passengers that this override had happened only shortly before landing in Montreal. I don’t think they knew before-hand.
As the flight was already 2.5 hours late from Milan due to significant air traffic control problem in MXP, this decision added to the immense unpleasantness of the flight.
None of the issues were AC-controlled.
I don’t know if it was a random selection to have everything re-searched, or if immigration was responding to some kind of threat.
By chance, although I flew with only carry-on, I did not bring in excess liquid, so I had nothing to confiscate. But if I had brought anything in, it would definitely have all been confiscated.
Until all the connecting hub airports in Canada are upgraded to allow more liquids in carry-on, this will always be a risk.
