Surprisingly, we had no trouble with TSA in either PDX or PHX, but I had a 15 minute argument with the Mexican screeners at the gate at PVR, who insisted all liquids must follow the 3-1-1 rule, INCLUDING medications. I politely disagreed and requested a supervisor be summoned. He repeated the same rule and of course, blamed TSA for the silly liquid rules. In the end, they let me take the meds on board, probably because we were the last to board and they wanted to close the flight.

My question is: who was right and how would you know? I'm not sure TSA rules apply to screening in PVR. If they do, then the TSA website clearly states:

Declare larger liquids. Medications, baby formula and food, and breast milk are allowed in reasonable quantities exceeding three ounces and are not required to be in the zip-top bag. Declare these items for inspection at the checkpoint.

2 x half-full 6 oz bottles of kids' cold meds seems "reasonable" to me.
