Has anyone travelling domestic in POM has this happen or heard of this rule? I had put my luggage through at checkin and as I was overweight, I grabbed 3 cans of food (as you do) and put in my carry on. When I went through security they said I wasn’t allowed to take cans onboard. I asked why not and they could not answer why not just kept saying not allowed. I asked to see paperwork saying I couldn’t take in carry on ( I know I know, fighting a losing battle) They took me back outside and I checked bag in. Checkin agent said cans could be classed as weapons. But what about the bottles of wine I had? I think I could do just as much damage with a wine bottle as a can of condensed milk. Does this happen domestically anywhere else in the world?
