Well, I just recently traveled from Houston to Mexico City.. I requested a visual check of my PC and film...and it was a no go, I asked to talk to 3 different supervisors, I was nice and polite and everytime I was denied a visual check I asked for the next person higher. They all told me the same....new rules, everything goes through the x ray. When I stated I thought they were mistaken and that visual checks were still allowed they were adamant in their attitude that no more visual checks, of course when I asked them to show me the ne regulations they were unable to do so, but in the end what do you do? you have the choice of missing your flight, keep arguing or passing your film through the x ray and hoping it does not get exposed. If any of you out there are counting on getting a visual check you might as well forget it.
