Hello! I always fret about security, of course, when I travel with children, but I was thrilled at how seamless the whole thing was at the Frontier Airlines PHX Terminal the personnel at Terminal 3 did a very good job at keeping everything organized, and even though there was a queue of sorts, it was moving efficiently. We arrived early just to be on the safe side, but in all honesty, the waiting time was not that bad at all. It was so great not to be rushed or stressed and to make the beginning of our trip that much less complicated!
