I was traveling with my father, who had wheelchair service, he was brought to the gate to wait for boarding. When Pre-boarding began, the agent started with individuals with disabilities or who needed assistance, it wasn't even 2-3 seconds, the next pre-boarding status was announced - active duty personnel - what made it worse, was that nobody came to either push the wheelchair or assist my father. so I had to help my father up and through the line, where there was already a line. So I wasn't sure what was the purpose of the pre-boarding, if there wasn't any order to it. Thankfully, it was the first time we've experienced this, hopefully, it's the last.
