I really wish all the GS would complain about the lack of implementation on this. As a 1K, I don't feel like I'll be taken seriously. On my CMH-DEN flight last week there was no way for people to preboard. They have three gates at the end of the hall. The GA merged all the pre-boards together, and as I scanned my BP, I told him that he needs to pause between each of those groups. He gave me a 'whatever' look. This is what you get from the lowest bidder handling ground ops when unemployment is under 4%.
IF GS complain, we might get some better implementation.
