How long will you wait in the TSA security line?

(CNN)I'm flying out of the busiest passenger airport in the world on Friday morning, and I don't know how early to get there for my flight.

You'd think a travel writer would know.
But I've seen the same tweets as everyone else about long, long security lines at airports all over the country, interspersed with tweets about short lines at the same airports.
Which lines will you and I face?
    The U.S. Transportation Security Administration and Congress are working on staffing solutions, increased airline collaboration and boosts in funding to address the snarl that is summer air travel.
    But those much-needed solutions definitely won't come before Friday.
    So when should I arrive at Atlanta's Hartsfield-Jackson International Airport? And when should you arrive at your airport?
    The TSA advises arriving two hours early for domestic flights and three hours early for international flights. But those early morning security lines sure look busy. I'm not so sure that two hours is enough if you have an early morning flight.
    The My TSA app shows wait times at airports around the country, but it depends on travelers posting information (so please do it).
    Airport officials are starting to measure TSA wait times in real time -- something the Atlanta airport has been doing for years -- and posting them on social media.
    I know most people can't simply reach out to the TSA and the airlines for answers, so I decided to do it for all of us.
    Frankly, I think Atlanta-based TSA spokesman Mark Howell sounds a little too upbeat when I pick up the phone to talk to him.
    "Friday's going to be a busy day," Howell says cheerfully, pulling up some numbers on his computer.
    "We're projecting around 80,000 passengers (coming through Atlanta airport security) compared to a normal Friday of 73,000 to 75,000."
    Fellow passengers: You should note that his projections for the next two Fridays also show 80,000 people daily. Busy is the new normal.
    Peak flying times are early morning and early afternoon, Howell notes, which is why he likes that my flight is scheduled for 11 a.m.
    "We're recommending two hours for domestic flights, three hours for international," he says. "Wait times will be long, but they should be better by that time of the morning."
