If Frontier had accepted your bag and checked you in, you would now be complaining about the security people who wouldn't let you cut to the front of the line at security because your flight was boarding?

I'm a paranoid traveler when it comes to time, I have been from my house, through security, and at the gate at DTW in 1/2 hour; but I normally try to get there to the airport at least an hour and a half early before my flight, time enough to check e-mail and have a drink at the WC.

People who show up late and expect the airline/airport staff and their fellow passengers to go out of their way to make their flight are one of the biggest annoyances of travel.
