fast dfw security line
 

iad has an unpublicized frequent traveler security line buried in the baggage pickup area. does dfw have any such facility.

i usually go through security around 6am, which is when we have a tsa shift change.

DFW has so many checkpoints, that security lines are rarely long. I typically see 2 minutes or less midday, up to maybe 10-15 during the Monday morning peak. The airport is so spread out that saving 10 minutes in line by using a checkpoint in another terminal really won't save any time.

That said, there's a checkpoint in the middle of terminal D under the hotel. It's not adjacent to any ticket counters, so during the rare cases when lines are very long (e.g. Holiday weekends), that may be your best bet.

With dozens of security lines, including the newest one in the middle of D at the hotel, I don't recall any more than a slow shuffle of a couple of minutes at any of them. Certainly, the new Skylink has reduced confusion in moving between terminals within security to a minimum (both in time and effort), eliminating the one "long" walk, "High A" to "Low C"
