Low fuel emergency in DFW

It takes less time to fit the Tulsa to DFW flight into the
flow of traffic than it does to turn 12-30 airplanes out of
the way to turn the airport around. DFW, unlike many
smaller airports never has a slack time, there are always
long sequenced flights.
Departing Tulsa, by jet, to DFW is not a long flight...why
did they have a "fuel emergency," did they depart without
fuel, did they have a leak?
If the flight had insisted on landing 17, then it could
easily have taken 30 minutes to get them a clear shot at the
runway.

They do this all of the time when a thunderstorm passes over the
airport. There are procedures to interrupt traffic flow for periods of
time such as this.

If the flight had insisted on using 17C, the only time it takes is for
the airplane to get to the runway. There is no extra 30 minutes. Where
do you get that from?
