For those of you who are talking about diversion fuel and don't have a good idea of airports in Texas, just an FYI post. There are a LOT alternates (runway length ~8000ft or longer) as close or closer than DFW. Three in Houston (Bush, Hobby and Ellington Field (NASA/military)), four airports in the DFW area (DFW, Love Field, Alliance and the Naval Air station in Ft Worth), San Antonio, Austin, Waco, New Orleans (La), Tyler, Longview, Shreveport (La), Corpus Christi, Victoria, and Laredo plus a LOT of others with shorter runways they could use in an emergency like the two in Conroe, College Station airport (Easterwood), Army airbase at Killeen, Stinson Municipal in San Antonio, Austin Executive, Beaumont, Baton Rouge (La) and Lufkin. This is also not a complete list just ones off the top of my head.
