All Texas air travelers should get to their airports earlier than usual Thursday.
That's after security was tightened at Dallas-Fort Worth International and Houston Bush Intercontinental airports after British officials broke up a terror plot.
US counterterrorism officials say that Fort Worth-based American and Houston-based Continental airlines were specific targets of the plot. London says the plan was to simultaneously blow up several jetliners en route to the US using explosives smuggled on board in carry-on bags.
At Dallas-Fort Worth International Airport, where American is based and hubbed, airport spokesman Ken Capps says extra police and
K-Nine units have been mobilized. Those units are patrolling terminals and parking garages.
US officials have banned all carry-on liquids and gels -- including beverages bought at airport concessions stands. Capps says baby milk or formula is still allowed when an infant is with an adult passenger, as well as insulin and prescription drugs when the name on the label matches that on the boarding pass.
Similar measures have been taken at Bush Intercontinental Airport in Houston, where Continental Airlines is based and hubbed.
Airport spokeswoman Marlene McClinton urged domestic travelers to arrive two hours before departure, and international travelers to allow three hours.
