Update: Southwest has resumed flights after the nationwide grounding.

Southwest Airlines planes were stopped from taking off nationwide for what the airline called an intermittent technology issue, causing more than 1,500 flight delays Tuesday just four months after the carrier suffered a meltdown over the Christmas travel rush.

Southwest and the Federal Aviation Administration said by late morning on the East Coast that the pause had been lifted.
