(Adds UPS flights resume out of Houston airport)
Aug 31 (Reuters) - United Parcel Service Inc said one of its planes was due at Houston's main airport on Thursday afternoon and package trucks were making deliveries on routes in Corpus Christi as the company resumes some Texas operations halted by Hurricane Harvey.
UPS, the world's largest package delivery company, has restored service to more than 150 zip codes in Texas over the last 24 hours though operations remained at a standstill in storm-battered Houston and other Gulf Coast areas, UPS spokesman Matt O'Connor said.
The first UPS plane into Houston's George Bush Intercontinental Airport will land on Thursday afternoon and three flights were expected to depart Friday morning, O'Connor said. An airport official said limited flight operations were resuming at 4 p.m. local time on Thursday.
Two days ago, the storm stopped or sharply limited deliveries to more than 730 zip codes in Texas and Louisiana, he said.
"The safety of our employees comes first and we will be resuming service as soon as it is safe to do so," O'Connor said. "In Houston, that will come down to local areas that were impacted and how quickly water subsides."
Harvey came ashore over the weekend as the most powerful hurricane to hit Texas in a half-century. Days of heavy rains and flooding of streets, highways, and rail networks forced UPS and rival FedEx Corp to shutter facilities and cease delivery to huge swaths of southeast Texas and Louisiana.
UPS halted operations in Austin, northwest of Houston, and Corpus Christi, along the coast, before Harvey made landfall, O'Connor said. As of Thursday, package sorting facilities and deliveries resumed in Austin and in some areas of Corpus Christi.
"Now that the weather is subsiding in communities in Corpus Christi, and our employees are able to come back home, we will continue to resume service as it is safe to do so," O'Connor said. (Reporting by Eric M. Johnson in Seattle; Editing by David Gregorio and Steve Orlofsky)
