Houston’s two airports have reopened in the wake of Hurricane Harvey, but it will take a while longer for airlines to resume full service to the still-waterlogged Texas city.

Operations resumed at George Bush Intercontinental Airport on August 30 and at William P. Hobby Airport on September 2, including domestic and international flights.

Full flight schedules are not expected to resume until the end of this week, however.

More than 12,000 flights were cancelled as a result of the major hurricane, which brought major flooding to Houston and a swath of the Gulf coast reaching into neighbouring Louisiana.

British Airways began resuming service to Houston last weekend, while some domestic carriers expect to be back to full operations by the coming weekend.

The largest US airline, Southwest, which is based at Hobby, plans to be back at 100 per cent of its schedule by September 9. United Airlines is projecting to return to normal service at Bush by September 8 – the airport is United’s second-largest hub.

The last update from the airport, posted on September 1, advises travellers:

“Contact your air carrier for specific flight status updates regarding your flight. Only those with a ticket for a confirmed scheduled flight should come to the airport.

“Many roads around the City of Houston are still unsafe for travel, therefore, we urge all passengers to take their time arriving to the airports and to solidify a safe route to and/or from our facilities.”
