In the estimation of frequent flier Chris Martin, Houston's continually expanding William P. Hobby Airport soars as an "exciting and excellent" hub for business travelers.

Martin is senior vice president of global business development in the Houston office of travel agency Wings Travel Management and one of the leaders of the Houston-based Texas Business Travel Association. He says Hobby Airport's location — seven miles southeast of downtown Houston — and its low-cost flight options hold great appeal for business travelers, especially those with tight travel budgets. And that appeal continues to grow, thanks in part to initiatives at Hobby undertaken by Southwest and Allegiant airlines.

On January 8, Dallas-based Southwest, the No. 1 carrier at Hobby as measured by passenger traffic, unveiled a $125 million, 240,000-square-foot maintenance complex at the airport. It's the largest maintenance facility in Southwest's network. The complex includes a 140,000-square-foot hangar for aircraft maintenance.

"The new hangar continues to showcase our dedication to Houston," Southwest spokesman Dan Landson says. "We've grown continuously over the last several years, and we see more growth in our future, which the hangar will help facilitate."

Southwest's new maintenance complex speeds up airline operations in Houston and helps "get travelers on their way more quickly," Landson says.

At the public debut of the maintenance complex, Southwest Chairman and CEO Gary Kelly told reporters that the airline plans to add a "significant" number of flights at Hobby over the next five to 10 years. He suggested that Houston's beefed-up flight schedule could include brand-new routes to South America.

"We see a lot of opportunity to continue growing," Landson says, "and linking Houston to the places that our customers want to go — whether domestically or internationally."

Today, Southwest offers nearly 200 flights a day from Hobby to almost 70 destinations in the U.S., Mexico, the Caribbean, and Latin America. Hobby opened a $156 million, five-gate international concourse in October 2015.

Six days after Southwest took the wraps off its new maintenance complex, low-cost airline Allegiant said that beginning this May, it's launching seasonal twice-weekly service at Hobby with nonstop flights to Asheville, North Carolina; Destin-Fort Walton Beach, Florida; Knoxville, Tennessee; and Savannah, Georgia. No airlines at Hobby currently serve those destinations.

Allegiant will become the fourth airline to operate at Hobby. Aside from Southwest, American and Delta airlines currently fly out of Hobby, but Southwest is the only one with international service. Last year, JetBlue shifted its Houston operations from Hobby to the larger George Bush Intercontinental Airport.

In 2018, Hobby served almost 14.48 million passengers, up 7.7 percent from 2017 and surpassing 14 million for the first time. Figures for 2019 aren't available yet.

Any increase in passenger traffic at Hobby would certainly be propelled by time-constrained business travelers. In a ranking released January 29 by personal finance website FinanceBuzz, Hobby flies into the top spot on the list of the best U.S. airports if you're running late for a departing flight. To come up with the ranking, FinanceBuzz looked at data for the country's 45 busiest airports.

FinanceBuzz says Hobby's low average wait time at security checkpoints, just under 14 minutes, contributed to its No. 1 ranking.

"The chances of catching Hobby at its busiest are pretty low, and its relatively small number of departing passengers each day helps the airport from getting bogged down with too many travelers," FinanceBuzz reports. "While it's lower percentage of on-time flights might hinder those who are punctual, [this] can be the difference between catching or missing a flight for those running late."

By comparison, Bush Intercontinental ranked eighth on FinanceBuzz's list of the worst U.S. airports if you're running late. It's weighed down by an average 25-minute wait at security checkpoints, according to FinanceBuzz.

"Once you get through security, you've got the sixth-largest terminal on our list to navigate, which puts this airport as one of the worst for late travelers," FinanceBuzz reports of Bush Intercontinental.
