Flight 669 arrived at 1:37 p.m. to a traditional "shower of affection" from DFW's fire engines on the tarmac. The Airbus 330 has two classes of service.
"DFW was the top service for customers worldwide for KLM," said Jacques Malot, vice president of airport customer service in the U.S. for Air France/KLM. "Everything was telling us we had to return."
Over 85 percent of the customers on KLM flights connect through Amsterdam on to other destinations in Europe, Malot said. The service is expected to last through October.
Last year, KLM's service had load factors in the high 80s and low 90s, he added.
"We expect the same load factor or even more. The first flight was oversold and is arriving almost full," Malot said.
Eventually, DFW hopes KLM will keep its service year-round, said Luis Perez, vice president of air service development at DFW Airport.
"Of course, it's all based on economic factors here as well as Europe but they seem pleased with the results," Perez said.
