Kansas City, Mo ? American Airlines Inc. expects to decide the fate of three overhaul bases, including one at Kansas City International Airport, by the end of the summer, Mayor Kay Barnes said.

Barnes and other city officials met with an American senior management team Tuesday at its Fort Worth, Texas, headquarters. The trip was part of an ongoing effort to persuade the airline to keep its Kansas City maintenance operations.

Barnes said Wednesday that the meeting went well, although nothing was resolved.

American spokesman Tim Wagner said he was unaware of any timetable that called for the airline to make final decisions about its maintenance operations in the next several weeks.

“We haven’t really talked about a timeline,” he said. “If that was discussed at (Tuesday’s) meeting, I don’t have any information to confirm that.”

American has about 2,000 employees at its Kansas City overhaul base, which is owned by the city and leased to the airline. American also operates and leases maintenance bases in Fort Worth and Tulsa, Okla. The Tulsa maintenance base is American’s biggest operation with more than 8,000 employees.

Barnes said Kansas City plans to submit a proposal to American as early as next week that will address how the city’s facility may be upgraded.

“Our strength is our work force,” Barnes said. “They’re the best. Our location also is an asset. Our weakness is the physical age of our facility.”

An expansion at the base was derailed after the 9-11 terrorist attacks.

Butch Sponaugle, president of Transport Workers Union Local 530 in Kansas City, said how to pay for an upgrade of the Kansas City facility will be an important part of the discussions between the city and American.

“That’s the main issue how to pay for the badly needed work on the overhaul base,” he said.
