Story has been updated to include Delta share price and IATA's withdrawal of the sizing initiative.
NEW YORK ( TheStreet) -- Delta ( DAL) said Tuesday it was unhappy with an airline industry trade group's effort to implement a smaller standard size for carry-on bags, and now the trade group has halted the effort.
The Geneva-based International Air Transport Association, which represents 258 carriers in 117 countries, said last week that it has initiated a program called "Cabin OK" to reduce bag size from the standard used by most U.S. carriers.
On Wednesday, IATA announced it was "halting the rollout "and beginning a comprehensive reassessment in light of concerns expressed, primarily in North America."
Perhaps the most significant opponent of the program was Delta, which declared in a press release Tuesday that it "has no plans to reduce the size allowance for carry-on bags.
"We are concerned IATA called for a change without input from airlines," Delta said. "Our focus and investment in the carry-on experience have been on installation of larger bins on domestic and international aircraft, and will continue to be on delivering the reliable bag service -- checked or carry-on --- that Delta customers have come to expect."
