Aviation insider JonNYC reported on X that American Airlines is testing a pilot program at its Charlotte (CLT) hub that will base initial delay estimates on the scheduled arrival time of the originally assigned aircraft rather than issuing repeated optimistic updates. [^1]

Under the new pilot program, American Airlines will stick to its original delay estimate even on the rare occasions it finds an alternative aircraft, and its overall on-time performance may decline as a result. [^3]

Rolling delays may still occur in the future due to unplanned maintenance issues, severe weather, or air traffic control restrictions, according to the article. [^2]

JonNYC also said American Airlines plans further steps to end rolling delays, including more realistic scheduling on delay-prone routes and more proactive maintenance. [^4]
