Cumulative YTD US DOT stats are only available through May, but show that for the Jan-May 2023 period, UA was #5 for on time arrivals and #8 for cancellations (these numbers include regional ops), where #1 represents the best performance ranking and the rankings are by % of total ops.
For on time performance , DL was #1 and AA #3, and for cancellations, DL was #3 and AA #4.
