Workers at Chicago-based United Airlines will get bonuses for hitting its monthly on-time rate goal in July, but only because the airline changed its own target.

United, which experienced operational woes in recent years and has since pledged to land more flights on-time, was on time 76 percent of the time in July, according to FlightStats. While that falls well short of its previous goal of exceeding 80 percent on-time — and just matched the average of all North American airlines — it ranked second-best among the four major U.S. airlines, lagging Delta Air Lines but beating American Airlines and Southwest Airlines.

And that’s the new goal this year — to rank at least second of the four major airlines. It’s the highest on-time rate for July in four years, the airline said.
