The April 2016 airline on-time arrival numbers are in today from OAG. And the results show Chicago's very own United Airlines, is starting to look like a real contender.

United has struggled for some while to get near the top of the leader board in the hotly-contested on-time arrivals race. But in April, United was — hold on to your boarding passes! — a solid No. 2 in the rankings among the nation's four largest domestic carriers. United got 83 percent of its flights to the gate on time in April, a jump of 4.5 percentage points from its fourth-place finish in March, with a 78.5 percent on-time arrival result. The carrier has repeatedly noted it is relentlessly focused on improving on-time performance, and the results are starting to show. A flight is deemed on-time if it arrives at the gate within 14 minutes of its scheduled arrival time.
