What do late arrivals look like? Not what the FAA calls “late” – no 15 minute grace period here! The schedule is the schedule, especially when it is published. We grant airlines slack because there are exogenous factors that throw off schedules, but when we average out this into the YTD numbers, late is late.
This what 2019 YTP November arrivals look by aircraft type.
Also what the score looks like by airline and specific tail number YTD November.
Finally, a breakdown by month for 2019. There seems to have been a big improvement lately.
And in case you were wondering when NOT to fly, this table tells you clearly.
