Even in 2023, delays were not a uniform experience with US airlines seeing 21.3% of flights delayed while global Q4 2023 reached 28% delayed flights. Delta posted a 16.8% delay rate and Southwest still managed 77.5% on time performance, yet airports like LAX averaged 24 minutes of delay per departure and ORD hit 31% during winter.
