These airlines and airports have the most flight delays and cancellations

Using data from the Department of Transportation's Bureau of Transportation Statistics (BTS), KXAN took a look at which airports and airlines have seen the most delayed and cancelled flights this year.

AUSTIN (KXAN) — Millions of Americans are expected to take to the skies this Labor Day weekend, with passenger totals anticipated to reach pre-pandemic levels.

Long check-in and security lines aren't the only things travelers have to contend with. Delays and canceled flights can cause major headaches too.

Using data from the Department of Transportation's Bureau of Transportation Statistics (BTS), KXAN took a look at which airports and airlines have seen the most delayed and canceled flights this year.

BTS uses arriving flights when looking at delays and cancellations. A flight is considered delayed if it arrived at the gate 15 or more minutes after the scheduled arrival time, as reported by airlines.

Austin-Bergstrom International Airport

AUS consistently sees more than 70% of arriving flights reaching the gate on time. So far this year, May is the month with the most on-time arrivals, 79%.

In June, that dropped to 70%, with more than a quarter of all flights delayed. February was the month with the most cancellations — about 8% — likely impacted by a major winter storm that brought snow, sleet and freezing rain to Austin.

When it comes to airlines, JetBlue Airways and Hawaiian Airlines have seen the most delays at AUS so far this year. More than a third of all arriving flights on both airlines were delayed between January and June.

JetBlue had the lowest proportion of on-time arrivals, with fewer than 60% of all flights reaching their gate within 15 minutes of the scheduled arrival time.

Frontier Airlines has the best on-time performance at AUS, with about 82% of flights on time between January and June.

When regional and subsidiary airlines are included, Endeavor Air takes the top spot, with 86.6% of arrivals on time. The airline is owned by Delta Air Lines and operates as Delta Connection.

Republic Airways, which operates flights as American Eagle, Delta Connection and United Express, is the top offender in Austin for most cancelled flights, with 6.7% of all arrivals cancelled between January and June. Low-cost carrier Allegiant Airlines is right behind, with 6.3% of flights cancelled.
