On Time Arrival Rate Climbs to Nearly 80%
The nation's largest airlines had a rate of on-time flights this
past April that was higher than both the same month last year and
the mark posted in March 2009, according to the Air Travel Consumer
Report released today by the U.S. Department of Transportation
(DOT).
According to information filed with the Bureau of Transportation
Statistics (BTS), a part of DOT's Research and Innovative
Technology Administration (RITA), the 19 carriers reporting on-time
performance recorded an overall on-time arrival rate of 79.1
percent in April, better than both the 77.7 percent on-time rate of
April 2008 and March 2009's 78.4 percent.
The monthly report also includes data on lengthy tarmac delays,
flight cancellations and the causes of flight delays by the
reporting carriers, as well as reports of mishandled baggage filed
with the carriers, and consumer service, disability and
discrimination complaints received by DOT's Aviation Consumer
Protection Division. It also includes reports of incidents
involving pets traveling by air, as required to be filed by U.S.
carriers.
In April, the carriers canceled 1.5 percent of their scheduled
domestic flights, a lower rate than both the 1.7 percent
cancellation rate of April 2008 and the 2.1 percent rate posted in
March 2009. There were five flights with tarmac delays of four
hours or more in April.
The carriers filing on-time performance data for the month
reported that 7.40 percent of their flights were delayed by
aviation system delays, compared to 7.29 percent in March; 6.19
percent by late-arriving aircraft, compared to 6.49 percent in
March; 4.78 percent by factors within the airline's control, such
as maintenance or crew problems, compared to 4.84 percent in March;
0.69 percent by extreme weather, compared to 0.62 percent in March;
and 0.03 percent for security reasons, compared to 0.04 percent in
March. Weather is a factor in both the extreme-weather
category and the aviation-system category. This includes delays due
to the re-routing of flights by DOT's Federal Aviation
Administration in consultation with the carriers involved.
Weather is also a factor in delays attributed to late-arriving
aircraft, although airlines do not report specific causes in that
category.
Data collected by BTS also shows the percentage of late flights
delayed by weather, including those reported in either the category
of extreme weather or included in National Aviation System delays.
In April, 44.38 percent of late flights were delayed by weather, up
17.13 percent from April 2008, when 37.89 percent of late flights
were delayed by weather, and down 2.42 percent from March when
45.48 percent of late flights were delayed by weather.
