In the first quarter of 2012, 82% of scheduled flights
were on-time, the same as in the first quarter of 2011,
equalling the highest level this century. Average delay was
also maintained at 10 minutes.
Manchester and Heathrow had the worst on-time performance
(79%) for scheduled flights, whereas Glasgow, Newcastle,
London City, Birmingham and Edinburgh all achieved an
on-time performance of over 85%.
Data from the UK Civil Aviation Authority (CAA) released
today shows that between January and March 2012, the
overall on-time performance (defined as the proportion of
flights arriving or departing early or up to 15 minutes
late) of scheduled flights at the ten UK airports monitored
was 82%, the same as in the first quarter of 2011. The
average delay across all scheduled flights monitored was
ten minutes, the same as in the first quarter of 2011.
In the first quarter of this year, at ten airports the
punctuality of 307,000 scheduled and 11,000 charter
passenger flights was measured, which represents a 2.0%
decrease in scheduled flights and a 6.4 % decrease in
charter flights, compared with the first quarter of
Commenting on the figures, Iain Osborne, CAA Group Director
for Regulatory Policy, said: "It is excellent to see that
airlines have managed to maintain their record performance
this year, but given the decline in flight numbers, we
might have hoped to see punctuality improving even
On-time performance (defined as early to 15 minutes late)
for scheduled flights at London airports increased by one
percentage point to 82% but the average delay increased by
one minute to 11 minutes, between the first quarter of 2011
and the first quarter of 2012. Over the same period, both
Gatwick and Luton saw an increase of two percentage points
in on-time performance to 84% and 82% respectively.
Stansted's on-time performance fell by two percentage
points to 84%, while Heathrow's and London City's
performance was flat year on year with 79% and 87%
respectively of their flights being on-time.
Overall, both the on-time performance and the average delay
for scheduled flights at the regional airports monitored
stayed at the same level in the first quarter of 2012
compared with the same period in 2011. On-time performance
fell by two percentage points at Manchester to 79% but
increased by one percentage point at Edinburgh, Birmingham
and Newcastle to 86%, 87% and 88% respectively and by two
percentage points to 88% at Glasgow.
The proportion of on-time charter flights fell by one
percentage point to 71%, in the first quarter of 2012
compared with the same period of 2011. The average delay
across all charter flights monitored in the first quarter
of 2012 was 22 minutes, which equalled that recorded in the
first quarter of 2011.
Destinations with most passengers
Among the 75 scheduled international destinations with the
most passengers in the first quarter of 2012, flights to
and from Dubai recorded the worst on-time performance of
66% and flights to and from Toronto the highest average
delay of 20 minutes. Flights to and from Rotterdam achieved
the best punctuality with an on-time performance of 93% and
the lowest average delay of 5 minutes.

2. The CAA statistics on punctuality of passenger flights
at 'London Airports': Heathrow, Gatwick, Luton, Stansted
and London City, and 'Regional airports': Manchester,
Birmingham, Newcastle, Edinburgh and Glasgow cover both
arrivals and departures. Actual times of operation are
derived from air transport movements returns made to the
CAA, which are compared with planned arrival and departure
times supplied by Airport Co-ordination Ltd. Figures for
Glasgow Airport became available in July 1993, Newcastle
and Edinburgh airports from April 1996 and London City from
April 1997. All other airports report from April 1989.
3. In these punctuality data, 'delay' is recorded
as the difference between an aircraft's scheduled and
actual arrival or departure time at the airport terminal.
It does not therefore measure any delay, such as that due
to congestion, which has already been allowed for in the
planned flight times of the service.
4. Punctuality data are published monthly and annually in
summary and in full on the CAA website: www.caa.co.uk/punctuality.

Civil Aviation Authority, Aviation Intelligence, K4, CAA
House, 45-59 Kingsway, London WC2B 6TE, telephone 020 7453
5. On-time performance and delay is calculated from the
scheduled on-stand time (provided by Airport Co-ordination
Ltd.), the reported runway time (provided by the airport)
and the expected time an aircraft takes to travel between a
stand and the runway (taxiing time - calculated from
historic data). The use of average taxi times is sufficient
for calculating an aggregate level of on-time performance,
but would not be suitable for reviewing the punctuality of
an individual flight.
6. In 2009, the CAA, in consultation with the airports,
undertook a review of the taxiing time assumptions, and
updated the values used for quarter 1 2009 data onwards. To
ensure that the comparison is like-for-like, the
punctuality data for 2008 has also been recalculated using
the revised taxiing time assumptions.
7. It should be noted that the statistics in this notice
cover only those flights which were operated; they do not
cover those flights which were cancelled. Delays can occur
for a variety of reasons. Operating circumstances, both
within and without the airline's control, also vary by
route and by type of service. These tables are not intended
and should not be treated as a direct comparison between
scheduled and charter services.
8. The CAA is the UK's specialist aviation regulator.
Its regulatory activities range from making sure that the
aviation industry meets the highest technical and
operational safety standards to preventing holidaymakers
from being stranded abroad or losing money because of tour
