Brasilia International (BSB)
Worst Departure Rank: No. 1
In 2007, less than 27% of Brasilia's flights left on time. Average wait time: 52 minutes. Not good for a capital city airport with more than 10 million passengers passing through per year. For airports serving 10 million passengers or more, Brazil's airports had the worst track record for on-time arrivals and departures in 2007.
Beijing Capital International (PEK)
Worst Departure Rank: No. 2
Beijing hosts the summer Olympics in 2008, and if last year's records are any indication, the city's main airport has much improvement to make on flight delays. In 2007, barely more than 33% of its flights took off on time. PEK is the busiest airport in China, serving nearly 49 million passengers in 2006, the most recent figures available. A major expansion is planned for later this year.
Sao Paulo Guarulhos International (GRU) and Congonhas International (CGH)
Worst Departure Rank: No. 3 (GRU) and No. 4 (CGH)
In 2007, there was only a slight difference in the on-time departure records for Sao Paulo's two main airports, so we group them together here. Only 41% of the flights at GRU took off on time, 43% for CGH, the busier of the two for passenger traffic. Both are managed by Infraero, Brazil's airport authority.
Cairo International (CAI)
Worst Departure Rank: No. 5
With 10.8 million passengers in 2006, Cairo is home to Africa's second busiest airport, after Johannesburg. But it's the continent's worst for reliable departures, with only 47% of its flights leaving on time in 2007. The average wait: 43 minutes. For arrivals, Egypt's main airport isn't much better. Nearly 44% of its flights did not arrive as scheduled last year.
Paris Charles de Gaulle International (CDG)
Worst Departure Rank: No. 6
Because it is so vast, France's main international airport is notorious for long distances between terminals. Good thing then that barely 50% of its flights departed on time in 2007, making it Europe's worst major airport for on-time departures. Travelers didn't have much time to tarry, however: More than half of those late flights took off less than 30 minutes after their scheduled departure.
Chhatrapati Shivaji Mumbai International (BOM)
Worst Arrival Rank: No. 1
India's busiest airport in terms of passengers (21.4 million in 2006) is also the world's worst for on-time arrivals. Last year, slightly more than 44% of its flights arrived as scheduled, with an average delay of 45 minutes. Departures from Mumbai were much more reliable, with 72% leaving on time.
Delhi Indira Gandhi International (DEL)
Worst Arrival Rank: No. 2
When it comes to late arrivals, India's second busiest airport in terms of passengers (19.4 million in 2006) looks strikingly similar to the busiest, in Mumbai--just more than 45% of the flights arrived on time last year. Airport authorities are in the midst of expanding most of India's major airports to keep pace with the country's astounding growth.
Sao Paulo Congonhas (CGH)
Worst Arrival Rank: No. 3
As the third worst major airport for on-time arrivals and fourth for on-time departures, Congonhas deserves the title "World's Most Delayed Airport." Only 54% of its flights arrived as scheduled in 2007. Of those, 40% were at least 45 minutes late. Sao Paulo's other major airport, Guarulhos, also had difficulties with on-time arrivals--just 58% of its flights arrived as scheduled last year.
New York LaGuardia (LGA)
Worst Arrival Rank: No. 4
In the United States, New York's airports have become synonymous with delayed flights as the skies become crowded with commercial, cargo and corporate jets. In terms of on-time arrivals, the worst by a hair is New York's LaGuardia, with slightly less than 58% of all flights arriving on time in 2007, with an average wait time of more than an hour.
Newark International (EWR)
Worst Arrival Rank: No. 5
Busier than LaGuardia (36.7 million passengers in 2006, compared to LaGuardia's 26.5 million), Newark International is only slightly better than the New York Airport in terms of flight delays. Slightly more than 58% of its flights arrived on time last year. With 22% of its flights arriving at least 45 minutes late, Newark is the worst among the U.S.' major airports for excessively delayed arrivals in 2007.
A bit interesting huh?
