OAG Turnaround Tables 2018 Reveals Arriving and Departing On-Time Performance Variances for World’s Largest Airports

OAG,the global leader in flight information, has released a new on-time performance report, the OAG Turnaround Tables 2018. The inaugural report ranks the world’s largest airports, as defined by number of scheduled flights, based on the variance between the average on-time performance (OTP) of flights arriving at an airport and the average OTP of flights departing from the same airport. The results are pulled from aviation data between January 1, 2017 through December 31, 2017.

An airport’s turnaround variance can be either positive or negative, depending on whether more flights arrive or depart late. Moscow’s Sheremetyevo International airport earned the best turnaround variance globally, with an increase of 10.6 percentage points between arriving and departing OTP. Furthermore, despite the runway constraints it operates under, Europe’s biggest airport, Heathrow (LHR), manages to keep departing flight OTP to within 2% of arriving OTP. Madrid (MAD) also has a minimal negative variance, with just over 1% between arriving and departing OTP.

Delhi’s Indira Gandhi International airport (DEL) secured the best turnaround performance among the Asia Pacific region, with a positive variance of 10.1 percentage points, and Beijing Capital International Airport (PEK) was a top contender with a 7.1 percent increase. Tokyo Haneda Airport (HND) received the highest arriving OTP of the group (84.5 percent) and managed to improve on that score for departing flights, with a positive turnaround variance of 4.9 percent. “The data shows faster aircraft turnaround times are trending globally. Airlines and airports worldwide are investing in OTP and their ability to handle late arriving flights,” added Benjamin.

Among the top performers in North America were Toronto’s Pearson International Airport (YYZ), with the highest turnaround variance for the region of 6.9 percentage points, and San Francisco International Airport (SFO), which came in second with an increase of 4.9 percentage points. Hartsfield-Jackson Atlanta International Airport (ATL), the largest airport examined for the North American region, achieved the highest arriving OTP (84.2 percent).

“A higher OTP for departing than arriving flights means aircraft are making up for delays of inbound flights through efficiencies in aircraft turnaround processes,” explains Mike Benjamin, CTO, OAG. “One late arrival can have a big ripple effect on subsequent outbound flights. The more airports can close this gap in OTP and return delayed aircraft to scheduled operating times, the easier it will be to reduce residual impact – delays, cancellations, missed connections — for passengers and airline customers.”

To qualify for inclusion in the Turnaround Tables, the OAG schedules database must have flight status data for at least 80 percent of all scheduled flights operated by an airport, and 12 months of data. OAG’s definition of on-time performance (OTP) is flights that arrive or depart within 14 minutes and 59 seconds (under 15 minutes) of their scheduled arrival/departure times. OAG’s OTP data is based on 57 million flight records for the full year 2017.
