Buenos Aires Aeroparque closed for second day, 900 flights affected
Why It MattersA single runway closure can push a city's secondary airport traffic up nearly 80% overnight, showing how thin the redundancy is between paired airports serving one metro area.
What happened
Buenos Aires city airport Aeroparque remained closed for a second day on August 26 due to maintenance work on the main runway, with operations scheduled to resume at 16:00 on Thursday, August 27, following a 55-hour interruption.
Approximately 900 flights were affected by the closure. About 540 were redirected to Ezeiza Airport, while around 360 were rescheduled. The additional traffic increased the number of flights at Ezeiza from approximately 530 to 940 during the period, a rise of nearly 80%. Flights operated by Aerolíneas Argentinas, JetSmart, Flybondi, LATAM, GOL, Andes, Avianca, and Paranair were among those affected.
Passengers were advised to verify both their departure time and departure airport, as Ezeiza is located approximately one hour's drive from Buenos Aires city center, compared with about 15 minutes for Aeroparque.
How it unfolded
Operations are scheduled to resume, marking the end of a 55-hour interruption.
Aeroparque remains closed for a second day for main runway maintenance work.
Industry impact & what to watch
Planned runway maintenance at a single-runway city airport shows how quickly a scheduled closure can strain a metro area's air-travel capacity when there is only one realistic alternate. Redirecting roughly 540 flights onto Ezeiza pushed that airport's flight count from about 530 to 940 over the closure period, a load increase that tests ramp, gate and ground-handling capacity built for lower volumes.
This is how paired-airport systems generally function under stress: the secondary field absorbs displaced traffic, but passengers and operators absorb the routing and ground-transport cost, since Ezeiza sits roughly an hour from the city center against about 15 minutes for Aeroparque. The eight carriers named, Aerolíneas Argentinas, JetSmart, Flybondi, LATAM, GOL, Andes, Avianca, and Paranair, each had to manage rebooking or diversion of passengers across two airports with different access times.
The reopening set for 16:00 on Thursday, August 27 is the next checkpoint: whether Aeroparque resumes on schedule will determine how quickly the roughly 360 rescheduled flights and the diverted traffic at Ezeiza normalize back to typical volumes.
