Quick facts

  • Between 2018 – 2019, Atlanta Airport successfully launched over 380,000 flights on schedule, with 82% of their total outbound flights leaving on-time.

  • Last year over 110,000 flights were delayed attempting to leave Chicago airport, which is nearly a quarter of the airport's outbound flights in 2018.

  • In 2017, one British Airways flight suffered an unusual delay when the flight was unable to leave due to insufficient supplies of toilet paper. The flight was held at London Gatwick for five hours before it was finally able to leave.

  • Hong Kong International airport has a nine-hole golf course right next to terminal 2 which is open to travellers. This is good news seeing as 30% of flights out of this airport were delayed last year.
