VIP shoppers boarded a two-hour flight to nowhere so they could get their hands on cut price airport bargains.
Passengers clambered onto the Air Busan Co flight which then soared up into the sky, briefly entered Japanese airspace and then landed back in South Korea’s Incheon Airport.
Because they’d technically left South Korea, the 130 customers onboard were able to hoover up some tax-free goodies once back on land.
The destination-less flight was laid on by Lotte Duty Free and cost the passengers nothing.
It was an attempt by the operator to boost business after an awful year of trading.
Seven South Korean carriers have operated similar flights, carrying about 8,000 passengers in total, Bloomsberg reports.
If they all flew for two hours in a Boeing 737, then they would have collectively spewed 1,440,000kg of Co2 into the atmosphere.
That is the equivalent amount of global heating accelerating emissions as a petrol car driving constantly for a year and four months.
Park Ju-hyun, a 31-year-old office worker from Seoul, paid about 90,000 won ($£56) for a flight-to-nowhere ticket in March.
She ended up spending £420 on cosmetics.
“It was nice to be back at the airport,” she told Bloomberg.
The duty-free market was big business before the pandemic struck and global passengers plunged from 4.5billion in 2019 to 1.6billion last year.
The market was on track to reach just shy of £100billion by 2027, according to Verified Market Research.
Annual revenue for Swiss duty-free giant Dufry AG, which has shops worldwide, dropped by 71 per cent last year.
Shoppers such as Hyun Jung-a, who was onboard the flight from and to Incheon Airport, bagged some big bargains including a Chanel bag, shoes and cosmetics.
“I saw a lot of people with bags full of duty-free items,” she said.
“I tell all my friends that it’s worth taking the flight because of the duty-free shopping opportunity.”
Sung Junewon, an analyst at Shinhan Investment Corp. in Seoul, said the contribution to the industry from the flights to nowhere was “small” but “better than nothing.”
