Chinese are last-minute bookers when it comes to holidays, while Americans don’t worry about the price, a new survey reveals. Nearly half of Chinese respondents to a Worldpay survey planned their trip just two to four weeks before taking it. Chinese travellers also ranked highest in the survey for last-minute flight purchases. The survey polled travellers from the US, China, Brazil, India, Germany and Australia. On the opposite end of spontaneity are Australians, who were the most prepared travellers, with a quarter of respondents saying they planned their trip six months or more before departure. Perhaps, for good reason, though. Nearly half said their most recent trip lasted for three weeks or more. US consumers, meanwhile, are the least price sensitive when planning vacations, with 54 per cent admitting they don’t let sales on fares or room rates impact their destination choice. Worldpay, a payments processing technology company, surveyed 12,000 travellers who booked a flight online in the past year. Americans are the most likely use make their flight bookings on credit, with 84 per cent using credit cards, compared to just 4 per cent using debit cards. This compared to Australia, where 66 per cent paid using a credit card and 13 per cent debit. Alibaba-owned Alipay, which is similar to PayPal, had a big chunk of Chinese flight payments. WorldPay found that 45 per cent of Chinese respondents used credit cards and 30 per cent used Alipay, with the e-payment system’s popularity largely driven by under-35 travelers.
