However, whether the airline will honour the fare is up to them. Air New Zealand and Virgin Australia have also previously recalled tickets issued in error, upsetting passengers. Occasionally airlines will allow travel on error fares to cache in on good will and better publicity - as Hong Kong Airways did in 2019 when it allowed passengers to fly to the US for $900 return on tickets issued in error.
Other airlines never realise tickets were issued in error, until too late.
In the early 2000s, several websites and flight clubs were set up to share "error fares" for thrifty travellers looking to bag a bargain. One website run by New Zealand-exiled Mega Upload founder Finn Batato, specialised in scraping the net for first-class tickets and alerting subscribers when they were listed for less than 10 per cent of historic rates.
More recently airlines have been tightening up on tickets sold in error due to rising costs in travel.
Since 2015, US airlines have been able to cancel fares exploiting errors or listed via Online Travel Agencies by mistake.
