Cathay Pacific will honour first-class airfares sold at economy-class prices, it said today, as a handful of lucky passengers booked tickets for a fraction of the normal price.

Tickets worth up to £15,000 from Vietnam to New York were sold for just £1,300, which works out at just £0.15 per mile. The typical rate is £1.66 per mile. 

A technical glitch saw several thousand first-class and business-class tickets sold for economy-class prices on the airline’s website on 1 January.
