A number of savvy travellers last week spotted BA tickets to the Middle East advertised through third-party agents for as little as £200 and duly snapped them up, MoneySavingExpert reports.
Destinations included Dubai and Tel Aviv.
However, BA has since cancelled a number of tickets due to an “exceptionally rare” pricing error.
The airline has apologised, refunded customers and offered them a £100 BA voucher.
Some customers though have called on BA to honour the tickets after booking accommodation and making other plans, leaving them out of pocket.
MoneySavingExpert highlighted a number of cases of travellers being left “high and dry”.
Deputy editor Guy Anker said as the tickets had been bought in good faith at a believable price, BA should “do the right thing and let them fly at the price they booked”.
A BA spokesperson said: "The fare was only available to a small number of agents over a short period of time, so only a small number of our customers have been affected.
"We have apologised and offered a gesture of goodwill. Errors like this are exceptionally rare, and if they do occur, under contract law, there is no binding contract between the parties."
