Consumer rights expert Which? Holiday has urged airlines to introduce the 24-hour rule, which would give travellers a full day to double-check their details and alter any errors.
Rochelle Turner, a spokesperson for the body said: "There should a commitment or some sort of guarantee to people rather than it being arbitrary or depending on which airline you are going with."
She added that many of the problems consumers face online are basic human errors.
"It would be interesting to know how much money they are earning from the mistakes that consumers make and if that is the reason why they are not taking a more proactive stance in helping people who are making innocent mistakes," she noted.
Echoing Ms Turner's comments, a recent report from the Air Transport Users' Council is seeking to persuade operators to change their online booking policies.
