Singapore Airlines said it has now stopped serving peanuts as complimentary snacks on flights.
The move comes after SIA announced last year it would review its policy after a small child suffered a severe allergic reaction after a nearby passenger opened a pack of peanuts.
A three-year-old boy went into anaphylactic shock after being exposed to the nuts.
The airline confirmed it stopped serving peanuts in April but other nuts are still available.
"Cashews, macadamia nuts and walnuts continue to be served in Suites and First Class, while almonds and cashews continue to be served in Business Class and Premium Economy Class," it said.
SIA does offer nut-free special dietary meals but said it cannot guarantee a completely nut-free environment aboard its flights.
"It’s not unusual for other passengers on our flights to be served meals and snacks containing nuts or their derivatives. We also have no control over passengers consuming their own snacks or meals on board, which may contain nuts or their derivatives," it says on its website.
