The Zalmanovich family, from HodSharon, Israel, claim they were told to leave after their eight-year-old son began to cry just before the connecting flight from Zurich to Geneva was scheduled to depart.
The boy’s mother told the Israel Hayom newspaper that cabin crew on the Swiss International Air Lines flight apologised to other passengers rather than asking the family if they needed help after the child became ill.
“They shamefully kicked us off the flight. We were left with our luggage, shocked and humiliated,” Ms Zalmanovich said.
“It was 10pm and luckily we were able to catch the last train to Geneva.”
Swiss International Air Lines, which is a wholly-owned subsidiary of Lufthansa, reportedly agreed to restore the family’s seats on a return flight for 2,000 francs (£1,356), but they declined to be flown back by the airline and took an El Al flight instead.
“We are aware of this deeply regrettable incident,” the company said in a statement to The Independent.
“We are still clarifying exactly what happened and why with all the parties involved, so we are unable to make any further comment at the present time. But it can be assured that our staff in Tel Aviv are in close contact with the family concerned.”
