SINGAPORE - A woman is suing Singapore Airlines (SIA) for an injury she sustained while on board one of its flights.

Mrs Jennifer Green, 71, has filed a suit in the Supreme Court of Victoria in Australia, SIA confirmed on Thursday (Aug 11).

The incident happened on July 31, 2014. Mrs Green and her husband, Mr Colin Green, were on board SIA flight 228 from Melbourne to Singapore.

Mrs Green alleges that a flight attendant spilled a tray of drinks on her husband's lap which caused him to bump into her.

This caused her to injure her foot, after hitting it against the metal footrest in front of her seat. This, she claims, aggravated her diabetes and rheumatoid arthritis, reported Australian newspaper The Age.

Mrs Green is asking SIA to compensate her for resulting hospital and medical expenses.

The Age reported that Mrs Green's writ stated that the mishap caused her "soft tissue injury caused by a blow to the right lower leg; development of right leg cellulitis caused by the said blow to the right lower leg; aggravation of rheumatoid arthritis; aggravation of type-one diabetes".

The writ also says her prognosis is "uncertain".

SIA said it is unable to comment on queries from The Straits Times on its next course of action, whether the air stewardess is still working with the SIA, and whether it is in touch in with the couple.

"Singapore Airlines can confirm that a suit has been filed in the Supreme Court of Victoria but we are unable to comment beyond that as it is now a matter before the courts," a spokesman said.
