Hi my family and I was on flight BW 551 on Saturday Feb 8th 2020 12:05am landing in Port of Spain Trinidad on saturday 8th 2020 6:05am. while on aircraft mid way we all started feeling abit nauseous so we ask the air hostess for water . Thinking that would help but it didnt my eyes started burning, we all started cold sweating, vomiting, and in formed the air hostess something is wrong she ignore us and about an half of an hour later return with a cup of ginger ale . All three of us was vomiting . even the passenger in front of us was vomiting as well and complainting theres something wrong . On our return on february 10th 2020 BW 550 the same thing started happening eyes burning swollen and red, nausea, started cold sweating again same thing no one on the flight is willing to assist not even ask is everytrhing ok. This is unacceptable, this was our worst flight ever. passengers are: Samantha wolff, parbatie roberts, leelawatie boodram. contact number : [protected] .
