I was on a flight recently and suddenly had a hacking cough, kept sipping on water, started wheezing , people around me got concerned, Felt a bit faint and light headedness.. Somehow ran to the washroom. and relaxed and caught my breath, came back sipped on water.. felt like i was also having some trapped gas ,and was burping and coughing simultaneously. Anyone have any issues travelling via planes? What preventive measures can I take, I havent boarded a flight ever since due to fear. Woman in 40s now, have travelled earlies with no issues.
