My girlfriend and I were flying in economy. The woman next to me sitting in the aisle seat -(row of three seats) was putting on nail polish. It did not bother me but my girlfriend cannot tolerate the smell of nail polish, it makes her sick. She asked the woman to stop pputting on the nail polish and close the bottle. The woman refused. Should my girlfriend have complained to the FA or was it okay for the woman to put on the nail polish?
