A Reddit user shared a story about a fellow passenger on a Delta Air Lines flight who changed their baby’s diaper right in their seat, leaving a strong and unpleasant smell. The user, disturbed by the odor, was forced to move seats, prompting a flight attendant to intervene and ask the parent to change the diaper in the bathroom. The flight attendant explained the unhygienic nature of changing diapers in the seat, and the parent thankfully complied without argument. Other Reddit users also chimed in, expressing their own experiences with similar situations and highlighting the importance of proper hygiene and consideration for fellow passengers.
