During takeoff and landing, all "personal items," including purses, must be stowed either under the seat in front of you or in the overhead bin. This is a federal safety regulation designed to ensure that the footwell and aisles remain completely clear of trip hazards in the event of an emergency evacuation. Once the aircraft has reached cruising altitude and the "Fasten Seatbelt" sign is turned off, you are free to pull your purse out and keep it on your lap or next to you. However, if you are sitting in an emergency exit row or a bulkhead seat (the first row of a section with no seat in front of you), you are strictly prohibited from keeping any bags at your feet at any time during the flight; everything must go in the overhead bin for the duration of the journey. In 2026, with airlines enforcing tighter cabin space, flight attendants are increasingly vigilant about ensuring purses do not block the paths of other passengers, so keeping it tucked under the seat is not just a rule, but a courtesy to your seatmates.
