Flight attendant Jamila Hardwick shared a few travel tips when flying on an airplane, like never to order a hot drink during a flight.
So why should you never order a hot tea or coffee during a flight? Because the cabin pipes and water tanks are rarely ever cleaned; maybe... once every few years. YUCK.
Hardwick also advises everyone to bring their own sanitary wipes for the trays when flying and to not ask flight attendants to help you with luggage, because they're not on the clock until the plane doors are shut. She also recommends bringing your own pillow when flying, because those pillows and blankets are rarely washed well. Carbonated diet drinks take a little longer to pour because they usually fizz up due to the elevation and air pressure.
